Questions tagged [winusb]

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, and 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, which 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.
