I have the UDOO x86 Ultra (1st gen) with the Intel Aduino 101 on board running Ubuntu 18.04. If run 'ls /dev/tty*', then will the Arduino 101 be listed as ttyUSB0 or something else?
@waltervl, thank for checking. In my case, I'm not able to see the /dev/ttyACM0 listed. I do see /dev/ttyUSB0 if I connect an external Arduino Uno board using the USB connectors and cable though.
