i have a similar situation with heyu, which runs as a normal user. But
udev insists all the ttyUSB# ports are root:root, so I've put a couple
lines in my rc.local for the last decade or so to make me own, with 0666
rights, the port the cm11a is plugged into. heyu then fires itself up as
me and works, doing its job of managing the exterior lights around my
home at night.
You may have to resort to similar measures.
