This section describes the generic WinUSB driver (Winusb.sys) and its user-mode component (Winusb.dll) provided by Microsoft for all USB devices.

In versions of Windows earlier than Windows XP with Service Pack 2 (SP2), all USB device drivers were required to operate in kernel mode. If you created a USB device for which the operating system did not have a native class driver, you had to write a kernel-mode device driver for your device.

RELATED: How to Use the Windows Device Manager for Troubleshooting You’ll see information about Unknown Devices in the Device Manager.To open it on Windows 10, 8.1, or 8, right-click in the bottom-left corner of the screen or press Windows Key + X and select Device Manager. The Google USB Driver is required for Windows if you want to perform adb debugging with Google devices. Windows drivers for all other devices are provided by the respective hardware manufacturer, as listed in the OEM USB Drivers document. For certain Universal Serial Bus (USB) devices, such as devices that are accessed by only a single application, you can install WinUSB (Winusb.sys) in the device's kernel-mode stack as the USB device's function driver instead of implementing a driver. This topic contains these sections: Automatic installation of WinUSB without an INF file. The package provides the installation files for FTDI USB Serial Port Driver version 2.12.16.0. If the driver is already installed on your system, updating (overwrite-installing) may fix various issues, add new functions, or just upgrade to the available version. NI Device Drivers provides popular NI instrument drivers you can use to control NI and third-party hardware. NI Device Drivers is a bundle that features most NI instrument drivers, including NI-DAQmx, NI-VISA, NI-SCOPE, and NI-SWITCH.

Windows USB (WinUSB) is a generic driver for USB devices that was developed concurrently with the Windows Driver Frameworks (WDF) for Windows XP with SP2. The WinUSB architecture consists of a kernel-mode driver (Winusb.sys) and a user-mode dynamic link library (Winusb.dll) that exposes WinUSB functions. By using these functions, you can manage USB devices with user-mode software.

Winusb.sys is also a key part of the link between a UMDF function driver and the associated device. Winusb.sys is installed in the device's kernel-mode stack as an upper filter driver. An application communicates with the device's UMDF function driver to issue read, write, or device I/O control requests. The driver interacts with the framework, which passes the request to Winusb.sys. Winusb.sys then processes the request and passes it to the protocol drivers and ultimately to the device. Any response returns by the reverse path. Winusb.sys also serves as the device stack's Plug and Play and power owner.

Note WinUSB functions require Windows XP or later. You can use these functions in your C/C++ application to communicate with your USB device. Microsoft does not provide a managed API for WinUSB.

This section describes how to use WinUSB to communicate with your USB devices. The topics in this section provide guidelines about choosing the correct driver for your device, information about installing Winusb.sys as a USB device's function driver, and a detailed walkthrough with code examples that show how applications and USB devices communicate with each other.

This section includes the following topics:

Windows Support for WinUSB

The following table summarizes WinUSB support in different versions of Windows.

Note Yes¹: All SKUs of this version of Windows support WinUSB on x86-based, x64-based, and Itanium-based systems.

Yes²: All SKUs of this version of Windows support WinUSB on x86-based and x64-based systems.

Yes³: All client SKUs of Windows XP with SP2 service packs support WinUSB. WinUSB is not native to Windows XP; it must be installed with the WinUSB co-installer.

No: WinUSB is not supported in this version of Windows.
