The core pointer is comprised of merging the inputs of all mice. If there are other mice, they should show up in the device list, and we want to report events from those devices instead of the core events. However, if XInput isn't supported or we can't find other mice in the device list, we'll add the core pointer and interpret normal mouse events.
