(Handy) udev RULES

chmod ttyUSB and ttyACM

(handy for running things like Arduino IDE as a regular user)

1) Create the udev rules file:

as root:

vi /etc/udev/rules.d/50-usb.rules and add one of the following
Allow access by everyone (kinda un-safe)

KERNEL=="ttyUSB[0-9]*",MODE="0666"
KERNEL=="ttyACM[0-9]*",MODE="0666"

Allow access by members of the 'wheel' group-

KERNEL=="ttyUSB[0-9]*",GROUP="wheel",MODE="0660"
KERNEL=="ttyACM[0-9]*",GROUP="wheel",MODE="0660"
