libusbx

libusbx is a library which provides generic access to USB devices. As a library, it is meant to facilitate the development of applications which communicate with USB hardware. Its main features are portability (a single cross-platform API for Linux, OS X, Windows, and *BSD), user-mode (no special privileges required), and USB version-agnosticism (all versions of the protocol supported, including USB 3.0).

        Release Notes: This releases adds hotplug support for Linux and OS X, auto-detach on Linux, and USB 3.0 descriptor support and strerror for all platforms. It also improves logging, zero-packet handling, topology, and descriptor parsing, and adds many bugfixes. Note that the libusb and libusbx projects are planning to merge back together, so the next release of libusbx is likely to occur under the libusb name.

            Release Notes: This release fixes major timeout-related bugs and broken support for the libusb-compat layer. It fixes a typo in the configuration descriptor structure, where MaxPower was used instead of bMaxPower, as per the USB specs. Support for the libusb-win32 and libusbK generic USB drivers has been added on Windows, and a new fxload sample, for Cypress FX/FX2 devices, has been introduced.
