What to do if you can't get access to the serial port/USB under GNU/Linux?

Translations: DE, SV

If the access rights to device files (serial ports, USB) are not set appropriately under GNU/Linux, the user can neither program a microcontroller nor use the mining software 'AVR_Miner.py'.

If you want to program an Arduino UNO with the Arduino IDE for the first time, you will almost always run into the problem under GNU/Linux that the IDE does not have access to the serial port (i.e. USB) and thus cannot find the microcontroller. The solution: Correct group membership (and not release device files for all/everyone as often described!).
