Vista Tutorial - Increasing USB polling rate

I recently learned about the polling rate of USB ports, and how the standard 125hz invariably leads to a 8ms delay with mouse action.

I would like to know how I can increase the rate to 500hz and if it is safe to do this. Unfortunately I use a laptop (Acer Aspire 9520), even for gaming, so it's imperative my USB ports retain their functionality.

As a side note, I found a myriad of instructions on how to do this on XP. None of these work on vista, not according to those who've tried them atleast. (I'm running Vista Home Premium 32bit).

EDIT: I use a USB headset in another port if that makes any difference.

I did find a program that works with Vista a while ago when I had my old mouse, but since I got my Logitech G5 mouse the software with that does it for you, which also works with Vista.

I'll try and find the software I used to use to do it, it worked fine and was easy to do.

It is safe to do it, but you will notice a slight increase in CPU usage, though it wasn't anything to worry about when I did it. It was hardly noticable.

Edit: Found the program http://files.filefront.com/hidusbfzi.../fileinfo.html.

This worked on Vista 32 bit and 64 bit for me, but obviously with 64 bit I had to disabled driver enforcing for it able to edit the usb file.

There's a readme file that includes all the instructions to doing it right, and download mouserate to check your speed to see if it's increase correctly.

This only increases it for your mouse, as well.

I tried this too before i got my G5 , to suppliment Everlongs post here are some instructions

not seen mouserate checker before

im getting 958hz average with my G5 set to 2000dpi and 1000 reports per second!!

Thanks, Archie, that's a nice guide
