I have just received my Pro Flight Yoke System today. I installed it and my Rudder Pedals as per instructions on my new computer and had a successful first flight in X-Plane 11.
After my computer was asleep for an hour or so, I decided to have another flight. I also decided to change my USB ports to two more convenient ones.
The rudder pedals were fine, but the Yoke was no longer recognised. I've tried uninstalling and reinstalling the drivers, but getting the same results described above by rpmacks.
Curiously, I plugged the Yoke into my iMac and it was recognised straight away.
The Yoke plugged into my PC does not turn on, so I don't see how I can configure it in x-plane 11 when the computer does not recognise it's existence any more.
