$ sudo cat /etc/udev/rules.d/70-lilygo.rules
SUBSYSTEM=="tty", GROUP="plugdev". MODE="0660"
SUBSYSTEMS=="usb", ATTRS{idProduct}=="55d4", ATTRS{idVendor}=="1a86", SYMLINK+="lilygo"Then reload the rules as follow:
sudo udevadm control --reload-rules && sudo service udev restart && sudo udevadm triggerUn-plug your Lilygo then plug it back, the device should be accessible on /dev/lilygo
