Correct, this is a result of the unwillingness of the Linux kernel people
to create a uniform and integrated interface for all SCSI devices :-(

If they would at least be willing not to zero out important information
for ATAPI devices when trying to retrieve device instance data from the
kernel via /dev/hd*, it would be possible to integrate the unneeded
and non-orthogonal /dev/hd* interface. 

Your problem is entirely caused by the Linux Kernel folks, so please
complaint to them.....

So if you don't have this DVD writer in you system, what is your problem?
