Arduino IDE on Pop OS 21.04

I have tried following the installation from https://www.arduino.cc/en/Guide/Linux

However, I get the following error when I run ls -l /dev/ttyACM*
ls: cannot access '/dev/ttyACM*': No such file or directory

It is the same result for ls -l /dev/ttyUSB*

The command sudo usermod -a -G dialout executed without error.

Due to this Tools -> Port option is disabled.

What do lsusb and dmesg say when you connect the board?

output of dmesg

After a while the WinChipHead device (arduino device) disappears

Forgot to ask, which board?

If the board disappears, there might be something wrong with the board. I doubt I can help you further.

It is uno r3. Let me check with another board.

You are absolutely correct. The board was faulty. Thank you.
