Just plugged in the masterkeys Lite L and no rgb or back lighting at all. Only lighting I have is the N C S G in the top right corner, the G. Tried plugging keyboard into multiple usb ports but nothing happens no RGB at all. Also tried resetting using the FN + right alt then FN+E and nothing again. FN+F1 through to F12 does nothing also. Really disappointing as you can not read the keys at all with no light.
