Do not use the plugdev group
In the rules file, there is this line:
SUBSYSTEM=="usb|input|hid", GROUP:="plugdev"
But Arch doesn't have such group, as it is discouraged in the Wiki. Hence the driver will only work by adding the discouraged group (with sudo gpasswd -a $USER plugdev).
Shall we notify this upstream too?
