However the libusb1 is not working yet (I tested the HID backend and
it is not working with interrupt read/write. I have not tested the WinUSB
backend under XP). And WinUSB is only for Vista/XP.
Under Win98SE/Win2k/WinXp, it is still better to use libusb-win32
device driver. So I think your patch is still useful.

Any examples of dealing with WM_DEVICECHANGE with your patched
version of libusb-win32 and your C# wrapper?
