It may also be a permissions problem (as I'd recently suffered with
debian-weezy, and got resolved in the last  debian upgrade).

If Dirk's solution doesn't work give a try to:

   #chmod a+rw /dev/ttyUSB0      (as root)

If it works after this, you have to get permissions for the next
sessions, usually including your user in the group which ubuntu assigns
to the device.
