Within libusb 0.1 API, bus number is always faked to 0. Device numbers,
 however, are possitive and seem to be reverse sorted in the list.

 Conform device numbering and bring a result that is consistent with the
 libusb 0.1 API.  It is now possible to distinguish a device based on its
 (bus, dev) numbers.
