When I put my external DVD drive on my computer the devices look like this: ---snip--- /dev/dvd -> /dev/cd/dvd-4:0:0:0 /dev/cd/dvd- -> /dev/sr0 ---snip--- I can access the drive via /dev/sr0, /dev/cd/dvd- and even /dev/scd0 but not via /dev/dvd, because of the wrong enty in /dev/cd This what I got from the debug messages: ---snip--- Nov 17 23:27:43 proton udevd-event[3301]: '/dev/cd/cdrom-' with target '/dev/sr0' has the highest priority 0, create it Nov 17 23:27:43 proton udevd-event[3301]: creating symlink '/dev/cd/cdrom-' to '../sr0' Nov 17 23:27:43 proton udevd-event[3301]: '/dev/cd/cdrw-' with target '/dev/sr0' has the highest priority 0, create it Nov 17 23:27:43 proton udevd-event[3301]: creating symlink '/dev/cd/cdrw-' to '../sr0' Nov 17 23:27:43 proton udevd-event[3301]: '/dev/cd/dvd-' with target '/dev/sr0' has the highest priority 0, create it Nov 17 23:27:43 proton udevd-event[3301]: creating symlink '/dev/cd/dvd-' to '../sr0' Nov 17 23:27:43 proton udevd-event[3301]: update old symlink '/dev/cd/cdrom-4:0:0:0' no longer belonging to '/devices/pci0000:00/0000:00:1d.7/usb1/1-2/1-2:1.0/host4/target4:0:0/4:0:0:0/block/sr0' Nov 17 23:27:43 proton udevd-event[3301]: no reference left, remove '/dev/cd/cdrom-4:0:0:0' Nov 17 23:27:43 proton udevd-event[3301]: update old symlink '/dev/cd/cdrw-4:0:0:0' no longer belonging to '/devices/pci0000:00/0000:00:1d.7/usb1/1-2/1-2:1.0/host4/target4:0:0/4:0:0:0/block/sr0' Nov 17 23:27:43 proton udevd-event[3301]: no reference left, remove '/dev/cd/cdrw-4:0:0:0' Nov 17 23:27:43 proton udevd-event[3301]: update old symlink '/dev/cd/dvd-4:0:0:0' no longer belonging to '/devices/pci0000:00/0000:00:1d.7/usb1/1-2/1-2:1.0/host4/target4:0:0/4:0:0:0/block/sr0' Nov 17 23:27:43 proton udevd-event[3301]: no reference left, remove '/dev/cd/dvd-4:0:0:0' ---snip--- The right entries are removed in favour of the wrong entries and I have no idea why that is. Since I can't find the creation of this symlink anywhere in the udev scripts. I use the current udev version and the hal version from testing. But I think it is related to this rule in 81-arch.rules: ---snip--- ENV{ID_CDROM}=="?*", SYMLINK+="cd/cdrom-%b" ENV{ID_CDROM_CD_RW}=="?*", SYMLINK+="cd/cdrw-%b" ENV{ID_CDROM_DVD}=="?*", SYMLINK+="cd/dvd-%b" ENV{ID_CDROM_DVD_R}=="?*", SYMLINK+="cd/dvd-%b" ---snip--- The variable %b is missing. Where does this rule file gets its variables? I hope someone can help me. Thomas
