Hi :tentacle:

Is the backlight controlled by software or is there a dial/button on the cable or the plug?

It does not have aany external buttons or dials, my previous low quality endoscope had this but new one does not, but it has 4 LEDs, so it must be software control.

Also tried connecting to Windows PC, everything works but no LED control
