Hey,

I've some problems setting up the udev rules for my cdrom-drive. Actually the settings should work but the /dev/cdrom device is always linked to /dev/sda2 though my cdrom is /dev/hdb.

lrwxrwxrwx 1 root root 4 Dec 27 17:10 /dev/cdrom -> sda2
brw-rw---- 1 root disk 3, 64 Dec 27 17:10 /dev/hdb

my udev-rules look like this:

ACTION="add", SUBSYSTEM="block", ENV(ID_TYPE)="cd", SYMLINK+="cdrom dvd", GROUP="cdrom"

I've already tried to use ENV(ID_MODEL) and ENV(ID_SERIAL) but it didnt worked either.

I've noticed that it doesnt take any effect if I comment this rule, so maybe udev doesnt recognize it. The rule is placed in /etc/udev/rules.d/82-cdrom.rules, the same place where all the other rules are.

So maybe Im just too stupid to see the failure or maybe its a but. I hope someone of you can help me.

Thanks in advance,

Jonathan

How about this one?
Replace from ( ) to { }.

ACTION="add", SUBSYSTEM="block", ENV{ID_TYPE}="cd", SYMLINK+="cdrom dvd", GROUP="cdrom"
^ ^
