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.
