I always scratch my head when I read things like this. Most CD/DVD writers are not SCSI devices these days. USB devices, too are not SCSI devices. Yet very often it turns out that in Linux anyway, these devices depend intimately on the kernel SCSI subsystem and end up with /dev/sd sorts of names. In 2.4 this was a convenient hack. Are there any pointers to how this is being tidied up in the brave new wold of 2.6? Or is the scsi subsystem still doubling up as a convenient generic block device service?
