The Pioneer CD changer is supposed to use "cd" and not "ch".  It
will shuffle between CDs when you access a different logical drive.
Each drive has its own LUN, and "scsiconf.c" has a special match
for "CD-ROM DRM-600" to support probing more than one LUN.

This used to work in 1.1.5.  In 2.0 Serge Goncharov
(joker@avangard.master.nsk.su) was having trouble getting it to
probe all the LUNS.  I'm not sure what the status is, I've sent
him some e-mail to find out.
