all of of XInput's four device slots. WinRT and XInput do not appear to
have callback-based APIs to notify an app when a device is connected, at

Once a device is connected, calling XInputGetState() is a much less costly
operation, with individual calls costing well under 1 ms, and often under
0.1 ms [on a 1st gen Surface RT].
