I bought Arduino Mega board (CH341 usb) and I am able to connect to /dev/ttyUSB0 (upload to device) only by using sudo.
OS: Ubuntu 18.04
What I've tried:
I have downloaded Arduino IDE and added my user to dialout group. Logged out and logged in. Still nothing.
Installed Arduino by using apt
Installed Arduino by using snap
For all three cases it worked only by running as root (sudo actually). I saw couple of answers for Ubuntu 14.04 but none of answers didn't help.
I guess some other device access permissions are missing but I still didn't find any solution.
