Vista usbport.sys 500hz mouse polling rate.

[Jim]

Thought i'd share this file with you guys as it's taken me ages to hex edit, and it may come in handy for anyone who is planning on gaming on Vista.

These files will increase your USB polling frequency from the Windows Vista default of 125hz to 500hz or 1000hz making your mouse much more responsive in gaming.

This file will only work on the RTM/Final version of Vista 32-Bit and 64-bit. If you want the same hack under Windows XP just search google for "XP usbport.sys 500hz".

How to install

1. Restart Vista and repeatedly press F8 to bring up the boot menu. Select 'Safe Mode'.
2. Run the following command from the Run box: bcdedit -set loadoptions DDISABLE_INTEGRITY_CHECKS
3. Run the following command from the Run box: takeown /f "C:\Windows\System32\Drivers\usbport.sys"
4. Run the following command from the Run box: cacls "C:\Windows\System32\Drivers\usbport.sys" /G username:F
(replace username with your username)
5. Open C:\Windows\System32\Drivers and locate the existing usbport.sys
6. Rename usbport.sys to usbport.old
7. Copy the usbport.sys in the file below (which corresponds with your vista version and desired usb frequency).
8. Restart Windows
9. Run mouserate.exe to verify that you now have a 500/1000hz polling rate.

Ok, here are some commands which make it easier to take control of the file.

takeown /f "C:\Windows\System32\Drivers\usbport.sys"
cacls "C:\Windows\System32\Drivers\usbport.sys" /G username:F

Much easier .

You nerd

Nice work though, will be using it when i install my copy of vista

[equk]

cool

similar to the hexedit for windows xp

altho with xp there are different versions of the usbport.sys file. So you need to go carefull.
I guess atm Vista only has 1 version.

Does vista keep backups in driver.cab etc tho like XP, so it can restore the original if it has changed??

It doesn't seem to as I only replaced the one version. If you search the filesystem there is another copy of it nested away, but it wouldn't let me overwrite it no matter what :s

You got G5 drivers installed? Some change the polling rate automatically.
