It is really strange it is working with official 0.4.2 version but not
with 0.1 backend. Specially because it can load the shared library,
but cannot find any test device... If you want to force usb.legacy to
use libusb01 backend, we must change legacy.py module, change line 322
to
import usb.backend.libusb01 as libusb01
self.devices = [Device(d) for d in core.find(find_all=True,
backend=libusb01.get_backend())]
