A successful setup should show tangible results. Here’s how to test:
If the classic tool fails, try USB Polling Rate 1.0.0.4 from GitHub (by lordofkarma). It uses the modern Windows.Devices.HumanInterfaceDevice API and doesn’t require registry hacking.
Setup is a two-stage process: testing the current rate and then adjusting it. Upon first running the executable, the user is presented with a simple window with a large gray box. Moving the mouse rapidly inside this box generates a live readout of the current polling rate in Hertz (Hz). A standard USB mouse will show a stable average of 125 Hz. To adjust this rate, a companion utility like HIDUSBF (USB Mouse Rate Adjuster) is needed. After downloading HIDUSBF, the user must: usb mouse rate adjuster setup download work
Post-reboot, the user reruns the mouserate checker to confirm the new, higher rate (e.g., 500 Hz or 1000 Hz).
The underlying principle revolves around the USB Human Interface Device (HID) protocol. By default, Windows uses a polling interval of 8 milliseconds (125 Hz) for USB mice, as defined in the standard usbport.sys driver. The USB Mouse Rate Adjuster works by modifying the bInterval descriptor in the USB device’s endpoint descriptor. This descriptor tells the host controller how often to request data from the mouse.

When a user applies a 1000 Hz setting, the utility patches the Windows USB stack’s polling interval from 8 ms to 1 ms. However, not all mice support this. The mouse’s internal microcontroller must be capable of generating position data at that rate. If the mouse’s sensor cannot update at 1000 Hz (e.g., a cheap office mouse with a 125 Hz sensor), the adjuster will force the USB host to poll faster, but the mouse will send duplicate or unchanged data, causing erratic movement or stuttering. On compatible gaming mice, the result is a dramatic reduction in input lag—the time between physical movement and on-screen cursor response drops from 8 ms to 1 ms.
USB Mouse Rate Adjuster (often referred to as USB Mouserate Fix or Mouse Rate Checker) is a small utility tool primarily designed for Windows operating systems. Its main purpose is to modify and optimize the polling rate (also called report rate) of a USB mouse. Setup is a two-stage process: testing the current
By default, Windows may limit USB mice to 125 Hz. This tool can unlock higher polling rates, reducing input lag and improving cursor smoothness—crucial for competitive gaming or precision design work.
If you search for a generic "USB Mouse Rate Adjuster" online, you will likely find old, abandoned software from the mid-2000s (often named "HertzChange" or similar hacks).
