Hi Ethan,
Hope you're keeping yourself amused down there!
At any rate, the trick to finding information on the Intel USB chip is
knowing the shorthand used to talk about the darned things. Since they're
not in production, this is becoming a lost art, it seems.
Try googling on 8x930xx - you'll get a number of good hits, including the
complete schematics for the Intel USB prototyping kit.
If you want chip docs, try googling on 8x930ax and one of the hits will be:
http://www.suid0.net/fhtw/doc/specs/ic/bridge/i8x930ax.pdf
which is the user's manual for the chip, all 16 chapters and 4 appendices
of it.
Whatever you discover, let me know--I still have most of a case of these
things...
Cheers,
Chuck
