Can you remind me what the side effects would be if a different
VID/PID shows up there? I know it's not an end-user scenario, but I
have a pre-production "coachz" keyboard that's actually programmed
incorrectly and shows up as the wrong PID. Presumably I could either
throw the old hardware away or figure out a way to re-program it and
it's really not a big deal, but just curious what happens...
