Ok, but in core.py, the search order seems to put OpenUSB ahead of libusb01,
such that if a particular machine has all three libraries, it will go to
openusb, which you say, whose backend wrapper is not quite ready yet.
Would it not be better to change the search order to put OpenUSB at the end?
(for now)
if backend is None:
import usb.backend.libusb10 as libusb10
import usb.backend.libusb01 as libusb01
import usb.backend.openusb as openusb
for m in (libusb10, openusb, libusb01):
backend = m.get_backend()
if backend is not None:
_logger.info('find(): using backend "%s"', m.__name__)
break
