Symptoms

The Battle.Net launcher detects my Bluetooth PS4 controller (I can use it in the launcher's UI), but Diablo IV doesn't recognise it - the only workaround I've found besides SteamInput is to disable Hidraw using the registry (HKLM\System\CurrentControlSet\Services\winebus, DWORD "DisableHidraw"=1). Using this workaround enables the game to detect my controller, but it detects as an Xbox controller, which gives me the wrong glyphs in-game. However, the controller works normally and gets detected as PS4 if it's connected via USB.

Reproduction

1. Connect PS4 controller via bluetooth
2. Install Battle.Net as a Non-Steam game
3. Change the Steam executable to the newly installed Battle.Net location
4. Open Battle.Net and install Diablo IV if necessary
5. Confirm: controller is working in the launcher
6. Launch Diablo IV
7. Controller doesn't work in-game
