Yes it does.  Well maybe.  /dev/sg1 (my changer) and /dev/sg2 (my tape

I have nada experience with a changer, but I believe that you access
a tapedrive of a changer to read/write/rewind etc through the "st"
kernel module, and hence you need to access the /dev/st0 (or whatever
number gave the kernel).
The changer mechanism (advance slot, etc) is accessed through the
generic scsi module "sg", and needs the /dev/sg1 device to interact.

Of course I could be wrong.
