The default udev rules don't seem to include anything for parallel port cdrom drives, meaning that on my system, /dev/pcd0 is given the wrong group (disk rather than cdrom) and pg0 has the wrong group (root) and permissions (600 rather than 660); I also get no /dev/cdrom symlink. A copy of the scsi rules with "s" changed to "p", viz: KERNEL="pcd[0-9]*", ACTION=="add", IMPORT="/sbin/cdrom_id --export $tempnode" KERNEL="pg[0-9]*", ACTION=="add", GROUP="cdrom" (I am unsure what the BUS should be) immediately following BUS=="scsi", KERNEL="sr[0-9]*", ACTION=="add", IMPORT="/sbin/cdrom_id --export $tempnode" BUS=="scsi", KERNEL="scd[a-z]", ACTION=="add", IMPORT="/sbin/cdrom_id --export $tempnode" BUS=="scsi", KERNEL="sg[0-9]*", ACTION=="add", DRIVER=="sr", GROUP="cdrom" appears to fix this.

Care to attach a patch to the 50-udev.rules file for this?
