That's on an ASUS CUV4X with 4 USB ports on the main board. Moving
things between ports do not make a difference - the mouse still works
and the disk does not. Perhaps the the flaky part i s the USB port in the
disk side. I could never make it work thru a hub - but then
it initialized correctly and failed only during data transfer.

I just put a scanner on he same system. The scanner is working OK
where the disk has failed.

Again, I do not see the disk usind usbview (or in /proc/bus/usb/devices)
so I believe the problem is more with detection than with initialization.
