dgrp_gui will not use group id and access mode. Always creates with 0 and 600. How can I change these?

Using PortServer TS H MEI (4 ports) with Linux SUSE 11.3. I don’t want to run my application with superuser privilege, but devices are created with group as root and access as 600. I have tried to use dgrp_gui to change the group and access but it always creates devices with root (0) and access (600) no matter what I enter. Is there a way to change the group and access when the devices are created?

With modern versions of Linux utilizing UDEV, you will need to modify the udev rules file:
