Are you sure about that changerdev?  For my Overland changer, the tape 
drive and robotics have separate SCSI IDs.  The tape drive is ID 4, and 
the robotics are ID 6.  Therefore the tape drive is sg0, and the robotics 
are sg1.

First, can mtx talk to your changer?  What's the output of 'mtx -f 
/dev/sg0 status' (or sg1, as above).

If the device is correct, we'll need to see your CHANGER.conf file.
