3
42012-09-26: v1.0.14
5* Reverts the previous API change with regards to bMaxPower.
6 If this doesn't matter to you, you are encouraged to keep using v1.0.13,
7 as it will use the same attribute as v2.0, to be released soon.
8* Note that LIBUSBX_API_VERSION is *decreased* to 0x010000FF and the previous
9 guidelines with regards to concurent use of MaxPower/bMaxPower still apply.
10
112012-09-20: v1.0.13
12* [MAJOR] Fix a typo in the API with struct libusb_config_descriptor where
13 MaxPower was used instead of bMaxPower, as defined in the specs. If your
14 application was accessing the MaxPower attribute, and you need to maintain
15 compatibility with libusb or older versions, see APPENDIX A below.
16* Fix broken support for the 0.1 -> 1.0 libusb-compat layer
17* Fix unwanted cancellation of pending timeouts as well as major timeout related bugs
18* Fix handling of HID and composite devices on Windows
19* Introduce LIBUSBX_API_VERSION macro
20* Add Cypress FX/FX2 firmware upload sample, based on fxload from
21 http://linux-hotplug.sourceforge.net
22* Add libusb0 (libusb-win32) and libusbK driver support on Windows. Note that while
23 the drivers allow it, isochronous transfers are not supported yet in libusbx. Also
24 not supported yet is the use of libusb-win32 filter drivers on composite interfaces
25* Add support for the new get_capabilities ioctl on Linux and avoid unnecessary
26 splitting of bulk transfers
27* Improve support for newer Intel and Renesas USB 3.0 controllers on Windows
28* Harmonize the device number for root hubs across platforms
29* Other bug fixes and improvements
30
312012-06-15: v1.0.12
32* Fix a potential major regression with pthread on Linux
33* Fix missing thread ID from debug log output on cygwin
34* Fix possible crash when using longjmp and MinGW's gcc 4.6
35* Add topology calls: libusb_get_port_number(), libusb_get_parent() & libusb_get_port_path()
36* Add toggleable debug, using libusb_set_debug() or the LIBUSB_DEBUG environment variable
37* Define log levels in libusb.h and set timestamp origin to first libusb_init() call
38* All logging is now sent to to stderr (info was sent to stdout previously)
39* Update log messages severity and avoid polluting log output on OS-X
40* Add HID driver support on Windows
41* Enable interchangeability of MSVC and MinGW DLLs
42* Additional bug fixes and improvements
43
442012-05-08: v1.0.11
45* Revert removal of critical Windows event handling that was introduced in 1.0.10
46* Fix a possible deadlock in Windows when submitting transfers
47* Add timestamped logging
48* Add NetBSD support (experimental) and BSD libusb_get_device_speed() data
49* Add bootstrap.sh alongside autogen.sh (bootstrap.sh doesn't invoke configure)
50* Search for device nodes in /dev for Android support
51* Other bug fixes
52
532012-04-17: v1.0.10
54* Public release
55* Add libusb_get_version
56* Add Visual Studio 2010 project files
57* Some Windows code cleanup
58* Fix xusb sample warnings
59
602012-04-02: v1.0.9
61* First libusbx release
62* Add libusb_get_device_speed (all, except BSD) and libusb_error_name
63* Add Windows support (WinUSB driver only)
64* Add OpenBSD support
65* Add xusb sample
66* Tons of bug fixes
67
682010-05-07: v1.0.8
69* Bug fixes

712010-04-19: v1.0.7
72* Bug fixes and documentation tweaks
73* Add more interface class definitions
74

85 * More flexibility with clock types on Linux
86 * Use new bulk continuation tracking in Linux 2.6.32 for improved handling
87 of short/failed transfers

123APPENDIX A - How to maintain code compatibility with versions of libusb and
124libusbx that use MaxPower:
125
126If you must to maintain compatibility with versions of the library that aren't
127using the bMaxPower attribute in struct libusb_config_descriptor, the
128recommended way is to use the new LIBUSBX_API_VERSION macro with an #ifdef.
129For instance, if your code was written as follows:
130
131 if (dev->config[0].MaxPower < 250)
132
133Then you should modify it to have:
134
135#if defined(LIBUSBX_API_VERSION) && (LIBUSBX_API_VERSION >= 0x01000100)
136 if (dev->config[0].bMaxPower < 250)
137#else
138 if (dev->config[0].MaxPower < 250)
139#endif
