I believe what you are seeing is the result of a problem I accidentally
introduced while making the probe routine more stable. The probe routine
is mistakenly rejecting your device because it's over-agressive about
sanity checking.
I have a fix. Unfortunately Randy rejected it because it also contained
some other things which seem to conflict with the UHCI driver.
I'm trying to get info on why that patch breaks with UHCI but not OHCI.
As soon as that's done, I'll resend the entire patch.
