GameInputEvent.DEVICE_REMOVED doesn't trigger itself

Hi everyone,

I'm trying to detect when my gamepad is deconnected in order to reconnect it later. When I initialize my gamepad, I add listener to GameInputEvent.DEVICE_ADDED, and GameInputEvent.DEVICE_REMOVED. The first one well triggers itselft but only at the beginning, and when I add some others devices it is not trigger again. Moreover event DEVICE_REMOVED, doesn't trigger at all.

if (Game.gameinput == null){

       Game.gameinput = new GameInput();

       gameinput.addEventListener(GameInputEvent.DEVICE_ADDED,onDeviceAdded);

       gameinput.addEventListener(GameInputEvent.DEVICE_REMOVED,onDeviceRemoved);

  }

This function is static, and onDeviceAdded and onDeviceRemoved too.

Do you have some ideas ?

Thanks.
