The above mentioned videos have no bearing on the issue. They assume that X-Plane is seeing the connected USB Controller. X-plane 11 does not see any USB controller on my system. I should note that X-Plane 9 and X-Plane 10 both are also installed, work well with my desired controller, and X-Plane 11 did work up until a couple of weeks ago with the same exact controller.
So the problem I have is I cannot setup the controller in X-Plane again because it used to be, its because It is as if the controller is not even connected, Even though it is. I do not have the screen in the videos that I used to have that allowed me to configure the controller, I just have the screen that says No Flight controls found. There is no checking the joystick ail/elv/rud because it doesn't seem to exist in X-plane 11 (it is in X-Plane 10).
This is very frustrating that this controller that used to work just fine and I have logged over 30 hours with the controller, doesn't work anymore for this application.
