[WSA] project crashes when legacy (non-XInput) USB joystick is repeatedly plugged in and unplugged from PC

Windows Store Apps


Legacy (non-XInput) USB joystick can be called, for example, PlayStation 3 controller.

Game build crashes when a legacy (non-XInput) usb joystick is repeatedly plugged in and unplugged. This does not happen when using XInput (Xbox, Xbox One controllers) devices because they use the Gamepad system and not the HidDevice system.

The crash always happens when the device is unplugged. Based on research of the error message, it appears that a HidDevice handle is being used after the device is disconnected.

Exception thrown at 0x74DFDAD8 in blanktest.exe: Microsoft C++ exception: Platform::DisconnectedException ^ at memory location 0x0F55F87C. HRESULT:0x80010108 The object invoked has disconnected from its clients.

WinRT information: The object invoked has disconnected from its clients.
