Having a HOTAS throttle and/or a rudder pedals connected to your computer presents with serious issues in ARMA Reforger. Reforger automatically remaps those controllers to existing bindings and makes controlling vehicles (possibly more) in game nearly difficult to impossible until those controllers are removed.
I've read others have seen issues in other parts of the game (Game Master for example) when such controllers are present.
Once these controllers are disabled in Windows or physically disconnected the issue will go away and standard input works.
Note: I have mostly run into this with vehicles. I have not noticed issues related to the fact that my “standard” Joystick (a Thrustmaster T1600.M) is plugged
I use these additional controllers for ARMA, DCS, and Flight Simulator so having to disable/disconnect those every time I play Reforger is extremely annoying. Especially doing so physically since I've incorporated my HOTAS Throttle into my cable management which makes physical disconnection very difficult given the connection is under my desk.
This needs to be fixed.
On my PC specifically I have:
MFG Crosswind V3 Rudder Pedals
Thrustmaster T1600.M Joystick
Thrustmaster TWCS Throttle controller (part of HOTAS)
--Finally, Windows recognizes my Razer Huntsman V2 Analog as a controller because it's optical switches can be used to emulate one. That being said, I’ve replicated all these issues using a standard keyboard so the V2 Analog has no impact that I can ascertain at this time.
