So I got myself a wmo recently and tried to change the mouse rate from the default 125Hz to 500Hz. Though I could not seem to get it working.
I used this tutorial: http://www.youtube.com/watch?v=C1bMYV4OI08 (hidusbf, driver signature enforcement overrider, mouserate.exe)
I follow the instructions but the rate is still suck at 125Hz after I reboot.

What I do:
- enable test mode in dseo
- install the hidusbf thingie
- run the hidusbf setup as admin
- change the mouse rate of the wmo to 500Hz and close the setup
- sign the two system files
- close dseo
- reboot
- sadface

My predictions:
- my anti-virus tool is fucking up the dse overrider
- I got the mouse connected to my PC with a USB extension cable (does that cause problems?)
- shit just doesnt work anymore

Any help, please?

Edit: OS is win7 sp1
