Are you playing in VR? No
Which part of the game is the issue happening in? Other
Please explain 'Other' All flight modes
What were you doing when the bug occurred? Step by Step detail is helpful. Attempting to get the game to register the YAW axis input coming from the MFG Crosswind rudder pedals
Where did this issue occur? Please include menu name or in game location. Remap Controls menu, flight stick section
When did this happen? (dd.mm.yy hh:mm) 09.10.20
How often does the bug occur? Every time (100%)
How severe is your issue? Can play, but it's highly frustrating
What happens when the bug occurs? The game will not recognise the input from the rudder pedals even though the pedals are correctly identified in the controls menu (scroll to the very bottom for list of input device). The best I have managed is to get the game to register a *single* axis direction on the pedals (eg I can yaw right, but not left).
What do you expect to see? I expect to see YAW right on the +Z axis and YAW left on the -Z axis
Which ship were you playing? If not applicable, just answer "no" or "none." no
What components were you using? Warthog Joystick Warthog Throttle MFG Crosswind rudder
Which customizations (if any) were you using? None

Systematic problem getting game to correctly register rudder pedals as a valid input device.

 I have the following case:

Thrustmaster Warthog joystick.

Thrustmaster Warthog throttle.

MFG Crosswind rudder pedals.

USB mouse + keyboard.

When I have all those devices plugged in the behaviour in-game is:

Joystick axis and buttons all register in-game and can be assigned actions.

Throttle axis and buttons all register in-game and can be assigned actions.

Rudder pedals only register in a single direction (ie I can assign 'yaw right', but when I try to assign 'yaw left' to the opposite rudder motion the game does not register any input)

Mouse pointer is not visible or useable on screen unless I hold down the right mouse button continuously.

If I remove the Warthog throttle and stick and just have the pedals, mouse and keyboard attached:

Rudder pedals recognised and I can assign yaw direction without problems on the + and - rudder axis (and pedal action as well).

Mouse pointer fully visible and works nominally

Switching out the Warthog HOTAS + MFG Crosswind pedals and replacing it with the standard plastic Thrusmaster HOTAS (with twist on joystick for yaw):

All joystick and throttle axis are recognised and can be assigned

Mouse works nominally

Sadly the plastic joystick is nearing the end of it's life, is very spongy and not that precise - I would really like to be able to use the Warthog/rudder combo that I use without problem in *literally* every other flying-style game that I own.  Right now if I want to switch game I have to unplug/replug a bunch of stuff before I start.
