Is that Via chip reporting as OHCI 1.0 or 1.1? Trying to prove out my
theory that OHCI 1.1's dual-buffer isochronous receive is generally
boned...

Also, while similar, the TSB43AB23 and TSB43AB22/A are unique, and one
or the other has some nasty errata bug I can't recall the details of
offhand.

In 2.6.33, dual-buffer iso receive is going to be universally disabled
by default even on 1.1 controllers, and everyone will just do
packet-per-buffer.
