Comment 1 Michael K. Johnson 2000-08-04 16:19:07 EDT
Do you (don't laugh!) have a uhci USB controller?
("grep usb /etc/modules.com" will tell us the answer)
Comment 2 Joshua Buysse 2000-08-04 19:41:12 EDT
Yep.  'Tis UHCI.  Old Intel (remarked and re-biosed by Dell) LX board.
Comment 3 Michael K. Johnson 2000-08-07 09:45:43 EDT
OK, in /etc/modules.conf, change
alias usb-controller uhci
to
alias usb-controller usb-uhci

That should fix the problem; it does on all the
machines we have tested it on.  It appears to
be a bug in the uhci module that does not show
up in the usb-uhci module.  We have change our
configuration code to make usb-uhci the default
in the future.
