mounting fake cd-roms that are on usb sticks

I have USB stick that presents as both a CD-ROM drive and a regular drive.
(Why?  I guess so that the CD-ROM part cannot be modified.)

The regular drive is detected, shows up on the desktop, and is mounted fine.
However, the CD-ROM part does not even show up on the desktop and the only way
I can figure out to mount it is `sudo mount /dev/sr0 /mnt`.

I would like to have this drive to at least show up on the desktop, and
preferably be automounted.  Does anyone know how to do this?


PS:  Here is an edited system log of what happens when the stick is plugged in.
