can't change ownerhip of parport0

ZaphyR · 08-10-2006, 04:30 PM

I have recently installed Suse 10.1 on my fathers laptop, and he has old scanner he wants to use. The scanner uses the parallel port, not usb.

I managed to install the drivers, and test the scanner, it works perfectly. Only thing is that the ownership of parport0 changes to root:root after every reboot. I use chown to change it to XXXX:users but it always goes returns to root.

How can I permanently change the ownership, or group, of /dev/parport0?

Change the udev rules for parport[0-9]. Should just be able to change the group from root to users in the rules file but not sure when it's located in Suse, try somewhere in /etc/udev.

I created a file called 10-local.rules under /etc/udev/rules.d/ and added the following line:

Code:

KERNEL=="parport[0-9]*", GROUP="users"

so now a ls -l /dev/parport0 shows this:

Code:

crw-rw---- 1 root users

Scanning now works perfectly as user as well!

Thanks!
