Fix - "Unsupported" Controller Issues

First off, I use a program for my controller called InputMapper - this forces my PC to recognise my controller as an Xbox 360/One controller. I would recommend using this and setting the controller profile to "default" on the main screen.

To clarify, I'm using a PS4 controller.

Next, in game you must do the following:

• Go to Settings -> Controls
• Use Page Down to navigate to "Wheel" (yes, you read it right - Wheel)
• Press "X" to customise and UNBIND every single key/action - but ONLY for the Wheel
• Save all these settings
•  (Optional) Cross your fingers

Why does this work? Because the "unsupported" controllers are recognised as both a controller and a wheel; therefore, the inputs get mixed up and no matter what you try, something will always get recognised as handbrake.

I really hope this helps, as it's worked wonders for me.
