Hey guys, as the topic states i need some help with my USB polling rate. I am running Windows 7 SP 1 64bit with a cheap Logitech RX250 mouse and want to have it on 500hz.
I have tried every tutorial that comes up with google and nothing works. I am stuck at 125hz.
I tried http://www.mybenni.de/blog/windows-7vista-und-500hz/ and http://www.ngohq.com/news/15043-how-to-increase-usb-sample-rate-in-windows-vista-7-a.html and like every variation of those.
And i really did it correctly! I am no tech newbie so i doublechecked everything in there.
Is there any other way? Maybe some manual registry-editing or something? I am open for everything!
Thanks in advance!
PS: (please dont start a discussion on the usefulness of higher USB hz rates...)

Interesting! You have the exact same mouse as me... I am also interested in this and I would really like to know if there's a way to increase it.

You could try it the old school way and turn driver signing off?
|
Took me a long time to figure out how to use the driver signing to enable it. Don't give up

I turned it off via the console. Didnt fix it either. Or is there a different followup after disabling it?

It will probably not make a noticeable difference to you, especially seeing as it has a ridiculously low DPI.

I spent a LONG time trying to get this to work and I am trying to remember where i got all the files for it.
In order to adjust the USB polling rate of Windows 7 you need to put Win7 in test mode. This will remove driver signing for the moment.
Alternately you can also download a developer kit and sign your own drivers.
To put Win7 in test mode. Use something called dseo13b.exe

At the bottom right of your desktop a watermark should appear letting you know that you did it correctly.
It is there FOREVER unless you remove the watermark via another application altogether.
EDIT: I forgot to mention, after doing this but before you sign the drivers, you must use the setup.exe included in the folder and set the polling rate of the device to 1khz. THEN you can sign the drivers.
Then you can install the custom drivers. Which I think you possess.
You MUST use the correct drivers, usually you can find this driver in the AMD64 folder in the drivers you downloaded.

Dont worry about the fact that it is called AMD64, even if you are using an intel system.
Finally, reboot, and use MouseMovementRecorder to ascertain your polling rate:

Polling Rate and DPI are unrelated.
Win XP users have the advantage here because XP users can simply use a 10k executable or whatever and set the polling rate right there.
Personally, every modern motherboard should be polling at 1k now. Its ridiculous that we have to deal with low polling rates we cant raise easily.

1k is far from ridiculously low, and if one is concerned about mouse accuracy or input lag, they probably wont be using much higher even if they had the option to.

I use about 800 DPI and thats great for 1680*1050
People use DPI like some sort of mouse benchmark.
They will crank up there DPI to max because they think its cool, then drop the windows sensitivity to compensate. When you want to do the opposite. If you are going to be doing this you might as well be using some 5 dollar shit mouse from Job Lot.
Keep windows at default and change the DPI to whatever suits your needs.
These like 5k DPI or CPI mice are freaking pointless.

Following this
http://www.hardwarecanucks.com/forum/peripherals/24689-changing-usb-polling-rate-1000hz-lower.html
worked for me on my old mouse.
Also, I was randomly spamming keys to get my computer to boot in safe mode, as I didn't know whether it was F8 while starting or F12 or whatever. Anyway, I basically spammed F1-F12 while it started, it brought me to a screen I'd never seen before, where I could do things like boot in safe mode bla bla bla etc. And one option there was to allowed unsigned drivers to load. I apologise as this is very vague and probably won't be the same for your mobo but it's worth a try I spose.

Thank you all for your suggestions.
But unfortunately those are just variations of the ones i already tried. It doesnt work that way. There has to be something that kinda prevents my system to accept it

If you are using 64bit iirc you have to manually move hidusbf.sys to /syswow64 which most tutorials fail to mention, as by default it installs to /sys32.

I did this and signed the file there aswell...

Iono whether it may be worth double checking, but how are you measuring your refresh rate? Could it be possible that it has changed but not being reflected?
|
I used 2 tools: One was called DIMR.exe and the other one was mouserate. Both exactly meassured the limit at 125Hz.
|
My bad, didn't realise it went up to 1k. Seeing the lack of specs on the page I made assumptions I shouldn't have.
I play at either 1200 or 2k dpi, at 6/11 with 1kHz, just looked like it was some shitty optical 400 dpi or something

Try signing the USBHIDF.sys file before (and after too I suppose, just to be sure) installing it. I had this same problem and that is what managed to fix it.

Not gonna lie.
First time i tried getting it to work it failed.
After that I just went all cowboy on it, spamming the AMD64 sys file at every step of the process and eventually it worked after a reboot.
Make sure you are setting the mouse to 1k in setup.exe, I think it writes the driver when you exit. THEN sign the driver you just wrote.
