Was LightBurn able to ‘find’ your device or did you manually set up your device profile? If you set it up manually, what Device Type did you choose?
You may need to install a driver, available here: CH340 Drivers for Windows, Mac and Linux
You may also need to manually select the correct COM port from the drop down menu in your ‘Laser’ window. You’ll see a response in your ‘Console’ window when you’ve selected the correct port.
If you’re still unable to connect, make sure your USB connection is firmly seated, and try a different, higher quality USB. If you’re using any USB hubs or extenders, take them out of line.
Here are some additional resources on connection issues:
