1. Drivers

   GNU/Linux computers usually have all of the necessary drivers already installed, but users need the appropriate permissions to open the device and communicate with it.

   Udev is the GNU/Linux subsystem that detects when things are plugged into your computer.

   Udev may be used to detect when a device is plugged into the computer and automatically give permission to open that device.

   If you plug a sensor into your computer and attempt to open it and get an error such as: "FATAL: cannot open /dev/ttyACM0: Permission denied", then you need to install udev rules to give permission to open that device.

   Udev rules may be downloaded as a file and placed in the appropriate directory using these instructions:

   99-platformio-udev.rules

2. Download rules into the correct directory

   curl -fsSL https://raw.githubusercontent.com/platformio/platformio-core/master/scripts/99-platformio-udev.rules | sudo tee /etc/udev/rules.d/99-platformio-udev.rules
   

3. Restart udev management tool

   sudo service udev restart
   

4. Ubuntu/Debian users may need to add own “username” to the “dialout” group

   sudo usermod -a -G dialout $USER
   sudo usermod -a -G plugdev $USER
   

5. After setting up rules and groups

   You will need to log out and log back in again (or reboot) for the user group changes to take effect.

   After this file is installed, physically unplug and reconnect your board.
