Hi Ryan, sorry to hear you are having problems.
You have said you are new to the throttle quadrant (I have it too) so I thought I would mention a few things for you to consider. Some of these might seem a bit elementary so apologies for that but I thought I would mention them anyway.
-
have you calibrated it in Windows?
-
I use the default Windows driver and don’t use any saitek/logitech driver
-
What assignments have you set it up with in FS2020 control settings? I would look carefully at how you have set up the axis and buttons.
-
Do your other controllers use duplicate control settings? If so this could create a conflict.
-
Maybe try it in another PC USB port. It might prefer USB2 or USB3 or even powered. Can’t remember tbh but try switching it anyway to another port.
-
Has it ever worked properly or is this problem just very recently? It’s probably not faulty but I just thought I would throw this in the mix anyway.
-
Try other aircraft. If it works okay with those then maybe the TBM files have been corrupted.
-
Is the throttle stand alone or part of a bundle with the yoke. If the former it is a USB connection. If the latter it should be connected to the yoke.
I don’t fly in the TBM anymore but I can confirm that it is working for me in the PMDG DC6, Milviz Corsair, Stearman, Just Flight Piper Arrow Turbo, Cessna 152.
Hope this might help a little bit anyway.
Cheers
