First off I do apologise for cross posting if it inconveniences
anyone; but the three groups seemed pertinent to the topic...

I'm trying to get USB to work on an UltraSparc5 running -current and 2.0

I bought the generic USB PCI card, which shows up as:

uhci0 at pci2 dev 3 function 0: VIA Technologies VT83C572 USB
Controlller (rev 0x50)
uhci0: interrupting at ivsec 18
usb0 at uhci0: USB revision 1.0
uhub0 at usb0
uhub0: VIA Technologies UHCI root hub class 9/0, rev 1.00/1.00, addr 1
uhub0: 2 ports with 2 removable, self powered

(same as above for uhub1).

ehci0 doesn't work, so I recompiled the kernel without.

Anyway, the above looks fine, but I'm not getting any entries in
/var/log/messages or on the console when I plug in various USB devices
(memory sticks etc). It's as if there is no response from the USB

How could I debug this or find out what's going wrong?

I found

but it had a broken link for the PR, and other messages for the same
controller don't have the symptons as above.

Many thanks for any ideas to get this working,
