Hello!!

Just bought a new computer and everything works just fine, exept that dont know how to install 500hz USB mouse. Is there any easy installers out there? I found one guide, but i have fucked up 3 ports already=)

http://www.ngohq.com/news/15043-how-to-increase-usb-sample-rate-in-windows-vista-7-a.html im folloing this guide, but dont get it to work without ruin my usb ports...

Thank you in advance.

usb standards mandate 1000hz support on the host. it might fry the mouse, but if it damages the host then your computer hardware really sucks.
try uninstalling buggy drivers, or reboot to fix those 3 ports.
regarding win7 drivers and overriding the device descriptor's requested poll rate - I have no idea.

So you have Windows 7? That is the right guide. Just follow it step by step: Run test mode, right click HIDUSBF.inf and install, run setup.exe, click filter and choose 500hz. then copypaste C:\Windows\System32\Drivers\HIDUSBF.sys into told program and restart. Should work....

You can access newest version at this link:

Read the readme, it also mentions Vista (so I assume it should work on win7 as well).

Got it to work..

But i want my USB ports to work again, is that possible??

Got it to work, uninstalled the usb ports, and rebooted.. it started to work again...!!
