This struct and libusb_get_device_descriptor() method are not present
in libusb-0.1 API, so when libusb-1.0 is unavailable, this code breaks
the build. Fix by using the appropriate struct (which is apparently
filled automatically on device initialisation).
While at it, change return values for consistency with the callers.
