To the HPLIP developers at HP: The "hp" and "hpfax" backends seem not to
handle gracefully the case if they are run on a computer without USB or
if the USB kernel modules are not loaded (server/high security
environments). libusb fails to initialize but the HP backends try to
access the connection which libusb failed to establish.
If libusb initialization fails, the backend should skip the USB printer
detection with an empty result.
