Connecting a FRDM-KL46Z to Ubuntu 18.04.1 LTS

17 Sep 2018

I have updated the board, and Linux recognizes it as MBED. When I search for the board with /dev/ttyACM* the terminal reads bash: /dev/ttyACM0: permission denied

I have tried quite a few fixes that I found through google. i have added myself to the dial out group using sudo chmod a+rw /dev/ttyACM0 sudo usermod -a -G dialout USERNAME

after logging out and back in ls -l /dev/ttyACM* returns crw-rw-rw- 1 root dialout 166, 0 sep 16 16:30 /dev/ttyACM0

I have added a rules file (contents on next line) to etc/udev/rules.d SUBSYSTEMS=="usb-serial", TAG+="uaccess"

I have also tried /dev/ttyACM* as the super user, and it returns the permission denied message.

Can anyone shed light on what is happening, or what I can try?
