Vixen doesn’t “see” a controller. It just sends data with know knowledge of where it’s going or if it got there. The controller “sees” data coming at it. It has no idea where it’s from.
That controller details box you’re showing only has info in it when you have a controller selected in the controller list above. I can’t tell from the screenshot what, if anything is selected above.
