Increasing your USB gaming mouse polling rate with USB Mouserate Switcher 1.1 (usbmrs11.exe)

In my last post I talked about how to check your gaming mouse polling rate with a Windows utility called mouserate. You may have noticed that my polling rate was way above the standard 100Hz - in this post I'll tell you how I did it. This obviously only works with USB mice but there are not that many PS/2 gaming mice sold these days.

Important Disclaimer: Although I have not had any problems since running this patch, there have been reports on various gaming forums that people's mice or other USB devices have stopped working as a result of applying this patch. For some people it was fixed by choosing a slower patch rate but I wanted to mention this, as if you follow my instructions below and something goes wrong with your setup - your on your own... (it might be best to have a PS/2 mouse handy or know the keyboard shortcuts to revert the patch).

Ok with that disclaimer out the way, let's get stuck in and really ramp the polling speed up. First download USB Mouserate Switcher 1.1 by Anir. I had problems using the "Softpedia Mirror (US)" link but the "Softpedia Mirror (RO)" one worked fine. When you double-click usbmrs11.exe you are presented with a screen explaining what the tool can do. Clicking the "patch" button moves you to the screens that let you choose what speed you want to try. With each page it asks you if you want to change to that speed. It starts with 250 Hz/4 ms (slow), then 500 Hz/2 ms (medium), and then the fastest setting 1000 Hz/1 ms (the next page asks if you want to revert to the very slow Windows standard of 125Hz/8 ms).

If you answer "yes" to a question it patches the usbport.sys USB driver and asks you to reboot for the change to take effect. When you reboot is when you will find out if the patch has worked or if it has caused some or all of your devices to stop working.

If you have problems with any of your USB devices then try choosing a sightly slower setting first, if that doesn't work you will have to use the tool to restore the original Windows version - remember your USB mouse might not be working at this time, hence the reference to the PS/2 mouse above.

Once you've patched and rebooted, rerun mouserate to see what your new average polling rate is. Please leave me a comment below to let me know if it works (or not), and what average rate you are able to get. Also let me know if you think it makes your aiming and gaming any better.

anir = plagiat

I'm not sure how Anir (who created that program many months ago) could be plagiarising a new program that was released today, but thanks for the update anyway!

anir used RaZiel's usb hack without a permission.

I can see that Anir posted a comment thanking RaZiel for the patch, and I don't see anything that mentions that he made (or was going to make) a utility that uses this hex coding.

I think Anir should give credit where credit is due but I'm not sure if permission should be seeked, it's not as if RaZiel was going to be making big money from this hex hack.

I'm not as informed about this topic as you are but was Anir not just trying to make a utility that was easy to use rather than relying on people hacking their USB drivers with a hex editor?
