If you suspect libusb-1.0 and you may well be correct since the
older 1.0.8 is buggy and 1.0.9 was only released a few days ago
after the fork libusbx announced. You should try libusb-1.0.9
or the fork libusbx-1.0.10 to see if they solve your problem.
One of the libusb-1.0.8 bugs which has caused many problem
for people running Linux: http://www.libusb.org/ticket/56
