Reply to How to turn a Kontrol F1 OFF?

In my setup I have two Kontrol X1's and a Kontrol F1.
They are all connected to my MBP Retina via a powered Targus USB 2.0/3.0 hub.

When I shut down Traktor the X1's will turn off but the F1 will stay on in a kind of dimmed state.

Any suggestions how to make the F1 turn off all lights when you quit Traktor?

Thanks in advance.
