Libusb

* Add support for USB bulk streams on Linux and Mac OS X (11)
* Windows: Add AMD and Intel USB-3.0 root hub support
* Windows: Fix USB 3.0 speed detection on Windows 8 or later (10)
* Added Russian translation for libusb_strerror strings
* All: Various small fixes and cleanups

* Fix multiple memory leaks
* Fix a crash when HID transfers return no data on Windows
* Ensure all pending events are consumed
* Improve Android and ucLinux support
* Multiple Windows improvements (error logging, VS2013, VIA xHCI support)
* Multiple OS X improvements (broken compilation, SIGFPE, 64bit support)

* Hotplug callbacks now always get passed a libusb_context, even if it is
the default context. Previously NULL would be passed for the default context,
but since the first context created is the default context, and most apps
use only 1 context, this meant that apps explicitly creating a context would
still get passed NULL
* Android: Add .mk files to build with the Android NDK
* Darwin: Add Xcode project
* Darwin: Fix crash on unplug (121)
* Linux: Fix hang (deadlock) on libusb_exit
* Linux: Fix libusb build failure with --disable-udev (124)
* Linux: Fix libusb_get_device_list() hang with --disable-udev (130)
* OpenBSD: Update OpenBSD backend with support for control transfers to
non-ugen(4) devices and make get_configuration() no longer generate I/O.
Note that using this libusb version on OpenBSD requires using
OpenBSD 5.3-current or later. Users of older OpenBSD versions are advised
to stay with the libusb shipped with OpenBSD (mpi)
* Windows: fix libusb_dll_2010.vcxproj link errors (129)
* Various other bug fixes and improvements

* Add hotplug support for Darwin and Linux (9)
* Add superspeed endpoint companion descriptor support (15)
* Add BOS descriptor support (15)
* Make descriptor parsing code more robust
* New libusb_get_port_numbers API, this is libusb_get_port_path without
the unnecessary context parameter, libusb_get_port_path is now deprecated
* New libusb_strerror API (14)
* New libusb_set_auto_detach_kernel_driver API (17)
* Improve topology API docs (95)
* Logging now use a single write call per log-message, avoiding log-message
"interlacing" when using multiple threads.
* Android: use Android logging when building on Android (101)
* Darwin: make libusb_reset reenumerate device on descriptors change (89)
* Darwin: add support for the LIBUSB_TRANSFER_ADD_ZERO_PACKET flag (91)
* Darwin: add a device cache (112, 114)
* Examples: Add sam3u_benchmark isochronous example by Harald Welte (109)
* Many other bug fixes and improvements
The (xx) numbers are libusbx issue numbers, see ie:
https://github.com/libusbx/libusbx/issues/9

* Improve transfer cancellation and avoid short read failures on broken descriptors
* Filter out 8-bit characters in libusb_get_string_descriptor_ascii()
* Add WinCE support
* Add library stress tests
* Add Cypress FX3 firmware upload support for fxload sample
* Add HID and kernel driver detach support capabilities detection
* Add SuperSpeed detection on OS X
* Fix bInterval value interpretation on OS X
* Fix issues with autoclaim, composite HID devices, interface autoclaim and
early abort in libusb_close() on Windows. Also add VS2012 solution files.
* Improve fd event handling on Linux
* Other bug fixes and improvements

* Reverts the previous API change with regards to bMaxPower.
If this doesn't matter to you, you are encouraged to keep using v1.0.13,
as it will use the same attribute as v2.0, to be released soon.
* Note that LIBUSB_API_VERSION is *decreased* to 0x010000FF and the previous
guidelines with regards to concurrent use of MaxPower/bMaxPower still apply.
