            Bug ID: 45688
           Summary: Gamepad appears both as dinput and xinput (eg.
                    Valkyria Chronicles)
           Product: Wine
           Version: 3.11
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: directx-dinput
          Assignee: wine-bugs at winehq.org
          Reporter: gabriel.corona at enst-bretagne.fr
      Distribution: ---

AFAIU, on Windows a gamepad appears either on DirectInput or on XInput.

Some games are helpful and automatically work with both. For example, Valkyria
Chronicles apparently automatically switches between DirectInput and Xinput
based on the latests input.

On Wine >= 3.3, every gamepad appears both on DirecrInput and XInput. This is
useful because the gamepad can work both on DirectInput and XInput gamed.

However, on Valkyria Chronicles (for example) the effect is that the game
switches randomly between the two modes because it apparently sees the same
gamepad from both APIs. This can be seen because the buttons displayes on
screen change from numbered key labels ("1", "2", "3", etc.) and XInput based
key labels ("A", "B", "C", "D").

In order to sucessfully run the game, I has to disable the gamepad from
DirectInput (using "wine control"). This works, but prevents running
DirectInput only games without reconfiguration.

A possible workaround would be to have an option to disable DirectInput
gamepads if both libraries are mapped in the same process.
