JCZFiber found only when running sudo

It didn’t occur to me that this laser may not connect through a serial connection. In that case it wouldn’t be associated to a TTY device.

Review this post and attempt to apply the fix listed:

Fiber laser installation on Linux

Ok, I should have a solution for you: Run sudo gedit /etc/udev/rules.d/usb.rules (you can also use nano, vi, whatever) Enter the following contents SUBSYSTEM=="usb", MODE="0666" Save the file and close. Then run: udevadm control --reload-rules Now plug your galvo USB connection back into the machine. Run LightBurn without sudo and you should be able to automatically find and connect to the device.
