This Article describe an approach enabling WinUSB to use any of the Configurations exposed by the USB device. The main aim of WinUSB is to reduce development cost by exposing a user-mode application level USB API, this, save the time and effort of developing a USB Driver and enables the developer to focus on application logic development.Īs of Windows 8.1, Comparing to a fully fetched USB Kernel mode driver, WinUSB has few limitations, one, is the fact that while a USB device might expose multiple Configurations to choose from, WinUSB supports only the default Configuration ( the first one ). WinUSB is Microsoft user-mode framework for communicating with USB devices. ![]() This Article is designated for experienced C++ developers, It is assumed that the reader has basic experience with windows OS driver development. ![]()
