I've always had issues when I attempt to connect to serialports on Ubuntu. I can temporary get by when I execute: sudo chown :rich /dev/ttyACM0
However, that gets annoying when I have to resubmit that command in the terminal. I tried to add the user rich to the dialout group, logout and log back into my account; however, I still get the Connection error when I attempt to connect to /dev/ttyACM0 How can I get the Espruino chrome app to gain access to /dev/ttyACM0 without having to execute the chown command?
