How to Increase USB Sample Rate in Windows Vista/7

**Regeneration** · December 2nd, 2008, 10:45 AM

The default 125Hz USB sample rate in Windows Vista and Windows 7 is not enough for today’s gamers and end-users. There are many USB sample rate patches out there, but none of them support Windows Vista and Windows 7, due to a new restricted driver signature enforcement feature. Now it is possible to use these patches - thanks to the latest version of our own Driver Signature Enforcement Overrider (DSEO) and SweetLow. These patches and our tool have been well tested, but I am not taking responsibility for any damages! Use it at your own risk.

1. Download Driver Signature Enforcement Overrider from this link.
2. Download HIDUSBF (attached below as hidusbf.zip).
3. Run Driver Signature Enforcement Overrider and choose Enable Test Mode.
4. Extract HIDUSBF to some folder, right click on HIDUSBF.inf and choose Install.
5. Run Setup.exe from HIDUSBF’s folder, check the Filter on Device box and select your desired sample rate.
6. Run Driver Signature Enforcement Overrider again, choose Sign a System file and insert full path to the installed HIDUSBF.sys file (For example: C:\Windows\System32\Drivers\HIDUSBF.sys).
7. Restart your computer and enjoy.
8. Verify by using Mouse Rate or DirectInput Mouse Rate (attached below as mouserate.exe and dimr.exe)
9. If you would like to remove the test mode watermark, run Driver Signature Enforcement Overrider and choose Watermark removal.

That should do the trick. Remember! Use it at your own risk! Don't blame me if your motherboard explodes. But... I already tested it myself - with a lot of success, so you don't have any reason to worry about . If you would like to uninstall it, just right click on HIDUSBFU.inf, choose Install and disable test mode from Driver Signature Enforcement Overrider.

Thank you Regen - been waiting for this to come up for Vista SP1

Will test it on VISTA SP2 pre-Beta and let you know if it works ok.

Microsoft Windows Vista's 125Hz USB sample rate is plenty. Get a good mouse and get some PRACTICE instead.

Every hardcore gamer will FEEL the difference.
You think that MX518 is a bad mouse ? Because I don't and like it much better that the Razor's products.

When you're used to 1000Hz (1ms), you can't use 125Hz (8ms) and its not just for gaming. But 500Hz (2ms) should be enough.

Thanks for this, thought I was doomed after jumping to vista 64-bit. Anyway, it seems I cannot disable this Safe Mode without losing the shit. Does it affect anything to have this safe mode on 24/7? + the safe mode texts in the corners are annoying.

It's not safe mode, its test mode. It doesn't affect anything and there is a way removing the watermark.. but I can't provide it due to legal issues.

It would be nice if the author also reminds everybody that some mice will not go beyond 125Hz even with this patch. It has to do either with the sampling rate of the frequency the use to transmit with the receiver, and even others such as the MX400 (corded) has limitations due to the sampling chip that it uses to function the laser detector.
Often, corded and optical (NOT laser) are much better suited for forcing a higher refresh rate.

I got sidewinder mouse which have 1000hz polling rate.. But I am getting 490-520ms.. My os is vista 64.
I tried many fixes but nothing effecting.. How to solve it?

The maximum USB sample rate on Microsoft's SideWinder is 500Hz. But that's a lot better then 125Hz.
