Why does the focus motor have two USB -C ports?
When I plug in one USB -C I get a red/ green flashing light which then stops on red.
I am trying to use it with the focus control in the handle.
I have only plugged in one of the 3 supplied cables ( the other two are camera tether and raveneye power)
How do I power/activate the focus motor?
I have both camera and lens in MF.
Camera is Panasonic S1H.

I had the same issue. How i fixed it was using two cables. No idea how it wirked but I found that it required two usb cables to power the focus motor on my RS3.
