Show mouse refresh rate under linux + evdev
For information about polling rate, see https://wiki.archlinux.org/index.php/Mouse_Polling_Rate
Just do ./run (run is very short and readable).
Nonverbose mode = -n, but you probably don't want that.
Reported average is for the last 64 samples, or as many as we have so far.
There exists a kernel bug for USB ports which use the uhci_hcd driver, where a 1000 hz mouse will only read at 500hz, causing jittering: https://bugzilla.kernel.org/show_bug.cgi?id=60586. A workaround is to use USB ports that use the ehci-pci driver.
