This significantly reduces cpu usage. On my laptop before this change a
single core would be fully loaded while running at 3-4GHz. With this
change it would only be loaded for about 50% while running at 1-2GHz.
This improves battery lifetime while also preventing the fan from
spinning up to a distracting level.
This shouldn't noticably affect latency given that most keyboards and
mice don't support polling at 500Hz anyway.
