#This file provides some example udev rules which may be helpful for comedi.
#It includes rules for creating symlinks to the device file with
#persistent names in /dev/comedi/by-id/, setting permissions and
#group ownership on the comedi device files, and examples showing
#adjustment of a device file's buffer size.
