I use a lot of tapes but never a USB, but from my knowledge I would try

 lsusb

then read the output and look at the id's, find the one that
has the usb tape drive attached to it, then use

 lsusb -vv

and find the matching id to get more info.

You could also try:

 modprobe usb_storage

then

 modbrobe st

and then do 

  "lsmod | grep storage"
  "lsmod | grep st"

that they are loaded (st should require to load the scsi stuff too).
You could also look into /dev and look at the major numbers (from
memory 9 is tapes??).

  ls -al /dev/tape/by-id

and

  ls -la /dev/.udev

and look through all of those.

check whether there is something with "usb-st" or so.
