LightBurn cannot find my laser

I have tried USB and ethernet connections with no luck. I have read forum after forum and nothing seems to work. Laser is model 350 with 50w laser. My pc recognizes the USB connection but that’s it. My ethernet is plugged into a switch box and there is no connection at all. I am at a loss. :weary:

I had to reload LightBurn and check the little box to load the drivers.
