SuSe would do this mounting/unmounting for you.  (Is it still called 
supermount?
or something else).

Do a "dmesg" or "cat /var/log/messages" right after you plug the device 
in.  It
should say what device it is assigned to - since this is dynamic it may not be
the same every time.  I've seen distros that don't recycle so if you
plug/unplug/plug/unplug/plug you get sdb... sdc... sdd... etc...
