1 GNU GENERAL PUBLIC LICENSE
2 Version 2, June 1991
3
4 Copyright (C) 1989, 1991 Free Software Foundation, Inc.
5 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
6 Everyone is permitted to copy and distribute verbatim copies
7 of this license document, but changing it is not allowed.
8
9 Preamble
10
11 The licenses for most software are designed to take away your
12freedom to share and change it. By contrast, the GNU General Public
13License is intended to guarantee your freedom to share and change free
14software--to make sure the software is free for all its users. This
15General Public License applies to most of the Free Software
16Foundation's software and to any other program whose authors commit to
17using it. (Some other Free Software Foundation software is covered by
18the GNU Library General Public License instead.) You can apply it to
19your programs, too.
20
21 When we speak of free software, we are referring to freedom, not
22price. Our General Public Licenses are designed to make sure that you
23have the freedom to distribute copies of free software (and charge for
24this service if you wish), that you receive source code or can get it
25if you want it, that you can change the software or use pieces of it
26in new free programs; and that you know you can do these things.
27
28 To protect your rights, we need to make restrictions that forbid
29anyone to deny you these rights or to ask you to surrender the rights.
30These restrictions translate to certain responsibilities for you if you
31distribute copies of the software, or if you modify it.
32
33 For example, if you distribute copies of such a program, whether
34gratis or for a fee, you must give the recipients all the rights that
35you have. You must make sure that they, too, receive or can get the
36source code. And you must show them these terms so they know their
37rights.
38
39 We protect your rights with two steps: (1) copyright the software, and
40(2) offer you this license which gives you legal permission to copy,
41distribute and/or modify the software.
42
43 Also, for each author's protection and ours, we want to make certain
44that everyone understands that there is no warranty for this free
45software. If the software is modified by someone else and passed on, we
46want its recipients to know that what they have is not the original, so
47that any problems introduced by others will not reflect on the original
48authors' reputations.
49
50 Finally, any free program is threatened constantly by software
51patents. We wish to avoid the danger that redistributors of a free
52program will individually obtain patent licenses, in effect making the
53program proprietary. To prevent this, we have made it clear that any
54patent must be licensed for everyone's free use or not licensed at all.
55
56 The precise terms and conditions for copying, distribution and
57modification follow.
58
59 GNU GENERAL PUBLIC LICENSE
60 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
61
62 0. This License applies to any program or other work which contains
63a notice placed by the copyright holder saying it may be distributed
64under the terms of this General Public License. The "Program", below,
65refers to any such program or work, and a "work based on the Program"
66means either the Program or any derivative work under copyright law:
67that is to say, a work containing the Program or a portion of it,
68either verbatim or with modifications and/or translated into another
69language. (Hereinafter, translation is included without limitation in
70the term "modification".) Each licensee is addressed as "you".
71
72Activities other than copying, distribution and modification are not
73covered by this License; they are outside its scope. The act of
74running the Program is not restricted, and the output from the Program
75is covered only if its contents constitute a work based on the
76Program (independent of having been made by running the Program).
77Whether that is true depends on what the Program does.
78
79 1. You may copy and distribute verbatim copies of the Program's
80source code as you receive it, in any medium, provided that you
81conspicuously and appropriately publish on each copy an appropriate
82copyright notice and disclaimer of warranty; keep intact all the
83notices that refer to this License and to the absence of any warranty;
84and give any other recipients of the Program a copy of this License
85along with the Program.
86
87You may charge a fee for the physical act of transferring a copy, and
88you may at your option offer warranty protection in exchange for a fee.
89
90 2. You may modify your copy or copies of the Program or any portion
91of it, thus forming a work based on the Program, and copy and
92distribute such modifications or work under the terms of Section 1
93above, provided that you also meet all of these conditions:
94
95 a) You must cause the modified files to carry prominent notices
96 stating that you changed the files and the date of any change.
97
98 b) You must cause any work that you distribute or publish, that in
99 whole or in part contains or is derived from the Program or any
100 part thereof, to be licensed as a whole at no charge to all third
101 parties under the terms of this License.
102
103 c) If the modified program normally reads commands interactively
104 when run, you must cause it, when started running for such
105 interactive use in the most ordinary way, to print or display an
106 announcement including an appropriate copyright notice and a
107 notice that there is no warranty (or else, saying that you provide
108 a warranty) and that users may redistribute the program under
109 these conditions, and telling the user how to view a copy of this
110 License. (Exception: if the Program itself is interactive but
111 does not normally print such an announcement, your work based on
112 the Program is not required to print an announcement.)
113
114These requirements apply to the modified work as a whole. If
115identifiable sections of that work are not derived from the Program,
116and can be reasonably considered independent and separate works in
117themselves, then this License, and its terms, do not apply to those
118sections when you distribute them as separate works. But when you
119distribute the same sections as part of a whole which is a work based
120on the Program, the distribution of the whole must be on the terms of
121this License, whose permissions for other licensees extend to the
122entire whole, and thus to each and every part regardless of who wrote it.
123
124Thus, it is not the intent of this section to claim rights or contest
125your rights to work written entirely by you; rather, the intent is to
126exercise the right to control the distribution of derivative or
127collective works based on the Program.
128
129In addition, mere aggregation of another work not based on the Program
130with the Program (or with a work based on the Program) on a volume of
131a storage or distribution medium does not bring the other work under
132the scope of this License.
133
134 3. You may copy and distribute the Program (or a work based on it,
135under Section 2) in object code or executable form under the terms of
136Sections 1 and 2 above provided that you also do one of the following:
137
138 a) Accompany it with the complete corresponding machine-readable
139 source code, which must be distributed under the terms of Sections
140 1 and 2 above on a medium customarily used for software interchange; or,
141
142 b) Accompany it with a written offer, valid for at least three
143 years, to give any third party, for a charge no more than your
144 cost of physically performing source distribution, a complete
145 machine-readable copy of the corresponding source code, to be
146 distributed under the terms of Sections 1 and 2 above on a medium
147 customarily used for software interchange; or,
148
149 c) Accompany it with the information you received as to the offer
150 to distribute corresponding source code. (This alternative is
151 allowed only for noncommercial distribution and only if you
152 received the program in object code or executable form with such
153 an offer, in accord with Subsection b above.)
154
155The source code for a work means the preferred form of the work for
156making modifications to it. For an executable work, complete source
157code means all the source code for all modules it contains, plus any
158associated interface definition files, plus the scripts used to
159control compilation and installation of the executable. However, as a
160special exception, the source code distributed need not include
161anything that is normally distributed (in either source or binary
162form) with the major components (compiler, kernel, and so on) of the
163operating system on which the executable runs, unless that component
164itself accompanies the executable.
165
166If distribution of executable or object code is made by offering
167access to copy from a designated place, then offering equivalent
168access to copy the source code from the same place counts as
169distribution of the source code, even though third parties are not
170compelled to copy the source along with the object code.
171
172 4. You may not copy, modify, sublicense, or distribute the Program
173except as expressly provided under this License. Any attempt
174otherwise to copy, modify, sublicense or distribute the Program is
175void, and will automatically terminate your rights under this License.
176However, parties who have received copies, or rights, from you under
177this License will not have their licenses terminated so long as such
178parties remain in full compliance.
179
180 5. You are not required to accept this License, since you have not
181signed it. However, nothing else grants you permission to modify or
182distribute the Program or its derivative works. These actions are
183prohibited by law if you do not accept this License. Therefore, by
184modifying or distributing the Program (or any work based on the
185Program), you indicate your acceptance of this License to do so, and
186all its terms and conditions for copying, distributing or modifying
187the Program or works based on it.
188
189 6. Each time you redistribute the Program (or any work based on the
190Program), the recipient automatically receives a license from the
191original licensor to copy, distribute or modify the Program subject to
192these terms and conditions. You may not impose any further
193restrictions on the recipients' exercise of the rights granted herein.
194You are not responsible for enforcing compliance by third parties to
195this License.
196
197 7. If, as a consequence of a court judgment or allegation of patent
198infringement or for any other reason (not limited to patent issues),
199conditions are imposed on you (whether by court order, agreement or
200otherwise) that contradict the conditions of this License, they do not
201excuse you from the conditions of this License. If you cannot
202distribute so as to satisfy simultaneously your obligations under this
203License and any other pertinent obligations, then as a consequence you
204may not distribute the Program at all. For example, if a patent
205license would not permit royalty-free redistribution of the Program by
206all those who receive copies directly or indirectly through you, then
207the only way you could satisfy both it and this License would be to
208refrain entirely from distribution of the Program.
209
210If any portion of this section is held invalid or unenforceable under
211any particular circumstance, the balance of the section is intended to
212apply and the section as a whole is intended to apply in other
213circumstances.
214
215It is not the purpose of this section to induce you to infringe any
216patents or other property right claims or to contest validity of any
217such claims; this section has the sole purpose of protecting the
218integrity of the free software distribution system, which is
219implemented by public license practices. Many people have made
220generous contributions to the wide range of software distributed
221through that system in reliance on consistent application of that
222system; it is up to the author/donor to decide if he or she is willing
223to distribute software through any other system and a licensee cannot
224impose that choice.
225
226This section is intended to make thoroughly clear what is believed to
227be a consequence of the rest of this License.
228
229 8. If the distribution and/or use of the Program is restricted in
230certain countries either by patents or by copyrighted interfaces, the
231original copyright holder who places the Program under this License
232may add an explicit geographical distribution limitation excluding
233those countries, so that distribution is permitted only in or among
234countries not thus excluded. In such case, this License incorporates
235the limitation as if written in the body of this License.
236
237 9. The Free Software Foundation may publish revised and/or new versions
238of the General Public License from time to time. Such new versions will
239be similar in spirit to the present version, but may differ in detail to
240address new problems or concerns.
241
242Each version is given a distinguishing version number. If the Program
243specifies a version number of this License which applies to it and "any
244later version", you have the option of following the terms and conditions
245either of that version or of any later version published by the Free
246Software Foundation. If the Program does not specify a version number of
247this License, you may choose any version ever published by the Free Software
248Foundation.
249
250 10. If you wish to incorporate parts of the Program into other free
251programs whose distribution conditions are different, write to the author
252to ask for permission. For software which is copyrighted by the Free
253Software Foundation, write to the Free Software Foundation; we sometimes
254make exceptions for this. Our decision will be guided by the two goals
255of preserving the free status of all derivatives of our free software and
256of promoting the sharing and reuse of software generally.
257
258 NO WARRANTY
259
260 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
261FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
262OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
263PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
264OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
265MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
266TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
267PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
268REPAIR OR CORRECTION.
269
270 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
271WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
272REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
273INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
274OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED

282 How to Apply These Terms to Your New Programs
283
284 If you develop a new program, and you want it to be of the greatest
285possible use to the public, the best way to achieve this is to make it
286free software which everyone can redistribute and change under these terms.
287
288 To do so, attach the following notices to the program. It is safest
289to attach them to the start of each source file to most effectively
290convey the exclusion of warranty; and each file should have at least
291the "copyright" line and a pointer to where the full notice is found.
292
293 <one line to give the program's name and a brief idea of what it does.>
294 Copyright (C) <year> <name of author>
295
296 This program is free software; you can redistribute it and/or modify
297 it under the terms of the GNU General Public License as published by
298 the Free Software Foundation; either version 2 of the License, or
299 (at your option) any later version.
300
301 This program is distributed in the hope that it will be useful,
302 but WITHOUT ANY WARRANTY; without even the implied warranty of
303 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
304 GNU General Public License for more details.
305
306 You should have received a copy of the GNU General Public License
307 along with this program; if not, write to the Free Software
308 Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
309
310
311Also add information on how to contact you by electronic and paper mail.
312
313If the program is interactive, make it output a short notice like this
314when it starts in an interactive mode:
315
316 Gnomovision version 69, Copyright (C) year name of author
317 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
318 This is free software, and you are welcome to redistribute it
319 under certain conditions; type `show c' for details.
320
321The hypothetical commands `show w' and `show c' should show the appropriate
322parts of the General Public License. Of course, the commands you use may
323be called something other than `show w' and `show c'; they could even be
324mouse-clicks or menu items--whatever suits your program.
325
326You should also get your employer (if you work as a programmer) or your
327school, if any, to sign a "copyright disclaimer" for the program, if
328necessary. Here is a sample; alter the names:
329
330 Yoyodyne, Inc., hereby disclaims all copyright interest in the program
331 `Gnomovision' (which makes passes at compilers) written by James Hacker.

335
336This General Public License does not permit incorporating your program into
337proprietary programs. If your program is a subroutine library, you may
338consider it more useful to permit linking proprietary applications with the
339library. If this is what you want to do, use the GNU Library General
340Public License instead of this License.

1Installation Instructions

6
7This file is free documentation; the Free Software Foundation gives
8unlimited permission to copy, distribute and modify it.
9
10Basic Installation
11==================
12
13Briefly, the shell commands `./configure; make; make install' should
14configure, build, and install this package. The following
15more-detailed instructions are generic; see the `README' file for
16instructions specific to this package.
17
18 The `configure' shell script attempts to guess correct values for
19various system-dependent variables used during compilation. It uses
20those values to create a `Makefile' in each directory of the package.
21It may also create one or more `.h' files containing system-dependent
22definitions. Finally, it creates a shell script `config.status' that
23you can run in the future to recreate the current configuration, and a
24file `config.log' containing compiler output (useful mainly for
25debugging `configure').
26
27 It can also use an optional file (typically called `config.cache'
28and enabled with `--cache-file=config.cache' or simply `-C') that saves
29the results of its tests to speed up reconfiguring. Caching is
30disabled by default to prevent problems with accidental use of stale
31cache files.
32
33 If you need to do unusual things to compile the package, please try
34to figure out how `configure' could check whether to do them, and mail
35diffs or instructions to the address given in the `README' so they can
36be considered for the next release. If you are using the cache, and at
37some point `config.cache' contains results you don't want to keep, you
38may remove or edit it.
39
40 The file `configure.ac' (or `configure.in') is used to create
41`configure' by a program called `autoconf'. You need `configure.ac' if
42you want to change it or regenerate `configure' using a newer version
43of `autoconf'.
44
45The simplest way to compile this package is:
46
47 1. `cd' to the directory containing the package's source code and type
48 `./configure' to configure the package for your system.
49
50 Running `configure' might take a while. While running, it prints
51 some messages telling which features it is checking for.
52
53 2. Type `make' to compile the package.
54
55 3. Optionally, type `make check' to run any self-tests that come with
56 the package.
57
58 4. Type `make install' to install the programs and any data files and
59 documentation.
60
61 5. You can remove the program binaries and object files from the
62 source code directory by typing `make clean'. To also remove the
63 files that `configure' created (so you can compile the package for
64 a different kind of computer), type `make distclean'. There is
65 also a `make maintainer-clean' target, but that is intended mainly
66 for the package's developers. If you use it, you may have to get
67 all sorts of other programs in order to regenerate files that came
68 with the distribution.
69
70 6. Often, you can also type `make uninstall' to remove the installed
71 files again.
72
73Compilers and Options
74=====================
75
76Some systems require unusual options for compilation or linking that the
77`configure' script does not know about. Run `./configure --help' for
78details on some of the pertinent environment variables.
79
80 You can give `configure' initial values for configuration parameters
81by setting variables in the command line or in the environment. Here
82is an example:
83
84 ./configure CC=c99 CFLAGS=-g LIBS=-lposix
85
86 *Note Defining Variables::, for more details.
87
88Compiling For Multiple Architectures
89====================================
90
91You can compile the package for more than one kind of computer at the
92same time, by placing the object files for each architecture in their
93own directory. To do this, you can use GNU `make'. `cd' to the
94directory where you want the object files and executables to go and run
95the `configure' script. `configure' automatically checks for the
96source code in the directory that `configure' is in and in `..'.
97
98 With a non-GNU `make', it is safer to compile the package for one
99architecture at a time in the source code directory. After you have
100installed the package for one architecture, use `make distclean' before
101reconfiguring for another architecture.
102
103Installation Names
104==================
105
106By default, `make install' installs the package's commands under
107`/usr/local/bin', include files under `/usr/local/include', etc. You
108can specify an installation prefix other than `/usr/local' by giving
109`configure' the option `--prefix=PREFIX'.
110
111 You can specify separate installation prefixes for
112architecture-specific files and architecture-independent files. If you
113pass the option `--exec-prefix=PREFIX' to `configure', the package uses
114PREFIX as the prefix for installing programs and libraries.
115Documentation and other data files still use the regular prefix.
116
117 In addition, if you use an unusual directory layout you can give
118options like `--bindir=DIR' to specify different values for particular
119kinds of files. Run `configure --help' for a list of the directories
120you can set and what kinds of files go in them.
121
122 If the package supports it, you can cause programs to be installed
123with an extra prefix or suffix on their names by giving `configure' the
124option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
125
126Optional Features
127=================
128
129Some packages pay attention to `--enable-FEATURE' options to
130`configure', where FEATURE indicates an optional part of the package.
131They may also pay attention to `--with-PACKAGE' options, where PACKAGE
132is something like `gnu-as' or `x' (for the X Window System). The
133`README' should mention any `--enable-' and `--with-' options that the
134package recognizes.
135
136 For packages that use the X Window System, `configure' can usually
137find the X include and library files automatically, but if it doesn't,
138you can use the `configure' options `--x-includes=DIR' and
139`--x-libraries=DIR' to specify their locations.
140
141Specifying the System Type
142==========================
143
144There may be some features `configure' cannot figure out automatically,
145but needs to determine by the type of machine the package will run on.
146Usually, assuming the package is built to be run on the _same_
147architectures, `configure' can figure that out, but if it prints a
148message saying it cannot guess the machine type, give it the
149`--build=TYPE' option. TYPE can either be a short name for the system
150type, such as `sun4', or a canonical name which has the form:
151
152 CPU-COMPANY-SYSTEM
153
154where SYSTEM can have one of these forms:
155
156 OS KERNEL-OS
157
158 See the file `config.sub' for the possible values of each field. If
159`config.sub' isn't included in this package, then this package doesn't
160need to know the machine type.
161
162 If you are _building_ compiler tools for cross-compiling, you should
163use the option `--target=TYPE' to select the type of system they will
164produce code for.
165
166 If you want to _use_ a cross compiler, that generates code for a
167platform different from the build platform, you should specify the
168"host" platform (i.e., that on which the generated programs will
169eventually be run) with `--host=TYPE'.
170
171Sharing Defaults
172================
173
174If you want to set default values for `configure' scripts to share, you
175can create a site shell script called `config.site' that gives default
176values for variables like `CC', `cache_file', and `prefix'.
177`configure' looks for `PREFIX/share/config.site' if it exists, then
178`PREFIX/etc/config.site' if it exists. Or, you can set the
179`CONFIG_SITE' environment variable to the location of the site script.
180A warning: not all `configure' scripts look for a site script.
181
182Defining Variables
183==================
184
185Variables not defined in a site shell script can be set in the
186environment passed to `configure'. However, some packages may run
187configure again during the build, and the customized values of these
188variables may be lost. In order to avoid this problem, you should set
189them in the `configure' command line, using `VAR=value'. For example:
190
191 ./configure CC=/usr/local2/bin/gcc
192
193causes the specified `gcc' to be used as the C compiler (unless it is
194overridden in the site shell script).
195
196Unfortunately, this technique does not work for `CONFIG_SHELL' due to
197an Autoconf bug. Until the bug is fixed you can use this workaround:
198
199 CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
200
201`configure' Invocation
202======================
203
204`configure' recognizes the following options to control how it operates.
205
206`--help'
207`-h'
208 Print a summary of the options to `configure', and exit.
209
210`--version'
211`-V'
212 Print the version of Autoconf used to generate the `configure'
213 script, and exit.
214
215`--cache-file=FILE'
216 Enable the cache: use and save the results of the tests in FILE,
217 traditionally `config.cache'. FILE defaults to `/dev/null' to
218 disable caching.
219
220`--config-cache'
221`-C'
222 Alias for `--cache-file=config.cache'.
223
224`--quiet'
225`--silent'
226`-q'
227 Do not print messages saying which checks are being made. To
228 suppress all normal output, redirect it to `/dev/null' (any error
229 messages will still be shown).
230
231`--srcdir=DIR'
232 Look for the package's source code in directory DIR. Usually
233 `configure' can determine that directory automatically.
234
235`configure' also accepts some other, not widely useful, options. Run
236`configure --help' for more details.

190[Checklist]
191 - See 'Debug Tips' on the project wiki.
192 - http://usbip.wiki.sourceforge.net/how-to-debug-usbip
193 - usbip-host.ko must be bound to the target device.
194 - See /proc/bus/usb/devices and find "Driver=..." lines of the device.
195 - Shutdown firewall.
196 - usbip now uses TCP port 3240.
197 - Disable SELinux.
198 - Check the kernel and daemon messages.

4.SH SYNOPSIS
5.B usbipd
6[\fIoptions\fR]
7
8.SH DESCRIPTION
9.B usbipd
10provides USB/IP clients access to exported USB devices.
11
12Devices have to explicitly be exported using
13.B usbip bind

66.PP
67
68.SH LIMITATIONS
69
70.B usbipd
71offers no authentication or authorization for USB/IP. Any
72USB/IP client can connect and use exported devices.
73
74.SH EXAMPLES
75
76 server:# modprobe usbip
77
78 server:# usbipd -D
79 - Start usbip daemon.
80
81 server:# usbip list --local
82 - List driver assignments for usb devices.
83
84 server:# usbip bind --busid=1-2
85 - Bind usbip-host.ko to the device of busid 1-2.
86 - A usb device 1-2 is now exportable to other hosts!
87 - Use 'usbip unbind --busid=1-2' when you want to shutdown exporting and use the device locally.
