Preface:
If you can not underclock even then you can not overclock definitely!
Don't ask help for overclocking here without magic words "I can set a lower rate but not a higher".
And yes, to be 100% sure of the result it's good to know before trying to test NEW device that your SYSTEM allows such kind of overclocking with help of one of the "tested and approved" devices listed below.
Original post:
Testers wanted!
One month before I modified USB overclocking software for work in Win8 - Win10.
First and only fat bug was debugged yesterday
But nothing can stop overclocker. In development process i had seen one feature in code of USB3.0 host controller driver - so it's here: trying to reach polling rates higher than 1000 Hz!
What we need to try?
1. USB3.x host controller
2. Windows 8, 8.1, 10 or 11 and unofficially Vista or 7 (actually we need microsoft driver for USB3.x host controller - USBXHCI.SYS)
3. USB mouse (low/full speed) attached to this controller. Don't mix "controller" and "port" - it's different concepts. You can verify which controller process your mouse in Device Manager, Devices By Connection (device tree) view (qsxcv screenshot from here):
Do not use USB hubs (for first try), it can restrict rate, attach mouse to controller ports directly. In Device Manager mouse (or HID or composite devices) must be attached to "USB Root Hub" as at screenshot above. Some xHCI controllers like this VIA can have built-in/embedded USB hub for low/full/high speed devices so it's not possible to have 2000+ Hz on such hardware. And some non chipset or this Asmedia controllers are just restricted (hardware bug?) in interrupt rate probably. Some AMD chipset xHCI controllers restricted too.
4. Software:
hidusbf.zip - My official package from 2021-04-02
hidusbfn.zip - Addition for some recent versions of Windows (Win10 x64 21H2 checked). Using described below
Edit: High rate driver versions now included in this package (in appropriate folders).
How to install:
1. Install HIDUSBF and try to change rate (simply change). If this is successed then goto 2
2. Take drivers from 2khz-4khz or 4khz-8khz folders and install it (copy to %systemroot%\system32\drivers\ directly or to the folder of hidusbf setup and then install service).
3. Reboot after 2!
4. Run setup.exe, and try to change rate to 31 or 62. Rate=31 actually equal to 2000 Hz, 62 - 4000 Hz for 2khz-4khz version. Rate=31 actually equal to 4000 Hz, 62 - 8000 Hz for 4khz-8khz version. (Don't forget to restart device.)
5. Check the rate (the best is MouseTester, but you can use dimr, mouserate, MouseMovementRecorder or any other software too). If rate is 31(62) then you done something wrong (new driver installation, USB controller type, newer version of USBXHCI.SYS not known to driver). If rate more than 31(62), but not more than 1000 Hz - you mouse is not capable of HARD overclocking.
You can read manual README.2kHz-8kHz.ENG.TXT from jeshuastarr in hidusbf package too.
If you can reach actual rate more than 1000 Hz - post your mouse name here (better with plots from Mousetester).
I will reference good result from this post.
I personally try this already and my best overclockable mouse (a4tech bw-35) reach 1400 Hz average (unstable).
The list of 2K+ overclockable devices.
This is really overclockable Low and Full Speed devices. High Speed devices are capable to 2K+ from design (but can be overclocked too).
HARD result (thanks to qsxcv and mlt04 sensor):
WMO DOES 8000HZ POLLING
...and all mice with mlt04 (Microsoft WMO 1.1, IMO 1.1, IME 3.0, Blue) are hard overclockable, of course.
and other hard result:
Zaunkoenig M1K (@Windows 7)
This mouse expressly made with hard overclocking in mind
Other good results:
Sky Digital Nmouse 4K
SteelSeries Kinzu v1
Zalman ZM-M600R (same as Nmouse 4K)
Microsoft Basic Optical Mouse v2.0
Roccat Kone Pure Ultra
Logitech M90
Roccat Burst Pro
Dell CN-09RRC7
Satisfactory results:
Razer DeathAdder (v1)
Microsoft Pro IntelliMouse
And other not so good result:
Asus ROG Gladius fake 2000 Hz
(and it is NOT possible to get more than 1000Hz on ANY Low or Full Speed device without host overclocking).
P.S. Under modern versions of Windows 10 or 11 (whether you want hard or ordinary overclocking):
1. If you have problem with driver loading on version x64 1607+ disable Secure Boot or modify the Registry accordingly.
2. If you have EHCI (USB2.0) Controller only on version x64 1703+ or any controller on version 1803+ use these drivers and Test Mode or atsiv method or umap method with non Test Mode. If you use atsiv then check your AV (or something else like anti-cheat engine) in case you are unable to load atsiv. Or use atsiv and then unload it completely before loading of such engine. And yes, try not to make that mistake.
P.P.S. If you came here for ordinary (1000 Hz-) overclocking drivers and have Windows 7 (or previous version):
1. For modern PCs with xHCI controller only with Windows 7 or Vista check these unofficial drivers.
2. On Intel chipsets with both EHCI and xHCI controllers (i.e. series 7x-9x) read this manual with this optional addition in case you can not overclock your mouse but still want to use xHCI controller.
Or you can use hidusbfn.zip and one of the two methods described above especially if you have modern Intel hardware with xHCI controller only, but in this case the best solution is 1.
3. VIA USB 3.0 xHCI controllers allow flawless (without its driver patching) overclocking of [Low Speed] devices up to 1KHz under Windows 7 (and XP and Vista probably). But you can try to use 1. too.
P.P.P.S. JFYI (and for problem troubleshooting): There and following the links you will find the little descriptions of hidusbf internals and there - what it exactly does in system.
P.P.P.P.S. The latest checked system files. If you have files newer than these and can not overclock feel free to send them to me.
If you can not underclock even then you can not overclock definitely!

P.P.P.P.S. The latest checked system files. If you have files newer than these and can not overclock feel free to send them to me.
First (and main) - if you can not downclock then YOU do something wrong. Without exceptions. And no matter how your files are new.
Second - if you try to overclock device just in the same USB speed interval (for example Full Speed Device from 500 to 1000Hz) then this table is useless for you. There is no problem in software in this case, only hardware.
Third - usually i'm supporting release versions only and highly unlikely will pay attention on versions with any other readiness. But you can try to ask...
How to use the table.
1. Find your OS.
2. Find USB controller that controls your device. Use "Copy IDs" in Setup:
or Device Manager if something is wrong with "Copy IDs":
![]()
3. Find Driver File name (as above).
You will find two (or even more) driver files in some cases, first is one of USBEHCI.SYS, USBUHCI.SYS or USBOHCI.SYS and second is USBPORT.SYS.
It's normal, we need the second, USBPORT.SYS.
4. Find Driver File version (use "Copy IDs" or Explorer to view property of file):
![]()
Then search in table by OS, File Name, and File Version.
If your file is newer than the latest version in the table then send it to me.
Column "HIDUSBFN needed"=Yes means that you have to take files from addition to main package and use Test Mode or atsiv on x64 OSes.
Column "Possible overclocking" describes what kind of overclocking you can have on this hardware and software combination.
LS=Low Speed (max 125 hz), BusSpeed: 0 (in Setup->"Copy IDs")
FS=Full Speed (max 1000 hz), BusSpeed: 1
HS=High Speed (max 8000 hz), BusSpeed: 2
For example on the screenshots I have Windows 10 x64 1903 (with some update), xHCI host controller, usbxhci.sys Driver File and its version is 10.0.18362.207.
In the table this row is present (10.0.18362.207 falls into 10.0.17134.1-10.0.19041.xxxx interval) and you have to use HIDUSBFN and can potentially overclock your device up to 8000 Hz.
Second - if you try to overclock device just in the same USB speed interval (for example Full Speed Device from 500 to 1000Hz) then this table is useless for you. There is no problem in software in this case, only hardware.
Third - usually i'm supporting release versions only and highly unlikely will pay attention on versions with any other readiness. But you can try to ask...
How to use the table.
1. Find your OS.
2. Find USB controller that controls your device. Use "Copy IDs" in Setup:
Code:
Device:
"USB\VID_046D&PID_C03E\6&265D47D&0&3" <- (first line). This is unique internal name (ID) of device. Use it to restart this device only.

Version: 6.1.7601.24138 (win7sp1_ldr.180502-0600)
Binary: USBPORT.SYS
Path: C:\Windows\System32\DRIVERS\USBPORT.SYS <- This is Controller Driver File
Version: 6.1.7601.24138 (win7sp1_ldr.180502-0600) <- This is Controller Driver File version
3. Find Driver File name (as above).
You will find two (or even more) driver files in some cases, first is one of USBEHCI.SYS, USBUHCI.SYS or USBOHCI.SYS and second is USBPORT.SYS.
It's normal, we need the second, USBPORT.SYS.
4. Find Driver File version (use "Copy IDs" or Explorer to view property of file):
Then search in table by OS, File Name, and File Version.
If your file is newer than the latest version in the table then send it to me.
Column "HIDUSBFN needed"=Yes means that you have to take files from addition to main package and use Test Mode or atsiv on x64 OSes.
Column "Possible overclocking" describes what kind of overclocking you can have on this hardware and software combination.
LS=Low Speed (max 125 hz), BusSpeed: 0 (in Setup->"Copy IDs")
FS=Full Speed (max 1000 hz), BusSpeed: 1
HS=High Speed (max 8000 hz), BusSpeed: 2
For example on the screenshots I have Windows 10 x64 1903 (with some update), xHCI host controller, usbxhci.sys Driver File and its version is 10.0.18362.207.
In the table this row is present (10.0.18362.207 falls into 10.0.17134.1-10.0.19041.xxxx interval) and you have to use HIDUSBFN and can potentially overclock your device up to 8000 Hz.
