Here's where I am right now (and the quad is still not working):
1) I uninstalled the Control Manager
2) Unplugged the device.
3) Reinstalled the Manager
4) Plugged the device into a USB 2.0 connector
5) Launched Control Manager and totally calibrated the device. (Every axis and switch worked)
6) Started FS2020 and went to the controller set-up.
7) Disabled the X-56 throttle controls
8) Programmed the quad, and everything seemed to work, including the switches.
At this point I have to state that while the axes seemed to work, and the switches registered, when I went back to test the switches, although they were showing, they didn't highlight/illuminate when I used them. This included every switch, including the ones in the axis controls.
At this point, I have left the quad connected, but have created an "Empty" profile for it, with no programming. And I'm back to my X-56. So if anyone has a better fix or another way to set this up, please give me a shout. The quad worked perfectly in FSX and DSC, so it's not the device.
