Unable to connect Arduino Uno to Ubuntu 16.04 I've received an Arduino Uno today only. I have zero experience prior to Arduino boards or any other micro controller. I followed every step very carefully from the setting up guide for Linux based OS, but I still can't connect the board with my Ubuntu 16.04 PC. After googling the problem I found that the device must show up as ttyACM* but I don't see any such device in /dev. Its also not listed under the command lsusb but the LED's on the board are working properly. The ON LED is turned on when I connect it with my PC and the inbuilt LED starts to blink.

This is what the IDE displays:
You may have to add yourself to the dialout group in Ubuntu so that your user account can access the serial ports.

Then, in the Arduino IDE, the Tools->Port menu should show you options. Right now, the screenshot you gave shows that it's set for COM1, which is a Windows-style serial port naming and definitely won't work on Ubuntu.
