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...
