The GPL v non-GPL is intended to help identify stuff that is clearly GPL
only use from stuff that is "maybe". You get into an area of law called
"derived works" which is to say the least full of grey areas in this zone.
Essentially there isn't any caselaw to guide people _yet_.

For the USB driver case there is libusb anyway
