Really? Every USB drive I have used shows up as a SCSI device. They
usually have one partition, and for thumb drives it is normally the
first partition that is used. So it would be something like
/dev/sda1, /dev/sdb1, /dev/sdc1, ect. The drive letter depends on
the number of other SCSI drives. If you do a lot if
plugging/unplugging of drives is a short period, you may have a gap
in the letters. You may have a sdb1 without a sda1, or sda1 and
sdc1, without a sdb1.
With USB ZIP drives, it is another story - a lot of the ZIP disks
are set up to use partition 4, so you end up mounting /dev/sdb4
instead of /dev/sdb1.
To make things more interesting, IDE drives in an external USB case
will also show up as a SCSI drive. I believe that SCSI emulation is
used with all USB and Firewire drives, but I could be wrong...
