True, and you can use that and other hints (vendor & device Ids or strings and so forth), but you can't count on people plugging the pad back into the same port (my living room PC has something like 14 USB ports, and they are around the back where I can't see them).

Once you get into Bluetooth controllers where there is no physical wire...
