If you can run Lightburn from root and connect, this should fix it.
Unless you’re in the root group, the permissions are read only and your software has to write to the controller.
This is likely hardware dependent, so if you change usb ports it could change the usb bus:device.
I changed mine by changing the others (o=rw) to read/write.
$ls -l /dev/bus/usb/001/010
crw-rw-r-- 1 root root 189, 9 Jan 3 16:05 /dev/bus/usb/001/010$sudo chmod o=rw /dev/bus/usb/001/010
If you run Linux, Lightburn is no longer supported on that platform, so if you find newer control boards, it might be they are only supported with Lightburn versions 2.0 and higher.
I didn’t need to load a driver, if you see the device with lsusb, then driver is likely OK. With Linux, most of the drivers are there, but may not be installed.
