Just came across this one. The author appears to be an active
user of libusb/libusbx judging from a few tickers he created.
https://bitbucket.org/liamstask/libusbus/overview
The motivation is kind of interesting. It seems to be a viable
alternative for people looking for a cut-down version of
libusb/libusbx and want a permissive license. It is not
as ambitious as the libusby project (which aims to be a
replacement of libusb/libusx).
1) More permissive license (MIT license)
2) Focus on device centric behavior and not interested in device
tree, kind of similar to libusb-win32
3) Only support WinUSB under Windows
4) Hotplug support
5) No locking or other thread management - leave this to the
application
6) As few heap allocations as possible
7) No isochronous transfer support since WinUSB does not
support isochronous transfer
8) Currently only Windows and Mac OS X support.
I actually have problems to build it under Mac OS X 10.7.5.
