I must say I'm not an expert, but I have been using a USB cdrom (actually
cdrw), and I'm a little surprised that yours is on /dev/sr0. I don't know
what that device corresponds to, but perhaps you could try /dev/scd0 (which
should be the first scsi cd-rom drive, and the usb drive pretends to be a
cd-rom). This is only a guess, though, but I figured I'd point it out
since it's a difference between what you did and what I did.

Hmmm. This is a kernel I was using until recently, and had no problems...

I'm afraid I may not have been very helpful, but perhaps switching to
/dev/scd0 will do the trick. If not, then I'm at a loss.
