I join you an answer of the SCSI maintainer in addition to the excellents advices John P. gave. Hope it will help.

It caused trouble to more people than to you.

Me neither. Almost certainly some Yamaha firmware misfunction. > * Started (a month ago) w/kernel 2.0.36 from debian's CD: YAMAHA causes > troubles, zapped from system (I was obliged to cut-off the main power supply > to > recover it in the system!): The DC390 was recognized as AM53C974, Then you used the AM53C974 driver. Well it's buggy, if you allow disconnection, so I'd prefer not to use it. Unfortunately, it's also unmaintained. > * Recompiled the kernel w/only the DC390: DC390 was recognized as DC390, > YAMAHA > CR was not recognized, > > * Upgrade to 2.2.1: always no recognition of the CDR (not seen by the driver) > > * Upgrade to 2.2.7: still the same! It's the same driver in those kernel, so the behaviour must be the same. Here's the band aid: Become root and type echo "scsi add-single-device 0 0 5 0" >/proc/scsi/scsi cat /proc/scsi/scsi Your CD-R will be detected. Please read the web page http://www.garloff.de/kurt/linux/dc390/problems.html for more information.
