Hi Ethan,
At any rate, the trick to finding information on the Intel USB chip is
knowing the shorthand used to talk about the darned things...
Try googling on 8x930xx - you'll get a number of good hits, including the
complete schematics for the Intel USB prototyping kit.
Ah... that helps loads.
Unfortunately, the chip is so old that many of the 'hits' I've found
are dead ends.
This one in particular looked interesting, but it's not there anymore. :-(

If you want chip docs, try googling on 8x930ax and one
of the hits will be:

Wow! That's a detailed reference - I think it'll be handy to
reverse-engineer the I/O on the board (switches, LEDs, and rotary
encoder).
