5 * Add support for USB bulk streams on Linux and Mac OS X (#11)
6 * Windows: Add AMD and Intel USB-3.0 root hub support
7 * Windows: Fix USB 3.0 speed detection on Windows 8 or later (#10)
8 * Added Russian translation for libusb_strerror strings
9 * All: Various small fixes and cleanups
10 The (#xx) numbers are libusb issue numbers, see ie:
11 https://github.com/libusb/libusb/issues/11
14 * Fix multiple memory leaks
15 * Fix a crash when HID transfers return no data on Windows
16 * Ensure all pending events are consumed
17 * Improve Android and ucLinux support
18 * Multiple Windows improvements (error logging, VS2013, VIA xHCI support)
19 * Multiple OS X improvements (broken compilation, SIGFPE, 64bit support)
22 * Hotplug callbacks now always get passed a libusb_context, even if it is
23 the default context. Previously NULL would be passed for the default context,
24 but since the first context created is the default context, and most apps
25 use only 1 context, this meant that apps explicitly creating a context would
27 * Android: Add .mk files to build with the Android NDK
28 * Darwin: Add Xcode project
29 * Darwin: Fix crash on unplug (#121)
30 * Linux: Fix hang (deadlock) on libusb_exit
31 * Linux: Fix libusb build failure with --disable-udev (#124)
32 * Linux: Fix libusb_get_device_list() hang with --disable-udev (#130)
33 * OpenBSD: Update OpenBSD backend with support for control transfers to
34 non-ugen(4) devices and make get_configuration() no longer generate I/O.
35 Note that using this libusb version on OpenBSD requires using
36 OpenBSD 5.3-current or later. Users of older OpenBSD versions are advised
37 to stay with the libusb shipped with OpenBSD (mpi)
38 * Windows: fix libusb_dll_2010.vcxproj link errors (#129)
39 * Various other bug fixes and improvements
42 * Add hotplug support for Darwin and Linux (#9)
43 * Add superspeed endpoint companion descriptor support (#15)
44 * Add BOS descriptor support (#15)
45 * Make descriptor parsing code more robust
46 * New libusb_get_port_numbers API, this is libusb_get_port_path without
47 the unnecessary context parameter, libusb_get_port_path is now deprecated
48 * New libusb_strerror API (#14)
49 * New libusb_set_auto_detach_kernel_driver API (#17)
50 * Improve topology API docs (#95)
51 * Logging now use a single write call per log-message, avoiding log-message
52 "interlacing" when using multiple threads.
53 * Android: use Android logging when building on Android (#101)
54 * Darwin: make libusb_reset reenumerate device on descriptors change (#89)
55 * Darwin: add support for the LIBUSB_TRANSFER_ADD_ZERO_PACKET flag (#91)

68 * Add HID and kernel driver detach support capabilities detection
69 * Add SuperSpeed detection on OS X
70 * Fix bInterval value interpretation on OS X
71 * Fix issues with autoclaim, composite HID devices, interface autoclaim and
72 early abort in libusb_close() on Windows. Also add VS2012 solution files.
73 * Improve fd event handling on Linux
74 * Other bug fixes and improvements
77 * Reverts the previous API change with regards to bMaxPower.
78 If this doesn't matter to you, you are encouraged to keep using v1.0.13,
79 as it will use the same attribute as v2.0, to be released soon.
80 * Note that LIBUSB_API_VERSION is *decreased* to 0x010000FF and the previous
81 guidelines with regards to concurrent use of MaxPower/bMaxPower still apply.
84 * [MAJOR] Fix a typo in the API with struct libusb_config_descriptor where
85 MaxPower was used instead of bMaxPower, as defined in the specs. If your
86 application was accessing the MaxPower attribute, and you need to maintain
87 compatibility with libusb or older versions, see APPENDIX A below.
88 * Fix broken support for the 0.1 -> 1.0 libusb-compat layer
89 * Fix unwanted cancellation of pending timeouts as well as major timeout related bugs
90 * Fix handling of HID and composite devices on Windows
91 * Introduce LIBUSB_API_VERSION macro
92 * Add Cypress FX/FX2 firmware upload sample, based on fxload from
93 http://linux-hotplug.sourceforge.net
94 * Add libusb0 (libusb-win32) and libusbK driver support on Windows. Note that while
95 the drivers allow it, isochronous transfers are not supported yet in libusb. Also
96 not supported yet is the use of libusb-win32 filter drivers on composite interfaces
97 * Add support for the new get_capabilities ioctl on Linux and avoid unnecessary
98 splitting of bulk transfers
99 * Improve support for newer Intel and Renesas USB 3.0 controllers on Windows
100 * Harmonize the device number for root hubs across platforms

106 * Fix possible crash when using longjmp and MinGW's gcc 4.6
107 * Add topology calls: libusb_get_port_number(), libusb_get_parent() & libusb_get_port_path()
108 * Add toggleable debug, using libusb_set_debug() or the LIBUSB_DEBUG environment variable
109 * Define log levels in libusb.h and set timestamp origin to first libusb_init() call
110 * All logging is now sent to to stderr (info was sent to stdout previously)
111 * Update log messages severity and avoid polluting log output on OS-X
112 * Add HID driver support on Windows
113 * Enable interchangeability of MSVC and MinGW DLLs
114 * Additional bug fixes and improvements
117 * Revert removal of critical Windows event handling that was introduced in 1.0.10

195 APPENDIX A - How to maintain code compatibility with versions of libusb and
196 libusb that use MaxPower:
198 If you must to maintain compatibility with versions of the library that aren't
199 using the bMaxPower attribute in struct libusb_config_descriptor, the
200 recommended way is to use the new LIBUSB_API_VERSION macro with an #ifdef.
201 For instance, if your code was written as follows:
203 if (dev->config[0].MaxPower < 250)
205 Then you should modify it to have:
207 #if defined(LIBUSB_API_VERSION) && (LIBUSB_API_VERSION >= 0x01000100)
208 if (dev->config[0].bMaxPower < 250)
210 if (dev->config[0].MaxPower < 250)
