Yes, I also decided to going with solution stiw47 to uucp group instead to creating some udev rule that stiw47 always being owner of ttyUSB0.

Btw, AUR maintainer informed: https://aur.archlinux.org/pack…on.ng-git/#comment-840237

There was a issue where the ttyUSB0 had a permissions issue for a user cause it was just on root.

I have the exact same issue.

kodi@kodi-mediacentre:~$ ls -al /dev/ttyACM0

crw-rw---- 1 root dialout 166, 0 Jun 9 06:13 /dev/ttyACM0

i have taken then the user kodi and moved it into the dialout group

dialout:x:20:kodi

But when i do the command ls -al /dev/ttyACM0 the user kodi is stil no there.

I then did and it worked but if i restart im back to root

kodi@kodi-mediacentre:~$ ls -al /dev/ttyACM0

crw-rw---- 1 kodi dialout 166, 0 Jun 9 06:13 /dev/ttyACM0

any linux gurus that can help me out?
