Hi guys, Sorry for the late response. I read what everyone was posting and here is what I found out. Even tho I used a separate USB port thinking that it may be the problem, it still didn’t recognize EAC RDR/ALTM and PATH buttons on the throttle. SO… I tried ANOTHER USB port. A 3.0 Port and lo and behold, the lower buttons now work.
With that said, I am now trying to figure out the best way of mapping. Right now I have:
7-8 = Increase / Decrease Flaps.
9-10 = Gear Up & Gear Down
Slider 20 on right side of throttles = Spoiler Axis.
Parking Brake = 20
Mixture = Slider X
Some of the suggestions here are great and I will keep assigning and report back here. Thanks to all.
