Project P.I.T.T. Steam Deck External Controller — Safe Checks
Steam Deck External Controller — Safe Checks: Valve's dated compatibility note says external Bluetooth/USB controllers may need manual selection in the Quick Access Menu.
Valve's dated compatibility note says external Bluetooth/USB controllers may need manual selection in the Quick Access Menu. This is more specific than reinstalling the game.
Isolate the failure
Confirm the external controller is connected and selected as the active device before comparing bindings. Keep the built-in controls available so you can undo the selection.

Preserve the useful evidence
Record whether the problem is selection or a particular action. The historical compatibility test does not establish a fresh 1.0.8 benchmark or every third-party controller's mapping.
