Re: Help diagnosing USB disk issue?
Have you updated all of your usb drivers on that trouble machine yet?
If memory serves update-usb-ids ought to do that for you. Run by root
or something like root it's a script. Also, shut the trouble box down
and leave it off for an entire minute then reboot. Finally maybe
download the usbmount package and have that package run and see what it
finds for you. Try lsbusb -v too. Then lsscsi -v and see if you have
any new scsi drives. The usb drive may have moved to one of these.

The module uas isn't in 3.2.0-4, but is in 3.2.0-3, so I rebooted the X201 into kernel 3.2.0-3, modprobed uas (and uhci-hcd, for good measure), but still not recognizing the disk.
