Please describe your issue in as much detail as possible:

When I try to wake my computer from sleep with a Bluetooth Gamepad (8BitDo Pro 3 in Dinput Mode) it does not work.

Steps for reproducing this issue:

1. Install SteamOS on a computer that has an MSI B850M-A WIFI
2. Update to the latest stable version 20260716.1 and pair Bluetooth gamepad to it.
3. Turn on the controller and let it try to connect

Extra context: This gamepad (8BitDo Pro 3) is able to wake my Steam Deck OLED without issue so I am unsure why the same does not apply for my computer
