Thank you; neither of the vid/pid pairs in the original submission is
okay. I'll follow up with an updated version.

I've also checked this on RPi B rev2; and I'll be including that one,
and the RPI2 too.

I can't find my rev1 RPi B; but maybe I can just do the same for the
same board. It would likely work, but I may get the vid/pid wrong if
it's different from rev2.
