I'd like to say that I'm a noob at both Arduino & Ubuntu (have some command line experience).
I've set port permissions, joined the relevant groups (tty,uucp,dialout & plugdev). I know that the IDE recognizes the board because ttyACM0 only shows up when the board is plugged in. I've searched the Internet and Stack Exchange and Arduino troubleshooting guide and tried all the suggestions. It's not Genuino but a knock-off that's recognized as an Uno. I've got to be missing something.
Are there any relevant logs or a way to monitor whats going on in realtime?
