INTRODUCTION
This article introduces an update that installs version 1.9 of the WinUSB driver file and of the WinUSB library file on Windows operating systems.Windows USB (WinUSB) is a generic driver for USB devices that was developed at the same time as Windows Driver Foundation (WDF) for Windows XP Service Pack 2 (SP2). The WinUSB architecture consists of a kernel-mode driver (Winusb.sys) and a user-mode dynamic link library (Winusb.dll). Note WinUSB driver packages that are built by using Windows Driver Kit for Windows 7 can automatically redistribute and install version 1.9 of the files. During driver package installation, the package checks the computer to determine what version of WinUSB is currently installed, and then the package updates the files to 1.9 if they are an older version.For more information about WinUSB and the versions that are included with various versions of Windows, visit the following Microsoft Developer Network (MSDN) website:
