The wacom driver accepts devices of more than just USB types, but some code paths can cause problems if the device being controlled is not a USB device due to a lack of checking. Add the needed checks to ensure that the USB device accesses are only happening on a "real" USB device, and not one on some other bus.

Many HID drivers assume that the HID device assigned to them is a USB device as that was the only way HID devices used to be able to be created in Linux. However, with the additional ways that HID devices can be created for many different bus types, that is no longer true, so properly check that we have a USB device associated with the HID device before allowing a driver that makes this assumption to claim it.
