Hello all,
I have set a box for a friend running Kubuntu 16.04 with a brother MF7680DW multifunction printer/scanner attached via usb. I have installed the latest drivers from the Brother website and the printer works fine but the scanner is not found by any scanning program.
Research indicates that there is a permissions issue error. 

The solution is to run sudo chmod 666 /dev/bus/usb/001/002 which fixes the usb bus permissions problem and the scanner is found.

Am I able to place this command somewhere so that it is executed on startup? How do I overcome the issue of needing root access?
