By contrast, +the GNU General Public License is intended to guarantee your freedom to +share and change all versions of a program--to make sure it remains free +software for all its users. We, the Free Software Foundation, use the +GNU General Public License for most of our software; it applies also to +any other work released this way by its authors. You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + + To protect your rights, we need to prevent others from denying you +these rights or asking you to surrender the rights. Therefore, you have +certain responsibilities if you distribute copies of the software, or if +you modify it: responsibilities to respect the freedom of others. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must pass on to the recipients the same +freedoms that you received. You must make sure that they, too, receive +or can get the source code. And you must show them these terms so they +know their rights. + + Developers that use the GNU GPL protect your rights with two steps: +(1) assert copyright on the software, and (2) offer you this License +giving you legal permission to copy, distribute and/or modify it. + + For the developers' and authors' protection, the GPL clearly explains +that there is no warranty for this free software. For both users' and +authors' sake, the GPL requires that modified versions be marked as +changed, so that their problems will not be attributed erroneously to +authors of previous versions. + + Some devices are designed to deny users access to install or run +modified versions of the software inside them, although the manufacturer +can do so. This is fundamentally incompatible with the aim of +protecting users' freedom to change the software. The systematic +pattern of such abuse occurs in the area of products for individuals to +use, which is precisely where it is most unacceptable. Therefore, we +have designed this version of the GPL to prohibit the practice for those +products. If such problems arise substantially in other domains, we +stand ready to extend this provision to those domains in future versions +of the GPL, as needed to protect the freedom of users. + + Finally, every program is threatened constantly by software patents. +States should not allow patents to restrict development and use of +software on general-purpose computers, but in those that do, we wish to +avoid the special danger that patents applied to a free program could +make it effectively proprietary. To prevent this, the GPL assures that +patents cannot be used to render the program non-free. + + The precise terms and conditions for copying, distribution and +modification follow. + + TERMS AND CONDITIONS + + 0. Definitions. + + "This License" refers to version 3 of the GNU General Public License. + + "Copyright" also means copyright-like laws that apply to other kinds of +works, such as semiconductor masks. + + "The Program" refers to any copyrightable work licensed under this +License. Each licensee is addressed as "you". "Licensees" and +"recipients" may be individuals or organizations. + + To "modify" a work means to copy from or adapt all or part of the work +in a fashion requiring copyright permission, other than the making of an +exact copy. The resulting work is called a "modified version" of the +earlier work or a work "based on" the earlier work. + + A "covered work" means either the unmodified Program or a work based +on the Program. + + To "propagate" a work means to do anything with it that, without +permission, would make you directly or secondarily liable for +infringement under applicable copyright law, except executing it on a +computer or modifying a private copy. Propagation includes copying, +distribution (with or without modification), making available to the +public, and in some countries other activities as well. + + To "convey" a work means any kind of propagation that enables other +parties to make or receive copies. Mere interaction with a user through +a computer network, with no transfer of a copy, is not conveying. + + An interactive user interface displays "Appropriate Legal Notices" +to the extent that it includes a convenient and prominently visible +feature that (1) displays an appropriate copyright notice, and (2) +tells the user that there is no warranty for the work (except to the +extent that warranties are provided), that licensees may convey the +work under this License, and how to view a copy of this License. If +the interface presents a list of user commands or options, such as a +menu, a prominent item in the list meets this criterion. + + 1. Source Code. + + The "source code" for a work means the preferred form of the work +for making modifications to it. "Object code" means any non-source +form of a work. + + A "Standard Interface" means an interface that either is an official +standard defined by a recognized standards body, or, in the case of +interfaces specified for a particular programming language, one that +is widely used among developers working in that language. + + The "System Libraries" of an executable work include anything, other +than the work as a whole, that (a) is included in the normal form of +packaging a Major Component, but which is not part of that Major +Component, and (b) serves only to enable use of the work with that +Major Component, or to implement a Standard Interface for which an +implementation is available to the public in source code form. A +"Major Component", in this context, means a major essential component +(kernel, window system, and so on) of the specific operating system +(if any) on which the executable work runs, or a compiler used to +produce the work, or an object code interpreter used to run it. + + The "Corresponding Source" for a work in object code form means all +the source code needed to generate, install, and (for an executable +work) run the object code and to modify the work, including scripts to +control those activities. However, it does not include the work's +System Libraries, or general-purpose tools or generally available free +programs which are used unmodified in performing those activities but +which are not part of the work. For example, Corresponding Source +includes interface definition files associated with source files for +the work, and the source code for shared libraries and dynamically +linked subprograms that the work is specifically designed to require, +such as by intimate data communication or control flow between those +subprograms and other parts of the work. + + The Corresponding Source need not include anything that users +can regenerate automatically from other parts of the Corresponding +Source. + + The Corresponding Source for a work in source code form is that +same work. + + 2. Basic Permissions. + + All rights granted under this License are granted for the term of +copyright on the Program, and are irrevocable provided the stated +conditions are met. This License explicitly affirms your unlimited +permission to run the unmodified Program. The output from running a +covered work is covered by this License only if the output, given its +content, constitutes a covered work. This License acknowledges your +rights of fair use or other equivalent, as provided by copyright law. + + You may make, run and propagate covered works that you do not +convey, without conditions so long as your license otherwise remains +in force. You may convey covered works to others for the sole purpose +of having them make modifications exclusively for you, or provide you +with facilities for running those works, provided that you comply with +the terms of this License in conveying all material for which you do +not control copyright. Those thus making or running the covered works +for you must do so exclusively on your behalf, under your direction +and control, on terms that prohibit them from making any copies of +your copyrighted material outside their relationship with you. + + Conveying under any other circumstances is permitted solely under +the conditions stated below. Sublicensing is not allowed; section 10 +makes it unnecessary. + + 3. Protecting Users' Legal Rights From Anti-Circumvention Law. + + No covered work shall be deemed part of an effective technological +measure under any applicable law fulfilling obligations under article +11 of the WIPO copyright treaty adopted on 20 December 1996, or +similar laws prohibiting or restricting circumvention of such +measures. + + When you convey a covered work, you waive any legal power to forbid +circumvention of technological measures to the extent such circumvention +is effected by exercising rights under this License with respect to +the covered work, and you disclaim any intention to limit operation or +modification of the work as a means of enforcing, against the work's +users, your or third parties' legal rights to forbid circumvention of +technological measures. + + 4. Conveying Verbatim Copies. + + You may convey verbatim copies of the Program's source code as you +receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy an appropriate copyright notice; +keep intact all notices stating that this License and any +non-permissive terms added in accord with section 7 apply to the code; +keep intact all notices of the absence of any warranty; and give all +recipients a copy of this License along with the Program. + + You may charge any price or no price for each copy that you convey, +and you may offer support or warranty protection for a fee. + + 5. Conveying Modified Source Versions. + + You may convey a work based on the Program, or the modifications to +produce it from the Program, in the form of source code under the +terms of section 4, provided that you also meet all of these conditions: + + a) The work must carry prominent notices stating that you modified + it, and giving a relevant date. + + b) The work must carry prominent notices stating that it is + released under this License and any conditions added under section + 7. This requirement modifies the requirement in section 4 to + "keep intact all notices". + + c) You must license the entire work, as a whole, under this + License to anyone who comes into possession of a copy. This + License will therefore apply, along with any applicable section 7 + additional terms, to the whole of the work, and all its parts, + regardless of how they are packaged. This License gives no + permission to license the work in any other way, but it does not + invalidate such permission if you have separately received it. + + d) If the work has interactive user interfaces, each must display + Appropriate Legal Notices; however, if the Program has interactive + interfaces that do not display Appropriate Legal Notices, your + work need not make them do so. + + A compilation of a covered work with other separate and independent +works, which are not by their nature extensions of the covered work, +and which are not combined with it such as to form a larger program, +in or on a volume of a storage or distribution medium, is called an +"aggregate" if the compilation and its resulting copyright are not +used to limit the access or legal rights of the compilation's users +beyond what the individual works permit. Inclusion of a covered work +in an aggregate does not cause this License to apply to the other +parts of the aggregate. + + 6. Conveying Non-Source Forms. + + You may convey a covered work in object code form under the terms +of sections 4 and 5, provided that you also convey the +machine-readable Corresponding Source under the terms of this License, +in one of these ways: + + a) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by the + Corresponding Source fixed on a durable physical medium + customarily used for software interchange. + + b) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by a + written offer, valid for at least three years and valid for as + long as you offer spare parts or customer support for that product + model, to give anyone who possesses the object code either (1) a + copy of the Corresponding Source for all the software in the + product that is covered by this License, on a durable physical + medium customarily used for software interchange, for a price no + more than your reasonable cost of physically performing this + conveying of source, or (2) access to copy the + Corresponding Source from a network server at no charge. + + c) Convey individual copies of the object code with a copy of the + written offer to provide the Corresponding Source. This + alternative is allowed only occasionally and noncommercially, and + only if you received the object code with such an offer, in accord + with subsection 6b. + + d) Convey the object code by offering access from a designated + place (gratis or for a charge), and offer equivalent access to the + Corresponding Source in the same way through the same place at no + further charge. You need not require recipients to copy the + Corresponding Source along with the object code. If the place to + copy the object code is a network server, the Corresponding Source + may be on a different server (operated by you or a third party) + that supports equivalent copying facilities, provided you maintain + clear directions next to the object code saying where to find the + Corresponding Source. Regardless of what server hosts the + Corresponding Source, you remain obligated to ensure that it is + available for as long as needed to satisfy these requirements. + + e) Convey the object code using peer-to-peer transmission, provided + you inform other peers where the object code and Corresponding + Source of the work are being offered to the general public at no + charge under subsection 6d. + + A separable portion of the object code, whose source code is excluded +from the Corresponding Source as a System Library, need not be +included in conveying the object code work. + + A "User Product" is either (1) a "consumer product", which means any +tangible personal property which is normally used for personal, family, +or household purposes, or (2) anything designed or sold for incorporation +into a dwelling. In determining whether a product is a consumer product, +doubtful cases shall be resolved in favor of coverage. For a particular +product received by a particular user, "normally used" refers to a +typical or common use of that class of product, regardless of the status +of the particular user or of the way in which the particular user +actually uses, or expects or is expected to use, the product. A product +is a consumer product regardless of whether the product has substantial +commercial, industrial or non-consumer uses, unless such uses represent +the only significant mode of use of the product. + + "Installation Information" for a User Product means any methods, +procedures, authorization keys, or other information required to install +and execute modified versions of a covered work in that User Product from +a modified version of its Corresponding Source. The information must +suffice to ensure that the continued functioning of the modified object +code is in no case prevented or interfered with solely because +modification has been made. + + If you convey an object code work under this section in, or with, or +specifically for use in, a User Product, and the conveying occurs as +part of a transaction in which the right of possession and use of the +User Product is transferred to the recipient in perpetuity or for a +fixed term (regardless of how the transaction is characterized), the +Corresponding Source conveyed under this section must be accompanied +by the Installation Information. But this requirement does not apply +if neither you nor any third party retains the ability to install +modified object code on the User Product (for example, the work has +been installed in ROM). + + The requirement to provide Installation Information does not include a +requirement to continue to provide support service, warranty, or updates +for a work that has been modified or installed by the recipient, or for +the User Product in which it has been modified or installed. Access to a +network may be denied when the modification itself materially and +adversely affects the operation of the network or violates the rules and +protocols for communication across the network. + + Corresponding Source conveyed, and Installation Information provided, +in accord with this section must be in a format that is publicly +documented (and with an implementation available to the public in +source code form), and must require no special password or key for +unpacking, reading or copying. + + 7. Additional Terms. + + "Additional permissions" are terms that supplement the terms of this +License by making exceptions from one or more of its conditions. +Additional permissions that are applicable to the entire Program shall +be treated as though they were included in this License, to the extent +that they are valid under applicable law. If additional permissions +apply only to part of the Program, that part may be used separately +under those permissions, but the entire Program remains governed by +this License without regard to the additional permissions. + + When you convey a copy of a covered work, you may at your option +remove any additional permissions from that copy, or from any part of +it. (Additional permissions may be written to require their own +removal in certain cases when you modify the work.) You may place +additional permissions on material, added by you to a covered work, +for which you have or can give appropriate copyright permission. + + Notwithstanding any other provision of this License, for material you +add to a covered work, you may (if authorized by the copyright holders of +that material) supplement the terms of this License with terms: + + a) Disclaiming warranty or limiting liability differently from the + terms of sections 15 and 16 of this License; or + + b) Requiring preservation of specified reasonable legal notices or + author attributions in that material or in the Appropriate Legal + Notices displayed by works containing it; or + + c) Prohibiting misrepresentation of the origin of that material, or + requiring that modified versions of such material be marked in + reasonable ways as different from the original version; or + + d) Limiting the use for publicity purposes of names of licensors or + authors of the material; or + + e) Declining to grant rights under trademark law for use of some + trade names, trademarks, or service marks; or + + f) Requiring indemnification of licensors and authors of that + material by anyone who conveys the material (or modified versions of + it) with contractual assumptions of liability to the recipient, for + any liability that these contractual assumptions directly impose on + those licensors and authors. + + All other non-permissive additional terms are considered "further +restrictions" within the meaning of section 10. If the Program as you +received it, or any part of it, contains a notice stating that it is +governed by this License along with a term that is a further +restriction, you may remove that term. If a license document contains +a further restriction but permits relicensing or conveying under this +License, you may add to a covered work material governed by the terms +of that license document, provided that the further restriction does +not survive such relicensing or conveying. + + If you add terms to a covered work in accord with this section, you +must place, in the relevant source files, a statement of the +additional terms that apply to those files, or a notice indicating +where to find the applicable terms. + + Additional terms, permissive or non-permissive, may be stated in the +form of a separately written license, or stated as exceptions; +the above requirements apply either way. + + 8. Termination. + + You may not propagate or modify a covered work except as expressly +provided under this License. Any attempt otherwise to propagate or +modify it is void, and will automatically terminate your rights under +this License (including any patent licenses granted under the third +paragraph of section 11). + + However, if you cease all violation of this License, then your +license from a particular copyright holder is reinstated (a) +provisionally, unless and until the copyright holder explicitly and +finally terminates your license, and (b) permanently, if the copyright +holder fails to notify you of the violation by some reasonable means +prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + + Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, you do not qualify to receive new licenses for the same +material under section 10. + + 9. Acceptance Not Required for Having Copies. + + You are not required to accept this License in order to receive or +run a copy of the Program. Ancillary propagation of a covered work +occurring solely as a consequence of using peer-to-peer transmission +to receive a copy likewise does not require acceptance. However, +nothing other than this License grants you permission to propagate or +modify any covered work. These actions infringe copyright if you do +not accept this License. Therefore, by modifying or propagating a +covered work, you indicate your acceptance of this License to do so. + + 10. Automatic Licensing of Downstream Recipients. + + Each time you convey a covered work, the recipient automatically +receives a license from the original licensors, to run, modify and +propagate that work, subject to this License. You are not responsible +for enforcing compliance by third parties with this License. + + An "entity transaction" is a transaction transferring control of an +organization, or substantially all assets of one, or subdividing an +organization, or merging organizations. If propagation of a covered +work results from an entity transaction, each party to that +transaction who receives a copy of the work also receives whatever +licenses to the work the party's predecessor in interest had or could +give under the previous paragraph, plus a right to possession of the +Corresponding Source of the work from the predecessor in interest, if +the predecessor has it or can get it with reasonable efforts. + + You may not impose any further restrictions on the exercise of the +rights granted or affirmed under this License. For example, you may +not impose a license fee, royalty, or other charge for exercise of +rights granted under this License, and you may not initiate litigation +(including a cross-claim or counterclaim in a lawsuit) alleging that +any patent claim is infringed by making, using, selling, offering for +sale, or importing the Program or any portion of it. + + 11. Patents. + + A "contributor" is a copyright holder who authorizes use under this +License of the Program or a work on which the Program is based. The +work thus licensed is called the contributor's "contributor version". + + A contributor's "essential patent claims" are all patent claims +owned or controlled by the contributor, whether already acquired or +hereafter acquired, that would be infringed by some manner, permitted +by this License, of making, using, or selling its contributor version, +but do not include claims that would be infringed only as a +consequence of further modification of the contributor version. For +purposes of this definition, "control" includes the right to grant +patent sublicenses in a manner consistent with the requirements of +this License. + + Each contributor grants you a non-exclusive, worldwide, royalty-free +patent license under the contributor's essential patent claims, to +make, use, sell, offer for sale, import and otherwise run, modify and +propagate the contents of its contributor version. + + In the following three paragraphs, a "patent license" is any express +agreement or commitment, however denominated, not to enforce a patent +(such as an express permission to practice a patent or covenant not to +sue for patent infringement). To "grant" such a patent license to a +party means to make such an agreement or commitment not to enforce a +patent against the party. + + If you convey a covered work, knowingly relying on a patent license, +and the Corresponding Source of the work is not available for anyone +to copy, free of charge and under the terms of this License, through a +publicly available network server or other readily accessible means, +then you must either (1) cause the Corresponding Source to be so +available, or (2) arrange to deprive yourself of the benefit of the +patent license for this particular work, or (3) arrange, in a manner +consistent with the requirements of this License, to extend the patent +license to downstream recipients. "Knowingly relying" means you have +actual knowledge that, but for the patent license, your conveying the +covered work in a country, or your recipient's use of the covered work +in a country, would infringe one or more identifiable patents in that +country that you have reason to believe are valid. + + If, pursuant to or in connection with a single transaction or +arrangement, you convey, or propagate by procuring conveyance of, a +covered work, and grant a patent license to some of the parties +receiving the covered work authorizing them to use, propagate, modify +or convey a specific copy of the covered work, then the patent license +you grant is automatically extended to all recipients of the covered +work and works based on it. + + A patent license is "discriminatory" if it does not include within +the scope of its coverage, prohibits the exercise of, or is +conditioned on the non-exercise of one or more of the rights that are +specifically granted under this License. You may not convey a covered +work if you are a party to an arrangement with a third party that is +in the business of distributing software, under which you make payment +to the third party based on the extent of your activity of conveying +the work, and under which the third party grants, to any of the +parties who would receive the covered work from you, a discriminatory +patent license (a) in connection with copies of the covered work +conveyed by you (or copies made from those copies), or (b) primarily +for and in connection with specific products or compilations that +contain the covered work, unless you entered into that arrangement, +or that patent license was granted, prior to 28 March 2007. + + Nothing in this License shall be construed as excluding or limiting +any implied license or other defenses to infringement that may +otherwise be available to you under applicable patent law. + + 12. No Surrender of Others' Freedom. + + If conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot convey a +covered work so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you may +not convey it at all. For example, if you agree to terms that obligate you +to collect a royalty for further conveying from those to whom you convey +the Program, the only way you could satisfy both those terms and this +License would be to refrain entirely from conveying the Program. + + 13. Use with the GNU Affero General Public License. + + Notwithstanding any other provision of this License, you have +permission to link or combine any covered work with a work licensed +under version 3 of the GNU Affero General Public License into a single +combined work, and to convey the resulting work. The terms of this +License will continue to apply to the part which is the covered work, +but the special requirements of the GNU Affero General Public License, +section 13, concerning interaction through a network will apply to the +combination as such. + + 14. Revised Versions of this License. + + The Free Software Foundation may publish revised and/or new versions of +the GNU General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + + Each version is given a distinguishing version number. If the +Program specifies that a certain numbered version of the GNU General +Public License "or any later version" applies to it, you have the +option of following the terms and conditions either of that numbered +version or of any later version published by the Free Software +Foundation. If the Program does not specify a version number of the +GNU General Public License, you may choose any version ever published +by the Free Software Foundation. + + If the Program specifies that a proxy can decide which future +versions of the GNU General Public License can be used, that proxy's +public statement of acceptance of a version permanently authorizes you +to choose that version for the Program. + + Later license versions may give you additional or different +permissions. However, no additional obligations are imposed on any +author or copyright holder as a result of your choosing to follow a +later version. + + 15. Disclaimer of Warranty. + + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY +APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY +OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, +THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM +IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF +ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. Limitation of Liability. + + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS +THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY +GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE +USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF +DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD +PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), +EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF +SUCH DAMAGES. + + 17. Interpretation of Sections 15 and 16. + + If the disclaimer of warranty and limitation of liability provided +above cannot be given local legal effect according to their terms, +reviewing courts shall apply local law that most closely approximates +an absolute waiver of all civil liability in connection with the +Program, unless a warranty or assumption of liability accompanies a +copy of the Program in return for a fee. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +state the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software: you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation, either version 3 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program. If not, see . + +Also add information on how to contact you by electronic and paper mail. + + If the program does terminal interaction, make it output a short +notice like this when it starts in an interactive mode: + + Copyright (C) + This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, your program's commands +might be different; for a GUI interface, you would use an "about box". + + You should also get your employer (if you work as a programmer) or school, +if any, to sign a "copyright disclaimer" for the program, if necessary. +For more information on this, and how to apply and follow the GNU GPL, see +. + + The GNU General Public License does not permit incorporating your program +into proprietary programs. If your program is a subroutine library, you +may consider it more useful to permit linking proprietary applications with +the library. If this is what you want to do, use the GNU Lesser General +Public License instead of this License. But first, please read +. diff --git a/libusb/COPYING_LGPL.txt b/libusb/COPYING_LGPL.txt new file mode 100644 index 0000000..b14ca0a --- /dev/null +++ b/libusb/COPYING_LGPL.txt @@ -0,0 +1,165 @@ + GNU LESSER GENERAL PUBLIC LICENSE + Version 3, 29 June 2007 + + Copyright (C) 2007 Free Software Foundation, Inc. + Everyone is permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed. + + + This version of the GNU Lesser General Public License incorporates +the terms and conditions of version 3 of the GNU General Public +License, supplemented by the additional permissions listed below. + + 0. Additional Definitions. + + As used herein, "this License" refers to version 3 of the GNU Lesser +General Public License, and the "GNU GPL" refers to version 3 of the GNU +General Public License. + + "The Library" refers to a covered work governed by this License, +other than an Application or a Combined Work as defined below. + + An "Application" is any work that makes use of an interface provided +by the Library, but which is not otherwise based on the Library. +Defining a subclass of a class defined by the Library is deemed a mode +of using an interface provided by the Library. + + A "Combined Work" is a work produced by combining or linking an +Application with the Library. The particular version of the Library +with which the Combined Work was made is also called the "Linked +Version". + + The "Minimal Corresponding Source" for a Combined Work means the +Corresponding Source for the Combined Work, excluding any source code +for portions of the Combined Work that, considered in isolation, are +based on the Application, and not on the Linked Version. + + The "Corresponding Application Code" for a Combined Work means the +object code and/or source code for the Application, including any data +and utility programs needed for reproducing the Combined Work from the +Application, but excluding the System Libraries of the Combined Work. + + 1. Exception to Section 3 of the GNU GPL. + + You may convey a covered work under sections 3 and 4 of this License +without being bound by section 3 of the GNU GPL. + + 2. Conveying Modified Versions. + + If you modify a copy of the Library, and, in your modifications, a +facility refers to a function or data to be supplied by an Application +that uses the facility (other than as an argument passed when the +facility is invoked), then you may convey a copy of the modified +version: + + a) under this License, provided that you make a good faith effort to + ensure that, in the event an Application does not supply the + function or data, the facility still operates, and performs + whatever part of its purpose remains meaningful, or + + b) under the GNU GPL, with none of the additional permissions of + this License applicable to that copy. + + 3. Object Code Incorporating Material from Library Header Files. + + The object code form of an Application may incorporate material from +a header file that is part of the Library. You may convey such object +code under terms of your choice, provided that, if the incorporated +material is not limited to numerical parameters, data structure +layouts and accessors, or small macros, inline functions and templates +(ten or fewer lines in length), you do both of the following: + + a) Give prominent notice with each copy of the object code that the + Library is used in it and that the Library and its use are + covered by this License. + + b) Accompany the object code with a copy of the GNU GPL and this license + document. + + 4. Combined Works. + + You may convey a Combined Work under terms of your choice that, +taken together, effectively do not restrict modification of the +portions of the Library contained in the Combined Work and reverse +engineering for debugging such modifications, if you also do each of +the following: + + a) Give prominent notice with each copy of the Combined Work that + the Library is used in it and that the Library and its use are + covered by this License. + + b) Accompany the Combined Work with a copy of the GNU GPL and this license + document. + + c) For a Combined Work that displays copyright notices during + execution, include the copyright notice for the Library among + these notices, as well as a reference directing the user to the + copies of the GNU GPL and this license document. + + d) Do one of the following: + + 0) Convey the Minimal Corresponding Source under the terms of this + License, and the Corresponding Application Code in a form + suitable for, and under terms that permit, the user to + recombine or relink the Application with a modified version of + the Linked Version to produce a modified Combined Work, in the + manner specified by section 6 of the GNU GPL for conveying + Corresponding Source. + + 1) Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that (a) uses at run time + a copy of the Library already present on the user's computer + system, and (b) will operate properly with a modified version + of the Library that is interface-compatible with the Linked + Version. + + e) Provide Installation Information, but only if you would otherwise + be required to provide such information under section 6 of the + GNU GPL, and only to the extent that such information is + necessary to install and execute a modified version of the + Combined Work produced by recombining or relinking the + Application with a modified version of the Linked Version. (If + you use option 4d0, the Installation Information must accompany + the Minimal Corresponding Source and Corresponding Application + Code. If you use option 4d1, you must provide the Installation + Information in the manner specified by section 6 of the GNU GPL + for conveying Corresponding Source.) + + 5. Combined Libraries. + + You may place library facilities that are a work based on the +Library side by side in a single library together with other library +facilities that are not Applications and are not covered by this +License, and convey such a combined library under terms of your +choice, if you do both of the following: + + a) Accompany the combined library with a copy of the same work based + on the Library, uncombined with any other library facilities, + conveyed under the terms of this License. + + b) Give prominent notice with the combined library that part of it + is a work based on the Library, and explaining where to find the + accompanying uncombined form of the same work. + + 6.

By contrast, +the GNU General Public License is intended to guarantee your freedom to +share and change all versions of a program--to make sure it remains free +software for all its users. We, the Free Software Foundation, use the +GNU General Public License for most of our software; it applies also to +any other work released this way by its authors. You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + + To protect your rights, we need to prevent others from denying you +these rights or asking you to surrender the rights. Therefore, you have +certain responsibilities if you distribute copies of the software, or if +you modify it: responsibilities to respect the freedom of others. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must pass on to the recipients the same +freedoms that you received. You must make sure that they, too, receive +or can get the source code. And you must show them these terms so they +know their rights. + + Developers that use the GNU GPL protect your rights with two steps: +(1) assert copyright on the software, and (2) offer you this License +giving you legal permission to copy, distribute and/or modify it. + + For the developers' and authors' protection, the GPL clearly explains +that there is no warranty for this free software. For both users' and +authors' sake, the GPL requires that modified versions be marked as +changed, so that their problems will not be attributed erroneously to +authors of previous versions. + + Some devices are designed to deny users access to install or run +modified versions of the software inside them, although the manufacturer +can do so. This is fundamentally incompatible with the aim of +protecting users' freedom to change the software. The systematic +pattern of such abuse occurs in the area of products for individuals to +use, which is precisely where it is most unacceptable. Therefore, we +have designed this version of the GPL to prohibit the practice for those +products. If such problems arise substantially in other domains, we +stand ready to extend this provision to those domains in future versions +of the GPL, as needed to protect the freedom of users. + + Finally, every program is threatened constantly by software patents. +States should not allow patents to restrict development and use of +software on general-purpose computers, but in those that do, we wish to +avoid the special danger that patents applied to a free program could +make it effectively proprietary. To prevent this, the GPL assures that +patents cannot be used to render the program non-free. + + The precise terms and conditions for copying, distribution and +modification follow. + + TERMS AND CONDITIONS + + 0. Definitions. + + "This License" refers to version 3 of the GNU General Public License. + + "Copyright" also means copyright-like laws that apply to other kinds of +works, such as semiconductor masks. + + "The Program" refers to any copyrightable work licensed under this +License. Each licensee is addressed as "you". "Licensees" and +"recipients" may be individuals or organizations. + + To "modify" a work means to copy from or adapt all or part of the work +in a fashion requiring copyright permission, other than the making of an +exact copy. The resulting work is called a "modified version" of the +earlier work or a work "based on" the earlier work. + + A "covered work" means either the unmodified Program or a work based +on the Program. + + To "propagate" a work means to do anything with it that, without +permission, would make you directly or secondarily liable for +infringement under applicable copyright law, except executing it on a +computer or modifying a private copy. Propagation includes copying, +distribution (with or without modification), making available to the +public, and in some countries other activities as well. + + To "convey" a work means any kind of propagation that enables other +parties to make or receive copies. Mere interaction with a user through +a computer network, with no transfer of a copy, is not conveying. + + An interactive user interface displays "Appropriate Legal Notices" +to the extent that it includes a convenient and prominently visible +feature that (1) displays an appropriate copyright notice, and (2) +tells the user that there is no warranty for the work (except to the +extent that warranties are provided), that licensees may convey the +work under this License, and how to view a copy of this License. If +the interface presents a list of user commands or options, such as a +menu, a prominent item in the list meets this criterion. + + 1. Source Code. + + The "source code" for a work means the preferred form of the work +for making modifications to it. "Object code" means any non-source +form of a work. + + A "Standard Interface" means an interface that either is an official +standard defined by a recognized standards body, or, in the case of +interfaces specified for a particular programming language, one that +is widely used among developers working in that language. + + The "System Libraries" of an executable work include anything, other +than the work as a whole, that (a) is included in the normal form of +packaging a Major Component, but which is not part of that Major +Component, and (b) serves only to enable use of the work with that +Major Component, or to implement a Standard Interface for which an +implementation is available to the public in source code form. A +"Major Component", in this context, means a major essential component +(kernel, window system, and so on) of the specific operating system +(if any) on which the executable work runs, or a compiler used to +produce the work, or an object code interpreter used to run it. + + The "Corresponding Source" for a work in object code form means all +the source code needed to generate, install, and (for an executable +work) run the object code and to modify the work, including scripts to +control those activities. However, it does not include the work's +System Libraries, or general-purpose tools or generally available free +programs which are used unmodified in performing those activities but +which are not part of the work. For example, Corresponding Source +includes interface definition files associated with source files for +the work, and the source code for shared libraries and dynamically +linked subprograms that the work is specifically designed to require, +such as by intimate data communication or control flow between those +subprograms and other parts of the work. + + The Corresponding Source need not include anything that users +can regenerate automatically from other parts of the Corresponding +Source. + + The Corresponding Source for a work in source code form is that +same work. + + 2. Basic Permissions. + + All rights granted under this License are granted for the term of +copyright on the Program, and are irrevocable provided the stated +conditions are met. This License explicitly affirms your unlimited +permission to run the unmodified Program. The output from running a +covered work is covered by this License only if the output, given its +content, constitutes a covered work. This License acknowledges your +rights of fair use or other equivalent, as provided by copyright law. + + You may make, run and propagate covered works that you do not +convey, without conditions so long as your license otherwise remains +in force. You may convey covered works to others for the sole purpose +of having them make modifications exclusively for you, or provide you +with facilities for running those works, provided that you comply with +the terms of this License in conveying all material for which you do +not control copyright. Those thus making or running the covered works +for you must do so exclusively on your behalf, under your direction +and control, on terms that prohibit them from making any copies of +your copyrighted material outside their relationship with you. + + Conveying under any other circumstances is permitted solely under +the conditions stated below. Sublicensing is not allowed; section 10 +makes it unnecessary. + + 3. Protecting Users' Legal Rights From Anti-Circumvention Law. + + No covered work shall be deemed part of an effective technological +measure under any applicable law fulfilling obligations under article +11 of the WIPO copyright treaty adopted on 20 December 1996, or +similar laws prohibiting or restricting circumvention of such +measures. + + When you convey a covered work, you waive any legal power to forbid +circumvention of technological measures to the extent such circumvention +is effected by exercising rights under this License with respect to +the covered work, and you disclaim any intention to limit operation or +modification of the work as a means of enforcing, against the work's +users, your or third parties' legal rights to forbid circumvention of +technological measures. + + 4. Conveying Verbatim Copies. + + You may convey verbatim copies of the Program's source code as you +receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy an appropriate copyright notice; +keep intact all notices stating that this License and any +non-permissive terms added in accord with section 7 apply to the code; +keep intact all notices of the absence of any warranty; and give all +recipients a copy of this License along with the Program. + + You may charge any price or no price for each copy that you convey, +and you may offer support or warranty protection for a fee. + + 5. Conveying Modified Source Versions. + + You may convey a work based on the Program, or the modifications to +produce it from the Program, in the form of source code under the +terms of section 4, provided that you also meet all of these conditions: + + a) The work must carry prominent notices stating that you modified + it, and giving a relevant date. + + b) The work must carry prominent notices stating that it is + released under this License and any conditions added under section + 7. This requirement modifies the requirement in section 4 to + "keep intact all notices". + + c) You must license the entire work, as a whole, under this + License to anyone who comes into possession of a copy. This + License will therefore apply, along with any applicable section 7 + additional terms, to the whole of the work, and all its parts, + regardless of how they are packaged. This License gives no + permission to license the work in any other way, but it does not + invalidate such permission if you have separately received it. + + d) If the work has interactive user interfaces, each must display + Appropriate Legal Notices; however, if the Program has interactive + interfaces that do not display Appropriate Legal Notices, your + work need not make them do so. + + A compilation of a covered work with other separate and independent +works, which are not by their nature extensions of the covered work, +and which are not combined with it such as to form a larger program, +in or on a volume of a storage or distribution medium, is called an +"aggregate" if the compilation and its resulting copyright are not +used to limit the access or legal rights of the compilation's users +beyond what the individual works permit. Inclusion of a covered work +in an aggregate does not cause this License to apply to the other +parts of the aggregate. + + 6. Conveying Non-Source Forms. + + You may convey a covered work in object code form under the terms +of sections 4 and 5, provided that you also convey the +machine-readable Corresponding Source under the terms of this License, +in one of these ways: + + a) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by the + Corresponding Source fixed on a durable physical medium + customarily used for software interchange. + + b) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by a + written offer, valid for at least three years and valid for as + long as you offer spare parts or customer support for that product + model, to give anyone who possesses the object code either (1) a + copy of the Corresponding Source for all the software in the + product that is covered by this License, on a durable physical + medium customarily used for software interchange, for a price no + more than your reasonable cost of physically performing this + conveying of source, or (2) access to copy the + Corresponding Source from a network server at no charge. + + c) Convey individual copies of the object code with a copy of the + written offer to provide the Corresponding Source. This + alternative is allowed only occasionally and noncommercially, and + only if you received the object code with such an offer, in accord + with subsection 6b. + + d) Convey the object code by offering access from a designated + place (gratis or for a charge), and offer equivalent access to the + Corresponding Source in the same way through the same place at no + further charge. You need not require recipients to copy the + Corresponding Source along with the object code. If the place to + copy the object code is a network server, the Corresponding Source + may be on a different server (operated by you or a third party) + that supports equivalent copying facilities, provided you maintain + clear directions next to the object code saying where to find the + Corresponding Source. Regardless of what server hosts the + Corresponding Source, you remain obligated to ensure that it is + available for as long as needed to satisfy these requirements. + + e) Convey the object code using peer-to-peer transmission, provided + you inform other peers where the object code and Corresponding + Source of the work are being offered to the general public at no + charge under subsection 6d. + + A separable portion of the object code, whose source code is excluded +from the Corresponding Source as a System Library, need not be +included in conveying the object code work. + + A "User Product" is either (1) a "consumer product", which means any +tangible personal property which is normally used for personal, family, +or household purposes, or (2) anything designed or sold for incorporation +into a dwelling. In determining whether a product is a consumer product, +doubtful cases shall be resolved in favor of coverage. For a particular +product received by a particular user, "normally used" refers to a +typical or common use of that class of product, regardless of the status +of the particular user or of the way in which the particular user +actually uses, or expects or is expected to use, the product. A product +is a consumer product regardless of whether the product has substantial +commercial, industrial or non-consumer uses, unless such uses represent +the only significant mode of use of the product. + + "Installation Information" for a User Product means any methods, +procedures, authorization keys, or other information required to install +and execute modified versions of a covered work in that User Product from +a modified version of its Corresponding Source. The information must +suffice to ensure that the continued functioning of the modified object +code is in no case prevented or interfered with solely because +modification has been made. + + If you convey an object code work under this section in, or with, or +specifically for use in, a User Product, and the conveying occurs as +part of a transaction in which the right of possession and use of the +User Product is transferred to the recipient in perpetuity or for a +fixed term (regardless of how the transaction is characterized), the +Corresponding Source conveyed under this section must be accompanied +by the Installation Information. But this requirement does not apply +if neither you nor any third party retains the ability to install +modified object code on the User Product (for example, the work has +been installed in ROM). + + The requirement to provide Installation Information does not include a +requirement to continue to provide support service, warranty, or updates +for a work that has been modified or installed by the recipient, or for +the User Product in which it has been modified or installed. Access to a +network may be denied when the modification itself materially and +adversely affects the operation of the network or violates the rules and +protocols for communication across the network. + + Corresponding Source conveyed, and Installation Information provided, +in accord with this section must be in a format that is publicly +documented (and with an implementation available to the public in +source code form), and must require no special password or key for +unpacking, reading or copying. + + 7. Additional Terms. + + "Additional permissions" are terms that supplement the terms of this +License by making exceptions from one or more of its conditions. +Additional permissions that are applicable to the entire Program shall +be treated as though they were included in this License, to the extent +that they are valid under applicable law. If additional permissions +apply only to part of the Program, that part may be used separately +under those permissions, but the entire Program remains governed by +this License without regard to the additional permissions. + + When you convey a copy of a covered work, you may at your option +remove any additional permissions from that copy, or from any part of +it. (Additional permissions may be written to require their own +removal in certain cases when you modify the work.) You may place +additional permissions on material, added by you to a covered work, +for which you have or can give appropriate copyright permission. + + Notwithstanding any other provision of this License, for material you +add to a covered work, you may (if authorized by the copyright holders of +that material) supplement the terms of this License with terms: + + a) Disclaiming warranty or limiting liability differently from the + terms of sections 15 and 16 of this License; or + + b) Requiring preservation of specified reasonable legal notices or + author attributions in that material or in the Appropriate Legal + Notices displayed by works containing it; or + + c) Prohibiting misrepresentation of the origin of that material, or + requiring that modified versions of such material be marked in + reasonable ways as different from the original version; or + + d) Limiting the use for publicity purposes of names of licensors or + authors of the material; or + + e) Declining to grant rights under trademark law for use of some + trade names, trademarks, or service marks; or + + f) Requiring indemnification of licensors and authors of that + material by anyone who conveys the material (or modified versions of + it) with contractual assumptions of liability to the recipient, for + any liability that these contractual assumptions directly impose on + those licensors and authors. + + All other non-permissive additional terms are considered "further +restrictions" within the meaning of section 10. If the Program as you +received it, or any part of it, contains a notice stating that it is +governed by this License along with a term that is a further +restriction, you may remove that term. If a license document contains +a further restriction but permits relicensing or conveying under this +License, you may add to a covered work material governed by the terms +of that license document, provided that the further restriction does +not survive such relicensing or conveying. + + If you add terms to a covered work in accord with this section, you +must place, in the relevant source files, a statement of the +additional terms that apply to those files, or a notice indicating +where to find the applicable terms. + + Additional terms, permissive or non-permissive, may be stated in the +form of a separately written license, or stated as exceptions; +the above requirements apply either way. + + 8. Termination. + + You may not propagate or modify a covered work except as expressly +provided under this License. Any attempt otherwise to propagate or +modify it is void, and will automatically terminate your rights under +this License (including any patent licenses granted under the third +paragraph of section 11). + + However, if you cease all violation of this License, then your +license from a particular copyright holder is reinstated (a) +provisionally, unless and until the copyright holder explicitly and +finally terminates your license, and (b) permanently, if the copyright +holder fails to notify you of the violation by some reasonable means +prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + + Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, you do not qualify to receive new licenses for the same +material under section 10. + + 9. Acceptance Not Required for Having Copies. + + You are not required to accept this License in order to receive or +run a copy of the Program. Ancillary propagation of a covered work +occurring solely as a consequence of using peer-to-peer transmission +to receive a copy likewise does not require acceptance. However, +nothing other than this License grants you permission to propagate or +modify any covered work. These actions infringe copyright if you do +not accept this License. Therefore, by modifying or propagating a +covered work, you indicate your acceptance of this License to do so. + + 10. Automatic Licensing of Downstream Recipients. + + Each time you convey a covered work, the recipient automatically +receives a license from the original licensors, to run, modify and +propagate that work, subject to this License. You are not responsible +for enforcing compliance by third parties with this License. + + An "entity transaction" is a transaction transferring control of an +organization, or substantially all assets of one, or subdividing an +organization, or merging organizations. If propagation of a covered +work results from an entity transaction, each party to that +transaction who receives a copy of the work also receives whatever +licenses to the work the party's predecessor in interest had or could +give under the previous paragraph, plus a right to possession of the +Corresponding Source of the work from the predecessor in interest, if +the predecessor has it or can get it with reasonable efforts. + + You may not impose any further restrictions on the exercise of the +rights granted or affirmed under this License. For example, you may +not impose a license fee, royalty, or other charge for exercise of +rights granted under this License, and you may not initiate litigation +(including a cross-claim or counterclaim in a lawsuit) alleging that +any patent claim is infringed by making, using, selling, offering for +sale, or importing the Program or any portion of it. + + 11. Patents. + + A "contributor" is a copyright holder who authorizes use under this +License of the Program or a work on which the Program is based. The +work thus licensed is called the contributor's "contributor version". + + A contributor's "essential patent claims" are all patent claims +owned or controlled by the contributor, whether already acquired or +hereafter acquired, that would be infringed by some manner, permitted +by this License, of making, using, or selling its contributor version, +but do not include claims that would be infringed only as a +consequence of further modification of the contributor version. For +purposes of this definition, "control" includes the right to grant +patent sublicenses in a manner consistent with the requirements of +this License. + + Each contributor grants you a non-exclusive, worldwide, royalty-free +patent license under the contributor's essential patent claims, to +make, use, sell, offer for sale, import and otherwise run, modify and +propagate the contents of its contributor version. + + In the following three paragraphs, a "patent license" is any express +agreement or commitment, however denominated, not to enforce a patent +(such as an express permission to practice a patent or covenant not to +sue for patent infringement). To "grant" such a patent license to a +party means to make such an agreement or commitment not to enforce a +patent against the party. + + If you convey a covered work, knowingly relying on a patent license, +and the Corresponding Source of the work is not available for anyone +to copy, free of charge and under the terms of this License, through a +publicly available network server or other readily accessible means, +then you must either (1) cause the Corresponding Source to be so +available, or (2) arrange to deprive yourself of the benefit of the +patent license for this particular work, or (3) arrange, in a manner +consistent with the requirements of this License, to extend the patent +license to downstream recipients. "Knowingly relying" means you have +actual knowledge that, but for the patent license, your conveying the +covered work in a country, or your recipient's use of the covered work +in a country, would infringe one or more identifiable patents in that +country that you have reason to believe are valid. + + If, pursuant to or in connection with a single transaction or +arrangement, you convey, or propagate by procuring conveyance of, a +covered work, and grant a patent license to some of the parties +receiving the covered work authorizing them to use, propagate, modify +or convey a specific copy of the covered work, then the patent license +you grant is automatically extended to all recipients of the covered +work and works based on it. + + A patent license is "discriminatory" if it does not include within +the scope of its coverage, prohibits the exercise of, or is +conditioned on the non-exercise of one or more of the rights that are +specifically granted under this License. You may not convey a covered +work if you are a party to an arrangement with a third party that is +in the business of distributing software, under which you make payment +to the third party based on the extent of your activity of conveying +the work, and under which the third party grants, to any of the +parties who would receive the covered work from you, a discriminatory +patent license (a) in connection with copies of the covered work +conveyed by you (or copies made from those copies), or (b) primarily +for and in connection with specific products or compilations that +contain the covered work, unless you entered into that arrangement, +or that patent license was granted, prior to 28 March 2007. + + Nothing in this License shall be construed as excluding or limiting +any implied license or other defenses to infringement that may +otherwise be available to you under applicable patent law. + + 12. No Surrender of Others' Freedom. + + If conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot convey a +covered work so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you may +not convey it at all. For example, if you agree to terms that obligate you +to collect a royalty for further conveying from those to whom you convey +the Program, the only way you could satisfy both those terms and this +License would be to refrain entirely from conveying the Program. + + 13. Use with the GNU Affero General Public License. + + Notwithstanding any other provision of this License, you have +permission to link or combine any covered work with a work licensed +under version 3 of the GNU Affero General Public License into a single +combined work, and to convey the resulting work. The terms of this +License will continue to apply to the part which is the covered work, +but the special requirements of the GNU Affero General Public License, +section 13, concerning interaction through a network will apply to the +combination as such. + + 14. Revised Versions of this License. + + The Free Software Foundation may publish revised and/or new versions of +the GNU General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + + Each version is given a distinguishing version number. If the +Program specifies that a certain numbered version of the GNU General +Public License "or any later version" applies to it, you have the +option of following the terms and conditions either of that numbered +version or of any later version published by the Free Software +Foundation. If the Program does not specify a version number of the +GNU General Public License, you may choose any version ever published +by the Free Software Foundation. + + If the Program specifies that a proxy can decide which future +versions of the GNU General Public License can be used, that proxy's +public statement of acceptance of a version permanently authorizes you +to choose that version for the Program. + + Later license versions may give you additional or different +permissions. However, no additional obligations are imposed on any +author or copyright holder as a result of your choosing to follow a +later version. + + 15. Disclaimer of Warranty. + + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY +APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY +OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, +THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM +IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF +ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. Limitation of Liability. + + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS +THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY +GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE +USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF +DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD +PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), +EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF +SUCH DAMAGES. + + 17. Interpretation of Sections 15 and 16. + + If the disclaimer of warranty and limitation of liability provided +above cannot be given local legal effect according to their terms, +reviewing courts shall apply local law that most closely approximates +an absolute waiver of all civil liability in connection with the +Program, unless a warranty or assumption of liability accompanies a +copy of the Program in return for a fee. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +state the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software: you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation, either version 3 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program. If not, see . + +Also add information on how to contact you by electronic and paper mail. + + If the program does terminal interaction, make it output a short +notice like this when it starts in an interactive mode: + + Copyright (C) + This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, your program's commands +might be different; for a GUI interface, you would use an "about box". + + You should also get your employer (if you work as a programmer) or school, +if any, to sign a "copyright disclaimer" for the program, if necessary. +For more information on this, and how to apply and follow the GNU GPL, see +. + + The GNU General Public License does not permit incorporating your program +into proprietary programs. If your program is a subroutine library, you +may consider it more useful to permit linking proprietary applications with +the library. If this is what you want to do, use the GNU Lesser General +Public License instead of this License. But first, please read +. + + GNU LESSER GENERAL PUBLIC LICENSE + Version 3, 29 June 2007 + + Copyright (C) 2007 Free Software Foundation, Inc. + Everyone is permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed. + + + This version of the GNU Lesser General Public License incorporates +the terms and conditions of version 3 of the GNU General Public +License, supplemented by the additional permissions listed below. + + 0. Additional Definitions. + + As used herein, "this License" refers to version 3 of the GNU Lesser +General Public License, and the "GNU GPL" refers to version 3 of the GNU +General Public License. + + "The Library" refers to a covered work governed by this License, +other than an Application or a Combined Work as defined below. + + An "Application" is any work that makes use of an interface provided +by the Library, but which is not otherwise based on the Library. +Defining a subclass of a class defined by the Library is deemed a mode +of using an interface provided by the Library. + + A "Combined Work" is a work produced by combining or linking an +Application with the Library. The particular version of the Library +with which the Combined Work was made is also called the "Linked +Version". + + The "Minimal Corresponding Source" for a Combined Work means the +Corresponding Source for the Combined Work, excluding any source code +for portions of the Combined Work that, considered in isolation, are +based on the Application, and not on the Linked Version. + + The "Corresponding Application Code" for a Combined Work means the +object code and/or source code for the Application, including any data +and utility programs needed for reproducing the Combined Work from the +Application, but excluding the System Libraries of the Combined Work. + + 1. Exception to Section 3 of the GNU GPL. + + You may convey a covered work under sections 3 and 4 of this License +without being bound by section 3 of the GNU GPL. + + 2. Conveying Modified Versions. + + If you modify a copy of the Library, and, in your modifications, a +facility refers to a function or data to be supplied by an Application +that uses the facility (other than as an argument passed when the +facility is invoked), then you may convey a copy of the modified +version: + + a) under this License, provided that you make a good faith effort to + ensure that, in the event an Application does not supply the + function or data, the facility still operates, and performs + whatever part of its purpose remains meaningful, or + + b) under the GNU GPL, with none of the additional permissions of + this License applicable to that copy. + + 3. Object Code Incorporating Material from Library Header Files. + + The object code form of an Application may incorporate material from +a header file that is part of the Library. You may convey such object +code under terms of your choice, provided that, if the incorporated +material is not limited to numerical parameters, data structure +layouts and accessors, or small macros, inline functions and templates +(ten or fewer lines in length), you do both of the following: + + a) Give prominent notice with each copy of the object code that the + Library is used in it and that the Library and its use are + covered by this License. + + b) Accompany the object code with a copy of the GNU GPL and this license + document. + + 4. Combined Works. + + You may convey a Combined Work under terms of your choice that, +taken together, effectively do not restrict modification of the +portions of the Library contained in the Combined Work and reverse +engineering for debugging such modifications, if you also do each of +the following: + + a) Give prominent notice with each copy of the Combined Work that + the Library is used in it and that the Library and its use are + covered by this License. + + b) Accompany the Combined Work with a copy of the GNU GPL and this license + document. + + c) For a Combined Work that displays copyright notices during + execution, include the copyright notice for the Library among + these notices, as well as a reference directing the user to the + copies of the GNU GPL and this license document. + + d) Do one of the following: + + 0) Convey the Minimal Corresponding Source under the terms of this + License, and the Corresponding Application Code in a form + suitable for, and under terms that permit, the user to + recombine or relink the Application with a modified version of + the Linked Version to produce a modified Combined Work, in the + manner specified by section 6 of the GNU GPL for conveying + Corresponding Source. + + 1) Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that (a) uses at run time + a copy of the Library already present on the user's computer + system, and (b) will operate properly with a modified version + of the Library that is interface-compatible with the Linked + Version. + + e) Provide Installation Information, but only if you would otherwise + be required to provide such information under section 6 of the + GNU GPL, and only to the extent that such information is + necessary to install and execute a modified version of the + Combined Work produced by recombining or relinking the + Application with a modified version of the Linked Version. (If + you use option 4d0, the Installation Information must accompany + the Minimal Corresponding Source and Corresponding Application + Code. If you use option 4d1, you must provide the Installation + Information in the manner specified by section 6 of the GNU GPL + for conveying Corresponding Source.) + + 5. Combined Libraries. + + You may place library facilities that are a work based on the +Library side by side in a single library together with other library +facilities that are not Applications and are not covered by this +License, and convey such a combined library under terms of your +choice, if you do both of the following: + + a) Accompany the combined library with a copy of the same work based + on the Library, uncombined with any other library facilities, + conveyed under the terms of this License. + + b) Give prominent notice with the combined library that part of it + is a work based on the Library, and explaining where to find the + accompanying uncombined form of the same work. + + 6. Revised Versions of the GNU Lesser General Public License. + + The Free Software Foundation may publish revised and/or new versions +of the GNU Lesser General Public License from time to time. Such new +versions will be similar in spirit to the present version, but may +differ in detail to address new problems or concerns. + + Each version is given a distinguishing version number. If the +Library as you received it specifies that a certain numbered version +of the GNU Lesser General Public License "or any later version" +applies to it, you have the option of following the terms and +conditions either of that published version or of any later version +published by the Free Software Foundation. If the Library as you +received it does not specify a version number of the GNU Lesser +General Public License, you may choose any version of the GNU Lesser +General Public License ever published by the Free Software Foundation. + + If the Library as you received it specifies that a proxy can decide +whether future versions of the GNU Lesser General Public License shall +apply, that proxy's public statement of acceptance of any version is +permanent authorization for you to choose that version for the +Library. + diff --git a/libusb/lib/bcc/libusb.lib b/libusb/lib/bcc/libusb.lib new file mode 100644 index 0000000000000000000000000000000000000000..86c0cedeb7b7fcf0a5bcf1c6d48af676b4095c76 GIT binary patch literal 6144 zcmdT|TZmOv82-l~(wR}mQOC=8Nz5|KB*jcZEv1V}raepswL5dpnlro3?0wpMAIlzW zM;CSqNkmczkycPd*aSZGAYo+?J`^Z~4;4|-LlpMVQv|K`uiL-&<;+t-=fTVR|NVXc zZLRgM|8hUT9Dpl8{(etq!%VLek9wn>)?;48YK_TkEx?;S`Q_f0Kg#vit!=bg{muvM z@HBu#0j5JR&*H@_>9oCCd@!iLoZW`7wy~S#gH(qNc_c-ye>l78^VMVVRz_br$D0{=0?ao%A zm1K#cOqaHC#p4+EuN z9YWDHiZVl>NYx(^z}Pe92Mu22am?bgjy*&`kjg!UDR%3HN+=@M3l)~u zi>~jnh%s4>w>tT>>l7RFX+<5K4lwo6WQlTrrGsbJ3wTzv%i_(0LCl8`HdtJb{B{yX zQML*5QYNFgb3}gJPk%AkV%MZs!?F^5Z}gzYf<`;!8|abjKIEE8kMb@p@>0mpj15k_ z;w18e=88hR^CI#xB*k| z!k7ariv2K{bn2Z5Cu36Z=OG3 ztP%5zm46;3-0h8}{CTZP{=8zC=hx@24p-2={Rb!iL_k?E|3r39<-dqGa=rp@qzm52 z>k2Pl4?$ZcW|gxatR+fJv7LG_0DE$wz+I6pgdwLMVit*uglFROY#UZWm7Frpr!`<9 zjua@<<*>AZPdV~Mb}!OSp+?!4l(Q?qqtu90pU>E7M4fhmP2IS2KD#o?gy*v>zCht2 z9fn29Ki7T4o*uj0{^iMe<<-qi(smu5O#XPXAJ+ zMcJ``s#1I>XGFRf7UF*B1iA&V*X_624%{5o8kBc|*ePW&X9#Dy0+v_uDVM*`_95+* zij;j>6}tjGD~7#PT)TtThnew@~Qw?BpJ;3{*4syM-FRO=I z;U4)CoDswtWvj*Gw_M|m+_i8~jX}r+;U*{_1r0%Aq}3-f@^Af`!yI{+K)*#&9NZ%6 z0amxge;+t@7~Yck7x|GBldUQ?gZ()bYd0H`lHXCONL?F z#v=gl0lWslyIp__awKeS&|g9Aa(Y|+Sse87VWAxj)Rmmf6dne(ren$13n4r zG%3`cI!LGW$T2OQtZgXpj6ADt6CL!&bjZ0v*PpdYL1((cY#)2ZZPza8>JhP`?bdg> UGtg9zf)2V|b2E6={#(C)0D_}*2LJ#7 literal 0 HcmV?d00001 diff --git a/libusb/lib/dynamic/libusb_dyn.c b/libusb/lib/dynamic/libusb_dyn.c new file mode 100644 index 0000000..f0fac9a --- /dev/null +++ b/libusb/lib/dynamic/libusb_dyn.c @@ -0,0 +1,497 @@ +/* LIBUSB-WIN32, Generic Windows USB Library + * Copyright (c) 2002-2005 Stephan Meyer + * + * This library is free software; you can redistribute it and/or + * modify it under the terms of the GNU Lesser General Public + * License as published by the Free Software Foundation; either + * version 2 of the License, or (at your option) any later version. + * + * This library is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

+============================================== +* Official release. + +* Removed ISO maximum transfer size restrictions/transfer spltting. + +* Fixed inf-wizard device notification issue. + +V1.2.5.0 (07/23/2011) +============================================== +* Official release. + +V1.2.4.9 (07/13/2011) - SNAPSHOT RELEASE +============================================== +* Updated GCC lib file 'libusb.a' + +V1.2.4.8 (07/12/2011) - SNAPSHOT RELEASE +============================================== +* Added new public api function 'usb_reset_ex'. This is an extended + device reset function which allows developers to specify a port reset, a + port cycle, or both. + +* Added new public defines 'USB_RESET_TYPE_XXX' for 'usb_reset_ex' + function. + +V1.2.4.7 (07/02/2011) - SNAPSHOT RELEASE +============================================== +* Sync transfers which specify a zero (0) timeout are now considered to be + INFINITE. + +V1.2.4.6 (05/12/2011) - SNAPSHOT RELEASE +============================================== +* Added device interface registration. This provides identical + functionality to the "DeviceInterfaceGUIDs" supported by WinUSB and + libusbK. A device interface guid can be specified in the .inf file. They + can be used to quickly locate a usb device or set of USB devices using + the setup api as well as device notification registration. + +* New IOCTL codes added to for native libusbK/WinUSB compatibility. + NOTE: These IOCTLs are currently used only by libusbK.dll. + o LIBUSB_IOCTL_QUERY_DEVICE_INFORMATION + o LIBUSB_IOCTL_SET_PIPE_POLICY + o LIBUSB_IOCTL_GET_PIPE_POLICY + o LIBUSB_IOCTL_SET_POWER_POLICY + o LIBUSB_IOCTL_GET_POWER_POLICY + o LIBUSB_IOCTL_CONTROL_WRITE + o LIBUSB_IOCTL_CONTROL_READ + o LIBUSB_IOCTL_FLUSH_PIPE + o LIBUSBK_IOCTL_CLAIM_INTERFACE + o LIBUSBK_IOCTL_RELEASE_INTERFACE + o LIBUSBK_IOCTL_RELEASE_ALL_INTERFACES + o LIBUSBK_IOCTL_SET_INTERFACE + o LIBUSBK_IOCTL_GET_INTERFACE + +* Renamed main header file (usb.h) to lusb0_usb.h. This eliminates + conflicts with the main WDK usb include as well as making the + libusb-win32 header more distinguishable from other usb library header + files. + +* Added device descriptor caching and active/first config descriptor + caching. Descriptor caching prevents unnecessary control requests from + interrupting devices that could potentially be in-use. It also makes + libusb0.sys more compliant with usb libraries targeting platform where + descriptor caching is done automatically. (linux/mac) + +* Upgraded to libwdi v1.1.1 + o Zadig UI improvements + o wdi-simple now handles certificate related operations + o New NSIS (Nullsoft Scriptable Install System) script sample + o improved INNO Setup script sample + o libusbK support + o autogeneration and self-signing of a .cat file, to prevent further security + prompts during driver installation on Vista and later. + for more information, see http://libwdi-cps.akeo.ie + o disable restore point creation during installation + o Visual Studio 2010 support and overall MS file cleanup + o use of the Kerberos/e2fsprogs parser in Zadig instead of libconfig + +V1.2.4.0 (04/11/2011) +======================= +* Removed get configuration request from the core driver + set_configuration function. This caused problems with + some non-compliant usb devices. + +* Added device descriptor dump to test applications. + +V1.2.3.0 (03/16/2011) +======================= +* Fixed bug-id 3117686 reported by Tim Schuerewegen. + +* Added LIBUSB_IOCTL_GET_OBJECT_NAME. This new IOCTL code retrieves object + from the driver. The only valid object name index is 0. Index 0 is + returns the devices plug and play registry key pathname. + +* Removed maximum timeout restriction for vendor class requests. + +V1.2.2.0 (10/02/2010) +======================= +* Added install-filter-win.exe. A gui installer for device filters. + +* Added new libusb0.dll function usb_install_np_rundll(). This function + is designed for rundll32.exe and takes the same parameters as + install-filter.exe. + +* Updated install-filter.exe. This application has several new features. + Type "install-filter --help" for more details. + +* Updated libusb-win32-devel-filter package. This package is once again + available for download as a setup.exe. + +* Updated libusb-win32 "bin" package format. inf-wizard.exe has been moved + up one directory. + +* Updated driver_installer_template.iss example. This is an Inno Setup + Script showing how to create your own setup.exe for installing your + application and driver. + +* Fixed missing byte order marker in inf-wizard.exe .inf files. (libwdi) + +* Fixed auto-configuration issue when there is more than one driver in the + stack. + +* Fixed BSOD when using the filter driver with devices that are auto + suspended by other drivers in the stack. + +* Fixed BSOD for devices with endpoints that have '0' for wMaxPacketSize. + +* Fixed BSOD when cancelling large transfers on high speed devices. + + +V1.2.1.0 (07/28/2010) +======================= +* Updated bulk.c to include async i/o example code. + +* Fixed usb_install_driver_np() issue with inf-wizard generated infs. + +* Fixed inf2cat.exe issue with inf-wizard generated infs. + +* Added 'Install Now' feature to inf-wizard. (libwdi) + +* Added embedded libusb-win32 binaries to inf-wizard. (libwdi) + +* Added libwdi (http://www.libusb.org/wiki/libwdi) to inf-wizard. + +* Added get cached configuration request to usb_open(). This is a new + control code that involves no device i/o and allows + usb_set_configuration() to be omitted if the driver has already + configured it. + +* Fixed set_configuration() failure for devices that do not properly + support get_configuration(). + +V1.2.0.0 (07/07/2010) +======================= +* First signed driver release! The libusb-win32 kernel driver (libusb0.sys) + can now be used on x64 Windows machines that require signed drivers. + +* Fixed 2128187 reported by Tim Green. usb_get_descriptor() can fail + because the given buffer of 8 bytes is too small. + +* Fixed 2928293 reported by Tim Green. Sometimes the call to + usb_fetch_and_parse_descriptors() in usb_find_devices() can fail. This + patch moves the LIST_ADD to after a successful read of the device's + configuration descriptors. + +* Fixed issue causing libusb-win32 to not act as power policy owner + when it should. + +* Fixed issue in which on rare occasion, a libusb-win32 filter device could + run as a "normal" device. + +* Fixed filter driver issue for device using wudfr.sys. + +* Added large transfer splitting to driver (bulk, int, iso). NOTE: + The dll continues to break transfers in the same manner it always has. + + +V1.1.14.3 (06/12/2010) +======================= +* Remove get_configuration() request from usb_open(). This caused claim + interface to fail when used as a filter driver. + +V1.1.14.0 (06/01/2010) +======================= +* Updated logging functions and standardized log message display format. + +* Updated inf-wizard to use the new directory format for the libusb-win32 + binaries. + +* Updated package directories to reflect the winddk BUILDARCH env variable. + (i64 := ia64, x64 := amd64) + +* Added request to get the current configuration in usb_open(). + +* Fixed 2960644 (reported by farthen) crash on shutdown with x64 based + systems while using inf files for each libusb device. + +* Added additional log message only included in debug/chk builds. + +* Updated default log levels to highest verbose level for debug builds. + +* Added test signing support to the libusb-win32 make.cmd. This allows + libusb0.sys and libusb0.dll to be signed with a digital signature. + (see make.cmd for mmore details) + +* Added MSVC 2008 project files + +* Moved version defines to an include file (libusb_version.h) + This file is generated from libusb_version_h.in with "make.cmd makever" + +* Removed all "dist" commands from cyg/mingw makefile. Instead use "make.cmd" + in the "ddk_make" directory. + +* Fixed filter setup not running in 64bit mode + +* Fixed 64bit inf-wizard, testlibusb-win builds + +* Added set initial config value #1 when the driver is not a filter. + optionally, the initial configuration value can be specified in the inf + file: HKR,,"InitialConfigValue",0x00010001, + +* Added support for querying device registry keys + (LIBUSB_IOCTL_GET_CUSTOM_REG_PROPERTY) + +* Added support for querying device properties + (LIBUSB_IOCTL_GET_DEVICE_PROPERTY) + +* Fixed possible race condition in kernel add_device() + +* Updated default ddk build version number to 1.1.14.0 to facilitate + Microsoft WHQL submission. + +* Added DDK build distribution system. Official libusb-win32 releases + (after 0.1.12.2) are built using Microsoft's WinDDK.

usbconfig.h to configure how each + USB descriptor should be handled. It is now possible to provide descriptor + data in Flash, RAM or dynamically at runtime. + - STALL is now a status in usbTxLen* instead of a message. We can now conform + to the spec and leave the stall status pending until it is cleared. + - Made usbTxPacketCnt1 and usbTxPacketCnt3 public. This allows the + application code to reset data toggling on interrupt pipes. + +* Release 2006-07-18 + + - Added an #if !defined __ASSEMBLER__ to the warning in usbdrv.h. This fixes + an assembler error. + - usbDeviceDisconnect() takes pull-up resistor to high impedance now. + +* Release 2007-02-01 + + - Merged in some code size improvements from usbtiny (thanks to Dick + Streefland for these optimizations!) + - Special alignment requirement for usbRxBuf not required any more. Thanks + again to Dick Streefland for this hint! + - Reverted to "#warning" instead of unused static variables -- new versions + of IAR CC should handle this directive. + - Changed Open Source license to GNU GPL v2 in order to make linking against + other free libraries easier. We no longer require publication of the + circuit diagrams, but we STRONGLY encourage it. If you improve the driver + itself, PLEASE grant us a royalty free license to your changes for our + commercial license. + +* Release 2007-03-29 + + - New configuration option "USB_PUBLIC" in usbconfig.h. + - Set USB version number to 1.10 instead of 1.01. + - Code used USB_CFG_DESCR_PROPS_STRING_DEVICE and + USB_CFG_DESCR_PROPS_STRING_PRODUCT inconsistently. Changed all occurrences + to USB_CFG_DESCR_PROPS_STRING_PRODUCT. + - New assembler module for 16.5 MHz RC oscillator clock with PLL in receiver + code. + - New assembler module for 16 MHz crystal. + - usbdrvasm.S contains common code only, clock-specific parts have been moved + to usbdrvasm12.S, usbdrvasm16.S and usbdrvasm165.S respectively. + +* Release 2007-06-25 + + - 16 MHz module: Do SE0 check in stuffed bits as well. + +* Release 2007-07-07 + + - Define hi8(x) for IAR compiler to limit result to 8 bits. This is necessary + for negative values. + - Added 15 MHz module contributed by V. Bosch. + - Interrupt vector name can now be configured. This is useful if somebody + wants to use a different hardware interrupt than INT0. + +* Release 2007-08-07 + + - Moved handleIn3 routine in usbdrvasm16.S so that relative jump range is + not exceeded. + - More config options: USB_RX_USER_HOOK(), USB_INITIAL_DATATOKEN, + USB_COUNT_SOF + - USB_INTR_PENDING can now be a memory address, not just I/O + +* Release 2007-09-19 + + - Split out common parts of assembler modules into separate include file + - Made endpoint numbers configurable so that given interface definitions + can be matched. See USB_CFG_EP3_NUMBER in usbconfig-prototype.h. + - Store endpoint number for interrupt/bulk-out so that usbFunctionWriteOut() + can handle any number of endpoints. + - Define usbDeviceConnect() and usbDeviceDisconnect() even if no + USB_CFG_PULLUP_IOPORTNAME is defined. Directly set D+ and D- to 0 in this + case. + +* Release 2007-12-01 + + - Optimize usbDeviceConnect() and usbDeviceDisconnect() for less code size + when USB_CFG_PULLUP_IOPORTNAME is not defined. + +* Release 2007-12-13 + + - Renamed all include-only assembler modules from *.S to *.inc so that + people don't add them to their project sources. + - Distribute leap bits in tx loop more evenly for 16 MHz module. + - Use "macro" and "endm" instead of ".macro" and ".endm" for IAR + - Avoid compiler warnings for constant expr range by casting some values in + USB descriptors. + +* Release 2008-01-21 + + - Fixed bug in 15 and 16 MHz module where the new address set with + SET_ADDRESS was already accepted at the next NAK or ACK we send, not at + the next data packet we send. This caused problems when the host polled + too fast. Thanks to Alexander Neumann for his help and patience debugging + this issue! + +* Release 2008-02-05 + + - Fixed bug in 16.5 MHz module where a register was used in the interrupt + handler before it was pushed. This bug was introduced with version + 2007-09-19 when common parts were moved to a separate file. + - Optimized CRC routine (thanks to Reimar Doeffinger). + +* Release 2008-02-16 + + - Removed outdated IAR compatibility stuff (code sections). + - Added hook macros for USB_RESET_HOOK() and USB_SET_ADDRESS_HOOK(). + - Added optional routine usbMeasureFrameLength() for calibration of the + internal RC oscillator. + +* Release 2008-02-28 + + - USB_INITIAL_DATATOKEN defaults to USBPID_DATA1 now, which means that we + start with sending USBPID_DATA0. + - Changed defaults in usbconfig-prototype.h + - Added free USB VID/PID pair for MIDI class devices + - Restructured AVR-USB as separate package, not part of PowerSwitch any more. + +* Release 2008-04-18 + + - Restructured usbdrv.c so that it is easier to read and understand. + - Better code optimization with gcc 4. + - If a second interrupt in endpoint is enabled, also add it to config + descriptor. + - Added config option for long transfers (above 254 bytes), see + USB_CFG_LONG_TRANSFERS in usbconfig.h. + - Added 20 MHz module contributed by Jeroen Benschop. + +* Release 2008-05-13 + + - Fixed bug in libs-host/hiddata.c function usbhidGetReport(): length + was not incremented, pointer to length was incremented instead. + - Added code to command line tool(s) which claims an interface. This code + is disabled by default, but may be necessary on newer Linux kernels. + - Added usbconfig.h option "USB_CFG_CHECK_DATA_TOGGLING". + - New header "usbportability.h" prepares ports to other development + environments. + - Long transfers (above 254 bytes) did not work when usbFunctionRead() was + used to supply the data. Fixed this bug. [Thanks to Alexander Neumann!] + - In hiddata.c (example code for sending/receiving data over HID), use + USB_RECIP_DEVICE instead of USB_RECIP_INTERFACE for control transfers so + that we need not claim the interface. + - in usbPoll() loop 20 times polling for RESET state instead of 10 times. + This accounts for the higher clock rates we now support. + - Added a module for 12.8 MHz RC oscillator with PLL in receiver loop. + - Added hook to SOF code so that oscillator can be tuned to USB frame clock. + - Added timeout to waitForJ loop. Helps preventing unexpected hangs. + - Added example code for oscillator tuning to libs-device (thanks to + Henrik Haftmann for the idea to this routine). + - Implemented option USB_CFG_SUPPRESS_INTR_CODE. + +* Release 2008-10-22 + + - Fixed libs-device/osctune.h: OSCCAL is memory address on ATMega88 and + similar, not offset of 0x20 needs to be added. + - Allow distribution under GPLv3 for those who have to link against other + code distributed under GPLv3. + +* Release 2008-11-26 + + - Removed libusb-win32 dependency for hid-data example in Makefile.windows. + It was never required and confused many people. + - Added extern uchar usbRxToken to usbdrv.h. + - Integrated a module with CRC checks at 18 MHz by Lukas Schrittwieser. + +* Release 2009-03-23 + + - Hid-mouse example used settings from hid-data example, fixed that. + - Renamed project to V-USB due to a trademark issue with Atmel(r). + - Changed CommercialLicense.txt and USBID-License.txt to make the + background of USB ID registration clearer. + +* Release 2009-04-15 + + - Changed CommercialLicense.txt to reflect the new range of PIDs from + Jason Kotzin. + - Removed USBID-License.txt in favor of USB-IDs-for-free.txt and + USB-ID-FAQ.txt + - Fixed a bug in the 12.8 MHz module: End Of Packet decection was made in + the center between bit 0 and 1 of each byte. This is where the data lines + are expected to change and the sampled data may therefore be nonsense. + We therefore check EOP ONLY if bits 0 AND 1 have both been read as 0 on D-. + - Fixed a bitstuffing problem in the 16 MHz module: If bit 6 was stuffed, + the unstuffing code in the receiver routine was 1 cycle too long. If + multiple bytes had the unstuffing in bit 6, the error summed up until the + receiver was out of sync. + - Included option for faster CRC routine. + Thanks to Slawomir Fras (BoskiDialer) for this code! + - Updated bits in Configuration Descriptor's bmAttributes according to + USB 1.1 (in particular bit 7, it is a must-be-set bit now). + +* Release 2009-08-22 + + - Moved first DBG1() after odDebugInit() in all examples. + - Use vector INT0_vect instead of SIG_INTERRUPT0 if defined. This makes + V-USB compatible with the new "p" suffix devices (e.g. ATMega328p). + - USB_CFG_CLOCK_KHZ setting is now required in usbconfig.h (no default any + more). + - New option USB_CFG_DRIVER_FLASH_PAGE allows boot loaders on devices with + more than 64 kB flash. + - Built-in configuration descriptor allows custom definition for second + endpoint now. + +* Release 2010-07-15 + + - Fixed bug in usbDriverSetup() which prevented descriptor sizes above 255 + bytes. + - Avoid a compiler warning for unused parameter in usbHandleResetHook() when + compiler option -Wextra is enabled. + - Fixed wrong hex value for some IDs in USB-IDs-for-free.txt. + - Keep a define for USBATTR_BUSPOWER, although the flag does not exist + in USB 1.1 any more. Set it to 0. This is for backward compatibility. + +* Release 2012-01-09 + + - Define a separate (defined) type for usbMsgPtr so that projects using a + tiny memory model can define it to an 8 bit type in usbconfig.h.

YOU CAN +ENTER INTO THIS AGREEMENT AND ACQUIRE THE RIGHTS OUTLINED BELOW BY PAYING +THE AMOUNT ACCORDING TO SECTION 4 ("PAYMENT") TO OBJECTIVE DEVELOPMENT. + + +1 DEFINITIONS + +1.1 "OBJECTIVE DEVELOPMENT" shall mean OBJECTIVE DEVELOPMENT Software GmbH, +Grosse Schiffgasse 1A/7, 1020 Wien, AUSTRIA. + +1.2 "You" shall mean the Licensee. + +1.3 "V-USB" shall mean all files included in the package distributed under +the name "vusb" by OBJECTIVE DEVELOPMENT (http://www.obdev.at/vusb/) +unless otherwise noted. This includes the firmware-only USB device +implementation for Atmel AVR microcontrollers, some simple device examples +and host side software examples and libraries. + + +2 LICENSE GRANTS + +2.1 Source Code. OBJECTIVE DEVELOPMENT shall furnish you with the source +code of V-USB. + +2.2 Distribution and Use. OBJECTIVE DEVELOPMENT grants you the +non-exclusive right to use, copy and distribute V-USB with your hardware +product(s), restricted by the limitations in section 3 below. + +2.3 Modifications. OBJECTIVE DEVELOPMENT grants you the right to modify +the source code and your copy of V-USB according to your needs. + +2.4 USB IDs. OBJECTIVE DEVELOPMENT furnishes you with one or two USB +Product ID(s), sent to you in e-mail. These Product IDs are reserved +exclusively for you. OBJECTIVE DEVELOPMENT has obtained USB Product ID +ranges under the Vendor ID 5824 from Wouter van Ooijen (Van Ooijen +Technische Informatica, www.voti.nl) and under the Vendor ID 8352 from +Jason Kotzin (now flirc.tv, Inc.). Both owners of the Vendor IDs have +obtained these IDs from the USB Implementers Forum, Inc. (www.usb.org). +OBJECTIVE DEVELOPMENT disclaims all liability which might arise from the +assignment of USB IDs. + +2.5 USB Certification. Although not part of this agreement, we want to make +it clear that you cannot become USB certified when you use V-USB or a USB +Product ID assigned by OBJECTIVE DEVELOPMENT. AVR microcontrollers don't +meet the electrical specifications required by the USB specification and +the USB Implementers Forum certifies only members who bought a Vendor ID of +their own. + + +3 LICENSE RESTRICTIONS + +3.1 Number of Units. Only one of the following three definitions is +applicable. Which one is determined by the amount you pay to OBJECTIVE +DEVELOPMENT, see section 4 ("Payment") below. + +Hobby License: You may use V-USB according to section 2 above in no more +than 5 hardware units. These units must not be sold for profit. + +Entry Level License: You may use V-USB according to section 2 above in no +more than 150 hardware units. + +Professional License: You may use V-USB according to section 2 above in +any number of hardware units, except for large scale production ("unlimited +fair use"). Quantities below 10,000 units are not considered large scale +production. If your reach quantities which are obviously large scale +production, you must pay a license fee of 0.10 EUR per unit for all units +above 10,000. + +3.2 Rental. You may not rent, lease, or lend V-USB or otherwise encumber +any copy of V-USB, or any of the rights granted herein. + +3.3 Transfer. You may not transfer your rights under this Agreement to +another party without OBJECTIVE DEVELOPMENT's prior written consent. If +such consent is obtained, you may permanently transfer this License to +another party. The recipient of such transfer must agree to all terms and +conditions of this Agreement. + +3.4 Reservation of Rights. OBJECTIVE DEVELOPMENT retains all rights not +expressly granted. + +3.5 Non-Exclusive Rights. Your license rights under this Agreement are +non-exclusive. + +3.6 Third Party Rights. This Agreement cannot grant you rights controlled +by third parties. In particular, you are not allowed to use the USB logo or +other trademarks owned by the USB Implementers Forum, Inc. without their +consent. Since such consent depends on USB certification, it should be +noted that V-USB will not pass certification because it does not +implement checksum verification and the microcontroller ports do not meet +the electrical specifications. + + +4 PAYMENT + +The payment amount depends on the variation of this agreement (according to +section 3.1) into which you want to enter. Concrete prices are listed on +OBJECTIVE DEVELOPMENT's web site, usually at +http://www.obdev.at/vusb/license.html.

By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program; if not, write to the Free Software + Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA + + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) year name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary.

These files should be linked to your project. + + +CPU CORE CLOCK FREQUENCY +======================== +We supply assembler modules for clock frequencies of 12 MHz, 12.8 MHz, 15 MHz, +16 MHz, 16.5 MHz 18 MHz and 20 MHz. Other clock rates are not supported. The +actual clock rate must be configured in usbconfig.h. + +12 MHz Clock +This is the traditional clock rate of V-USB because it's the lowest clock +rate where the timing constraints of the USB spec can be met. + +15 MHz Clock +Similar to 12 MHz, but some NOPs inserted. On the other hand, the higher clock +rate allows for some loops which make the resulting code size somewhat smaller +than the 12 MHz version. + +16 MHz Clock +This clock rate has been added for users of the Arduino board and other +ready-made boards which come with a fixed 16 MHz crystal. It's also an option +if you need the slightly higher clock rate for performance reasons. Since +16 MHz is not divisible by the USB low speed bit clock of 1.5 MHz, the code +is somewhat tricky and has to insert a leap cycle every third byte. + +12.8 MHz and 16.5 MHz Clock +The assembler modules for these clock rates differ from the other modules +because they have been built for an RC oscillator with only 1% precision. The +receiver code inserts leap cycles to compensate for clock deviations. 1% is +also the precision which can be achieved by calibrating the internal RC +oscillator of the AVR. Please note that only AVRs with internal 64 MHz PLL +oscillator can reach 16.5 MHz with the RC oscillator. This includes the very +popular ATTiny25, ATTiny45, ATTiny85 series as well as the ATTiny26. Almost +all AVRs can reach 12.8 MHz, although this is outside the specified range. + +See the EasyLogger example at http://www.obdev.at/vusb/easylogger.html for +code which calibrates the RC oscillator based on the USB frame clock. + +18 MHz Clock +This module is closer to the USB specification because it performs an on the +fly CRC check for incoming packets. Packets with invalid checksum are +discarded as required by the spec. If you also implement checks for data +PID toggling on application level (see option USB_CFG_CHECK_DATA_TOGGLING +in usbconfig.h for more info), this ensures data integrity. Due to the CRC +tables and alignment requirements, this code is bigger than modules for other +clock rates. To activate this module, you must define USB_CFG_CHECK_CRC to 1 +and USB_CFG_CLOCK_KHZ to 18000 in usbconfig.h. + +20 MHz Clock +This module is for people who won't do it with less than the maximum. Since +20 MHz is not divisible by the USB low speed bit clock of 1.5 MHz, the code +uses similar tricks as the 16 MHz module to insert leap cycles. + + +USB IDENTIFIERS +=============== +Every USB device needs a vendor- and a product-identifier (VID and PID). VIDs +are obtained from usb.org for a price of 1,500 USD. Once you have a VID, you +can assign PIDs at will. + +Since an entry level cost of 1,500 USD is too high for most small companies +and hobbyists, we provide some VID/PID pairs for free. See the file +USB-IDs-for-free.txt for details. + +Objective Development also has some license offerings which include product +IDs. See http://www.obdev.at/vusb/ for details. + + +DEVELOPMENT SYSTEM +================== +This driver has been developed and optimized for the GNU compiler version 3 +and 4. We recommend that you use the GNU compiler suite because it is freely +available. V-USB has also been ported to the IAR compiler and assembler. It +has been tested with IAR 4.10B/W32 and 4.12A/W32 on an ATmega8 with the +"small" and "tiny" memory model. Not every release is tested with IAR CC and +the driver may therefore fail to compile with IAR. Please note that gcc is +more efficient for usbdrv.c because this module has been deliberately +optimized for gcc. + +Gcc version 3 produces smaller code than version 4 due to new optimizing +capabilities which don't always improve things on 8 bit CPUs. The code size +generated by gcc 4 can be reduced with the compiler options +-fno-move-loop-invariants, -fno-tree-scev-cprop and +-fno-inline-small-functions in addition to -Os.

It also defines a +common set of requests which must be understood by all devices. And as part +of these common requests, the specification defines data structures, the +USB Descriptors, which are used to describe the properties of the device. + +From the perspective of an operating system, it is therefore possible to find +out basic properties of a device (such as e.g. the manufacturer and the name +of the device) without a device-specific driver. This is essential because +the operating system can choose a driver to load based on this information +(Plug-And-Play). + +Among the most important properties in the Device Descriptor are the USB +Vendor- and Product-ID. Both are 16 bit integers. The most simple form of +driver matching is based on these IDs. The driver announces the Vendor- and +Product-IDs of the devices it can handle and the operating system loads the +appropriate driver when the device is connected. + +It is obvious that this technique only works if the pair Vendor- plus +Product-ID is unique: Only devices which require the same driver can have the +same pair of IDs. + + +===================================================== +HOW DOES THE USB STANDARD ENSURE THAT IDs ARE UNIQUE? +===================================================== + +Since it is so important that USB IDs are unique, the USB Implementers Forum, +Inc. (usb.org) needs a way to enforce this legally. It is not forbidden by +law to build a device and assign it any random numbers as IDs. Usb.org +therefore needs an agreement to regulate the use of USB IDs. The agreement +binds only parties who agreed to it, of course. Everybody else is free to use +any numbers for their IDs. + +So how can usb.org ensure that every manufacturer of USB devices enters into +an agreement with them? They do it via trademark licensing. Usb.org has +registered the trademark "USB", all associated logos and related terms. If +you want to put an USB logo on your product or claim that it is USB +compliant, you must license these trademarks from usb.org. And this is where +you enter into an agreement. See the "USB-IF Trademark License Agreement and +Usage Guidelines for the USB-IF Logo" at +http://www.usb.org/developers/logo_license/. + +Licensing the USB trademarks requires that you buy a USB Vendor-ID from +usb.org (one-time fee of ca. 2,000 USD), that you become a member of usb.org +(yearly fee of ca. 4,000 USD) and that you meet all the technical +specifications from the USB spec. + +This means that most hobbyists and small companies will never be able to +become USB compliant, just because membership is so expensive. And you can't +be compliant with a driver based on V-USB anyway, because the AVR's port pins +don't meet the electrical specifications for USB. So, in principle, all +hobbyists and small companies are free to choose any random numbers for their +IDs. They have nothing to lose... + +There is one exception worth noting, though: If you use a sub-component which +implements USB, the vendor of the sub-components may guarantee USB +compliance. This might apply to some or all of FTDI's solutions. + + +======================================================================= +WHY SHOULD YOU OBTAIN USB IDs EVEN IF YOU DON'T LICENSE USB TRADEMARKS? +======================================================================= + +You have learned in the previous section that you are free to choose any +numbers for your IDs anyway. So why not do exactly this? There is still the +technical issue. If you choose IDs which are already in use by somebody else, +operating systems will load the wrong drivers and your device won't work. +Even if you choose IDs which are not currently in use, they may be in use in +the next version of the operating system or even after an automatic update. + +So what you need is a pair of Vendor- and Product-IDs for which you have the +guarantee that no USB compliant product uses them. This implies that no +operating system will ever ship with drivers responsible for these IDs. + + +============================================== +HOW DOES OBJECTIVE DEVELOPMENT HANDLE USB IDs? +============================================== + +Objective Development gives away pairs of USB-IDs with their V-USB licenses. +In order to ensure that these IDs are unique, Objective Development has an +agreement with the company/person who has bought the USB Vendor-ID from +usb.org. This agreement ensures that a range of USB Product-IDs is reserved +for assignment by Objective Development and that the owner of the Vendor-ID +won't give it to anybody else. + +This means that you have to trust three parties to ensure uniqueness of +your IDs: + + - Objective Development, that they don't give the same PID to more than + one person. + - The owner of the Vendor-ID that they don't assign PIDs from the range + assigned to Objective Development to anybody else. + - Usb.org that they don't assign the same Vendor-ID a second time. + + +================================== +WHO IS THE OWNER OF THE VENDOR-ID? +================================== + +Objective Development has obtained ranges of USB Product-IDs under two +Vendor-IDs: Under Vendor-ID 5824 from Wouter van Ooijen (Van Ooijen +Technische Informatica, www.voti.nl) and under Vendor-ID 8352 from Jason +Kotzin (now flirc.tv, Inc.). Both VID owners have received their Vendor-ID +directly from usb.org. + + +========================================================================= +CAN I USE USB-IDs FROM OBJECTIVE DEVELOPMENT WITH OTHER DRIVERS/HARDWARE? +========================================================================= + +The short answer is: Yes. All you get is a guarantee that the IDs are never +assigned to anybody else. What more do you need? + + +============================ +WHAT ABOUT SHARED ID PAIRS? +============================ + +Objective Development has reserved some PID/VID pairs for shared use. You +have no guarantee of uniqueness for them, except that no USB compliant device +uses them. In order to avoid technical problems, we must ensure that all +devices with the same pair of IDs use the same driver on kernel level. For +details, see the file USB-IDs-for-free.txt. + + +====================================================== +I HAVE HEARD THAT SUB-LICENSING OF USB-IDs IS ILLEGAL? +====================================================== + +A 16 bit integer number cannot be protected by copyright laws. It is not +sufficiently complex. And since none of the parties involved entered into the +USB-IF Trademark License Agreement, we are not bound by this agreement. So +there is no reason why it should be illegal to sub-license USB-IDs. + + +============================================= +WHO IS LIABLE IF THERE ARE INCOMPATIBILITIES? +============================================= + +Objective Development disclaims all liabilities which might arise from the +assignment of IDs. If you guarantee product features to your customers +without proper disclaimer, YOU are liable for that. diff --git a/usbdrv/USB-IDs-for-free.txt b/usbdrv/USB-IDs-for-free.txt new file mode 100644 index 0000000..8f44427 --- /dev/null +++ b/usbdrv/USB-IDs-for-free.txt @@ -0,0 +1,168 @@ +Version 2009-08-22 + +=========================== +FREE USB-IDs FOR SHARED USE +=========================== + +Objective Development has reserved a set of USB Product-IDs for use according +to the guidelines outlined below.

We recommend that D+ +triggers the interrupt (best achieved by using INT0 for D+), but it is also +possible to trigger the interrupt from D-. If D- is used, interrupts are also +triggered by SOF packets. D- requires a pull-up of 1.5k to +3.5V (and the +device must be powered at 3.5V) to identify as low-speed USB device. A +pull-down or pull-up of 1M SHOULD be connected from D+ to +3.5V to prevent +interference when no USB master is connected. If you use Zener diodes to limit +the voltage on D+ and D-, you MUST use a pull-down resistor, not a pull-up. +We use D+ as interrupt source and not D- because it does not trigger on +keep-alive and RESET states. If you want to count keep-alive events with +USB_COUNT_SOF, you MUST use D- as an interrupt source. + +As a compile time option, the 1.5k pull-up resistor on D- can be made +switchable to allow the device to disconnect at will. See the definition of +usbDeviceConnect() and usbDeviceDisconnect() further down in this file. + +Please adapt the values in usbconfig.h according to your hardware! + +The device MUST be clocked at exactly 12 MHz, 15 MHz, 16 MHz or 20 MHz +or at 12.8 MHz resp. 16.5 MHz +/- 1%. See usbconfig-prototype.h for details. + + +Limitations: +============ +Robustness with respect to communication errors: +The driver assumes error-free communication. It DOES check for errors in +the PID, but does NOT check bit stuffing errors, SE0 in middle of a byte, +token CRC (5 bit) and data CRC (16 bit). CRC checks can not be performed due +to timing constraints: We must start sending a reply within 7 bit times. +Bit stuffing and misplaced SE0 would have to be checked in real-time, but CPU +performance does not permit that. The driver does not check Data0/Data1 +toggling, but application software can implement the check. + +Input characteristics: +Since no differential receiver circuit is used, electrical interference +robustness may suffer. The driver samples only one of the data lines with +an ordinary I/O pin's input characteristics. However, since this is only a +low speed USB implementation and the specification allows for 8 times the +bit rate over the same hardware, we should be on the safe side. Even the spec +requires detection of asymmetric states at high bit rate for SE0 detection. + +Number of endpoints: +The driver supports the following endpoints: + +- Endpoint 0, the default control endpoint. +- Any number of interrupt- or bulk-out endpoints. The data is sent to + usbFunctionWriteOut() and USB_CFG_IMPLEMENT_FN_WRITEOUT must be defined + to 1 to activate this feature. The endpoint number can be found in the + global variable 'usbRxToken'. +- One default interrupt- or bulk-in endpoint. This endpoint is used for + interrupt- or bulk-in transfers which are not handled by any other endpoint. + You must define USB_CFG_HAVE_INTRIN_ENDPOINT in order to activate this + feature and call usbSetInterrupt() to send interrupt/bulk data. +- One additional interrupt- or bulk-in endpoint. This was endpoint 3 in + previous versions of this driver but can now be configured to any endpoint + number. You must define USB_CFG_HAVE_INTRIN_ENDPOINT3 in order to activate + this feature and call usbSetInterrupt3() to send interrupt/bulk data. The + endpoint number can be set with USB_CFG_EP3_NUMBER. + +Please note that the USB standard forbids bulk endpoints for low speed devices! +Most operating systems allow them anyway, but the AVR will spend 90% of the CPU +time in the USB interrupt polling for bulk data. + +Maximum data payload: +Data payload of control in and out transfers may be up to 254 bytes. In order +to accept payload data of out transfers, you need to implement +'usbFunctionWrite()'. + +USB Suspend Mode supply current: +The USB standard limits power consumption to 500uA when the bus is in suspend +mode. This is not a problem for self-powered devices since they don't need +bus power anyway. Bus-powered devices can achieve this only by putting the +CPU in sleep mode. The driver does not implement suspend handling by itself. +However, the application may implement activity monitoring and wakeup from +sleep. The host sends regular SE0 states on the bus to keep it active. These +SE0 states can be detected by using D- as the interrupt source. Define +USB_COUNT_SOF to 1 and use the global variable usbSofCount to check for bus +activity. + +Operation without an USB master: +The driver behaves neutral without connection to an USB master if D- reads +as 1. To avoid spurious interrupts, we recommend a high impedance (e.g. 1M) +pull-down or pull-up resistor on D+ (interrupt). If Zener diodes are used, +use a pull-down. If D- becomes statically 0, the driver may block in the +interrupt routine. + +Interrupt latency: +The application must ensure that the USB interrupt is not disabled for more +than 25 cycles (this is for 12 MHz, faster clocks allow longer latency). +This implies that all interrupt routines must either have the "ISR_NOBLOCK" +attribute set (see "avr/interrupt.h") or be written in assembler with "sei" +as the first instruction. + +Maximum interrupt duration / CPU cycle consumption: +The driver handles all USB communication during the interrupt service +routine. The routine will not return before an entire USB message is received +and the reply is sent. This may be up to ca. 1200 cycles @ 12 MHz (= 100us) if +the host conforms to the standard. The driver will consume CPU cycles for all +USB messages, even if they address another (low-speed) device on the same bus. + +*/ + + +#ifdef __cplusplus +// This header should be included as C-header from C++ code.

So in fact the highest order +; bit seen from the polynomial devision point of view is the lsb of ZL. (If this sounds strange to you i +; propose a research on CRC :-) ) +; Each data byte received is xored to ZL, the lower crc byte. This byte now builds the crc +; table index. Next the new high byte is loaded from the table and stored in x4 until we have space in x3 +; (its destination). +; Afterwards the lower table is loaded from the table and stored in ZL (the old index is overwritten as +; we don't need it anymore. In fact this is a right shift by 8 bits.) Now the old crc high value is xored +; to ZL, this is the second shift of the old crc value. Now x4 (the temp reg) is moved to x3 and the crc +; calculation is done. +; Prior to the first byte the two CRC register have to be initialized to 0xFFFF (as defined in usb spec) +; however the crc engine also runs during the receipt of the first byte, therefore x3 and zl are initialized +; to a magic number which results in a crc value of 0xFFFF after the first complete byte. +; +; This algorithm is split into the extra cycles of the different bits: +; bit7: XOR the received byte to ZL +; bit5: load the new high byte to x4 +; bit6: load the lower xor byte from the table, xor zl and x3, store result in zl (=the new crc low value) +; move x4 (the new high byte) to x3, the crc value is ready +; + + +macro POP_STANDARD ; 18 cycles + pop ZH + pop ZL + pop cnt + pop x5 + pop x3 + pop x2 + pop x1 + pop shift + pop x4 + endm +macro POP_RETI ; 7 cycles + pop YH + pop YL + out SREG, YL + pop YL + endm + +macro CRC_CLEANUP_AND_CHECK + ; the last byte has already been xored with the lower crc byte, we have to do the table lookup and xor + ; x3 is the higher crc byte, zl the lower one + ldi ZH, hi8(usbCrcTableHigh);[+1] get the new high byte from the table + lpm x2, Z ;[+2][+3][+4] + ldi ZH, hi8(usbCrcTableLow);[+5] get the new low xor byte from the table + lpm ZL, Z ;[+6][+7][+8] + eor ZL, x3 ;[+7] xor the old high byte with the value from the table, x2:ZL now holds the crc value + cpi ZL, 0x01 ;[+8] if the crc is ok we have a fixed remainder value of 0xb001 in x2:ZL (see usb spec) + brne ignorePacket ;[+9] detected a crc fault -> paket is ignored and retransmitted by the host + cpi x2, 0xb0 ;[+10] + brne ignorePacket ;[+11] detected a crc fault -> paket is ignored and retransmitted by the host + endm + + +USB_INTR_VECTOR: +;order of registers pushed: YL, SREG, YH, [sofError], x4, shift, x1, x2, x3, x5, cnt, ZL, ZH + push YL ;[-28] push only what is necessary to sync with edge ASAP + in YL, SREG ;[-26] + push YL ;[-25] + push YH ;[-23] +;---------------------------------------------------------------------------- +; Synchronize with sync pattern: +;---------------------------------------------------------------------------- +;sync byte (D-) pattern LSb to MSb: 01010100 [1 = idle = J, 0 = K] +;sync up with J to K edge during sync pattern -- use fastest possible loops +;The first part waits at most 1 bit long since we must be in sync pattern. +;YL is guarenteed to be < 0x80 because I flag is clear.
