Dragonboard can't detect RawGameController

Question

I am making a UWP app that runs on an Arrow Dragonboard. The Dragonboard is running Windows IoT (10.0.17763.1)

I've plugged a USB joystick into the Dragonboard, but Windows doesn't seem to detect it.

var rawInputController = Windows.Gaming.Input.RawGameController.RawGameControllers.FirstOrDefault();
//rawInputController is null

If I run my app on my local machine, and plug the same joystick into my PC, the joystick IS detected.

Is there something that I need to configure on the Dragonboard in order for this to work?

Answer 1

I solved it by modifying the package manifest of my UWP app. I added the following lines to the <Cabailities> node.

<DeviceCapability Name="humaninterfacedevice">
  <Device Id="any">
    <Function Type="usage:0004 *"/>
    <Function Type="usage:0005 *"/>
  </Device>
</DeviceCapability>

This doesn't seem to be a requirement on PC, but it is required for the Dragonboard.
