hmmm, does the same for me.  Strange thing is that I use the
/usr/local/sbin/mtx-changer in my bacula-sd.conf which uses the mtx
script!!  Also, it looks like the correct usage is "inquiry":-
------snip----
Usage:
  mtx --version
  mtx [ -f <loader-dev> ] noattach <more commands>
  mtx [ -f <loader-dev> ] inquiry | inventory
  mtx [ -f <loader-dev> ] [nobarcode] status
  mtx [ -f <loader-dev> ] first [<drive#>]
  mtx [ -f <loader-dev> ] last [<drive#>]
  mtx [ -f <loader-dev> ] next [<drive#>]
  mtx [ -f <loader-dev> ] previous [<drive#>]
  mtx [ -f <loader-dev> ] [invert] load <storage-element-number> [<drive#>]
  mtx [ -f <loader-dev> ] [invert] unload
[<storage-element-number>][<drive#>]
  mtx [ -f <loader-dev> ] [eepos eepos-number] transfer
<storage-element-number> <storage-element-number>
  mtx [ -f <device> ] eject
------snip----


However, this fails too:-
# mtx -f /dev/ch0 inquiry
cannot open SCSI device '/dev/ch0' - Inappropriate ioctl for device
 
But this works:-
# mtx -f /dev/pass1 inquiry
Product Type: Medium Changer
Vendor ID: 'OVERLAND'
Product ID: 'LXB             '
Revision: '0106'
Attached Changer: No

Just for info, my scsi devices look like this:-
# camcontrol devlist
<PE/PV 1x6 SCSI BP 1.0>            at scbus0 target 6 lun 0 (pass0,ses0)
<OVERLAND LXB 0106>                at scbus2 target 14 lun 0 (pass1,ch0)
<HP Ultrium 2-SCSI F6CH>           at scbus2 target 15 lun 0 (pass2,sa0)

Not sure why it claims that there is no changer though.
