-If you get permission errors when running any of the commands above, you may need to add your user to the communication group (`dialout` for Debian or `uucp` for Arch Linux), using `sudo usermod -a -G [communication_gruop] $USER` and re-login. Running the commands as `root` is not recommended since this will make `bflb-iot-tool` create root-owned files in your home directory. You can now run `exit` from virtual environment.
+If you get permission errors when running any of the commands above, run `ls -l /dev/tty[DEVICE]`, to find out which group is allowed to talk to serial ports and add your user to that group, with `sudo usermod -a -G [GROUP] $USER` (i.e. `dialout` for Debian or `uucp` for Arch Linux). Make sure you re-login. Running the commands as `root` is not recommended since this will make `bflb-iot-tool` create root-owned files in your home directory.
