Craig,

Sorry for the incredibly late response.  General busyness you know.

You are of course correct sir.  See below.

Ignorance mostly.  This being the first machine I've ever had with USB
on it, I wasn't aware that USB 2.0 was handled by EHCI instead of the
OHCI or UHCI drivers (EHCI doesn't appear in the NOTES file and I
didn't think to make LINT until just a few minutes ago).  Once I
configured EHCI into the kernel all was well, and with your patch
it works swimmingly since it's even identified precisely.

So I for one can confirm that the patch you gave does indeed work.
Now if only I had the cash to buy a USB device to plug into the PC...

Thanks,
Brent Casavant
