+Display the current mouse refresh rate under linux with evdev
-It is sufficient to simply download evhz.c vs cloning the repo.
+For information about polling rate, see https://wiki.archlinux.org/index.php/Mouse_Polling_Rate
-To compile and run:
+Just do ./run (run is very short and readable).
-gcc -o evhz evhz.c
+Nonverbose mode = -n, but you probably don't want that.
-sudo ./evhz -v
+Reported average is for the last 64 samples, or as many as we have so far.
-Bugs, patches, requests, etc. are welcome.
+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.
