I installed a USB Throttle Quadrant to go with my Saitek Pro Yoke/Throttle for twin engine aircraft. The USB Throttle is activating the "G" key and "S" key when I move two of the levers all the way down. The USB throttle system works number two engine prop, number 1 engine mixture, number 2 engine mixture. Num 1 eng mix trips the "G" landing gear key and num 2 eng mix trips "S" view key. What can I do to fix.
