Thanks, Nathan,
dmesg | grep -i usb (I added the -i, as I ran into this on the CDROM howto)
shows
usb.c: registered new driver usbdevfs
usb.c: registered new driver hub
usb.c: registered new driver hid
hid-core.c: USB HID support drivers
and nothing more. I tried modprobe again:
modprobe usb-ohci
modprobe: Can't locate module usb-ohci
likewise for usb-uhci
You do remember correctly. The 8500 has no built-in USB ports. This is a
$10 special, no-name board, which the hardware browser says the
manufacturer is VIA technologies and that it is to use the usb-uhci
Driver, although it does appear from the dmesg command, it hasn't found.
