-evhz
-====
+# evhz
 
-Display the current mouse refresh rate under evdev linux system.
+Show mouse refresh rate under linux + 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
+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.
 
-Bugs, patches, requests, etc. are welcome.

+Last tested 7/2016 on Debian testing. Still working great after several
+years.
