Overview of Microsoft-provided USB drivers
This article describes the class drivers, generic client driver, and the parent composite driver that are provided by Microsoft.
Microsoft-provided USB drivers for controllers and hubs
Microsoft provides the following set of drivers:
For USB host controllers and hubs, see USB host-side drivers in Windows. You can develop a custom host controller driver that communicates with the USB host controller extension (UCX) driver. For more information, see Developing Windows drivers for USB host controllers.
For handling common function logic for USB devices, see USB device-side drivers in Windows.
For supporting USB Type-C connectors, see Type-C driver reference.
Other Microsoft-provided USB drivers
| Device setup class | Microsoft-provided driver and INF | Windows support | Description |
|---|---|---|---|
| USB | Usbccgp.sys Usb.inf |
Windows 11 Windows 10 |
Usbccgp.sys is a parent driver for composite devices that supports multiple functions. For more information, see USB Generic Parent Driver (Usbccgp.sys). |
| USBDevice | Winusb.sys Winusb.inf |
Windows 11 Windows 10 |
Winusb.sys can be used as the USB device's function driver instead of implementing a driver. See WinUSB. |
Microsoft-provided USB device class drivers
Microsoft provides drivers for several USB device classes approved by USB-IF. The drivers and their installation files are included in Windows. They're available in the \Windows\System32\DriverStore\FileRepository folder. For more information, see USB device class drivers included in Windows.
Microsoft defines setup classes for most devices. IHVs and OEMs can define new device setup classes, but only if none of the existing classes apply. For more information, see System-Defined Device Setup Classes Available to Vendors.
USB driver frameworks
Microsoft provides a driver framework for some types of USB devices that do not have their own USB device class specification. Vendors who want to create these types of devices should develop a device driver that uses the specified framework for the device type.
Currently, Microsoft provides the following driver frameworks for the following USB devices:
USB biometric devices
Microsoft supports USB biometric devices (fingerprint readers) by providing the Windows Biometric Framework. For more information see Biometric Framework overview.
