35 * Multiple OS X improvements (broken compilation, SIGFPE, 64bit support)
38 * Hotplug callbacks now always get passed a libusb_context, even if it is
39 the default context. Previously NULL would be passed for the default context,
40 but since the first context created is the default context, and most apps
41 use only 1 context, this meant that apps explicitly creating a context would
43 * Android: Add .mk files to build with the Android NDK
44 * Darwin: Add Xcode project
45 * Darwin: Fix crash on unplug (#121)

85 * Add SuperSpeed detection on OS X
86 * Fix bInterval value interpretation on OS X
87 * Fix issues with autoclaim, composite HID devices, interface autoclaim and
88 early abort in libusb_close() on Windows. Also add VS2012 solution files.
89 * Improve fd event handling on Linux
90 * Other bug fixes and improvements
93 * Reverts the previous API change with regards to bMaxPower.
94 If this doesn't matter to you, you are encouraged to keep using v1.0.13,
95 as it will use the same attribute as v2.0, to be released soon.
96 * Note that LIBUSB_API_VERSION is *decreased* to 0x010000FF and the previous
97 guidelines with regards to concurrent use of MaxPower/bMaxPower still apply.
100 * [MAJOR] Fix a typo in the API with struct libusb_config_descriptor where
101 MaxPower was used instead of bMaxPower, as defined in the specs. If your
102 application was accessing the MaxPower attribute, and you need to maintain
103 compatibility with libusb or older versions, see APPENDIX A below.
104 * Fix broken support for the 0.1 -> 1.0 libusb-compat layer
105 * Fix unwanted cancellation of pending timeouts as well as major timeout related bugs
106 * Fix handling of HID and composite devices on Windows
107 * Introduce LIBUSB_API_VERSION macro
108 * Add Cypress FX/FX2 firmware upload sample, based on fxload from
109 http://linux-hotplug.sourceforge.net
110 * Add libusb0 (libusb-win32) and libusbK driver support on Windows. Note that while
111 the drivers allow it, isochronous transfers are not supported yet in libusb. Also
112 not supported yet is the use of libusb-win32 filter drivers on composite interfaces
113 * Add support for the new get_capabilities ioctl on Linux and avoid unnecessary
114 splitting of bulk transfers

121 * Fix missing thread ID from debug log output on cygwin
122 * Fix possible crash when using longjmp and MinGW's gcc 4.6
123 * Add topology calls: libusb_get_port_number(), libusb_get_parent() & libusb_get_port_path()
124 * Add toggleable debug, using libusb_set_debug() or the LIBUSB_DEBUG environment variable
125 * Define log levels in libusb.h and set timestamp origin to first libusb_init() call
126 * All logging is now sent to to stderr (info was sent to stdout previously)
127 * Update log messages severity and avoid polluting log output on OS-X
128 * Add HID driver support on Windows
129 * Enable interchangeability of MSVC and MinGW DLLs
130 * Additional bug fixes and improvements

211 APPENDIX A - How to maintain code compatibility with versions of libusb and
212 libusb that use MaxPower:
214 If you must to maintain compatibility with versions of the library that aren't
215 using the bMaxPower attribute in struct libusb_config_descriptor, the
216 recommended way is to use the new LIBUSB_API_VERSION macro with an #ifdef.
217 For instance, if your code was written as follows:
219 if (dev->config[0].MaxPower < 250)
221 Then you should modify it to have:
223 #if defined(LIBUSB_API_VERSION) && (LIBUSB_API_VERSION >= 0x01000100)
224 if (dev->config[0].bMaxPower < 250)
226 if (dev->config[0].MaxPower < 250)
