Interesting! The command just hangs. In my kernel log:
Nov 8 16:04:02 teufel kernel:

Nov 8 16:04:02 teufel kernel:

This goes on to block 9, and then repeats. It's almost as if there
were some kind of physical damage. I'm not sure how to get the Sense
Key error number, as that might help, although the advice generally
relates to SCSI disks.
When I try:
$ lsusb -v -D /dev/sdd
Cannot open /dev/sdd
When I plug in the usb-key, the kernel log sayw:
