UUID for USB devices

[Geoffrey Leach]

Under Fedora 14 the following procedure worked for discovering the UUID 
for a USB device.

Insert device
Look in /dev/disk/by-label for device
Use file cmd to find device assigned
Look in /dev/disk/by-uuid for the UUID assigned (link to same device)

Alas, that no longer works. Anyone have an up-to-date procedure?

Thanks.
