Improvements and fixes

If your USB device does not work the most likely problem is missing or outdated drivers. When you plug the device into your USB, Windows will look for the associated driver, if it cannot find this driver then you will be prompted to insert the driver disc that came with your device. Short description. This driver/program is intended to 'overclock' USB mice (and other devices) under Windows 98, 98SE, ME, 2000, XP, Vista, 7, 8, 8.1, 10 including x64 versions. Also may be used for downclocking (and downclocking shall work always). When you connect a USB audio device to a Windows 10 Version 1703-based computer the first time, the operating system detects the device but loads the standard USB audio 2.0 driver (usbaudio2.sys) instead of the specific device driver. The small microprocessor on the motherboard will reload the drivers and your USB ports should hopefully be recognizing devices again. So first turn off your computer using the Shut Down option in Windows or pressing the power button and then UNPLUG the PC from the wall outlet. Let it sit for several minutes and then plug it back in.

This update includes a fix for an incorrect device driver (“Microsoft – WPD – 2/22/2016 12:00:00 AM - 5.2.5326.4762”) that was released by a third-party on March 8, 2017 that affected a small group of users with USB connected phones or other media devices that rely on Media Transfer Protocol (MTP). If the driver is on your system, when any of these devices are connected, Windows will try to install this driver. These devices will not be connected until the driver is removed. This incorrect driver was removed from Windows Update the same day, but it may have been downloaded to your computer. After installing this update the incorrect driver will be removed.

How to get this update

This update will be downloaded and installed automatically from Windows Update. To get the stand-alone package for this update, go to the Microsoft Update Catalog website.

If you are not able to connect your phone or media device via USB and are not running one of these Windows versions, you can still remove this driver using the process described here:

Registry settings for configuring USB driver stack behavior

The registry entries described in this topic are found under this key:

In the vvvvpppprrrrr key,

  • vvvv is a 4-digit hexadecimal number that identifies the vendor
  • pppp is a 4-digit hexadecimal number that identifies the product
  • rrrr is a 4-digit hexadecimal number that contains the revision number of the device.

The vendor ID, product ID, and revision number values are obtained from the USB device descriptor.The following table describes the possible registry entries for the vvvvpppprrrrr key. The USB driver stack considers these entries as read-only values.

Registry entryDescriptionPossible values



Supported on Windows XP and later versions.

Indicates whether the operating system queried the device for Microsoft-Defined USB Descriptors. If the previously-attempted OS descriptor query was successful, the value contains the vendor code from the OS string descriptor.

  • 0x0000: The device did not provide a valid response to the Microsoft OS string descriptor request.

  • 0x01xx: The device provided a valid response to the Microsoft OS string descriptor request, where xx is the bVendorCode contained in the response.



Supported on Windows Vista and later versions.

Indicates whether the USB driver stack must ignore the serial number of the device.

  • 0x00: The setting is disabled.

  • 0x01: Forces the USB driver stack to ignore the serial number of the device. Therefore, the device instance is tied to the port to which the device is attached.



Supported on Windows Vista and later versions.

Indicates whether the USB driver stack must reset the device when the port resumes from a sleep cycle.

  • 0x0000: The setting is disabled.

  • 0x0001: Forces the USB driver stack to reset a device on port resume.
