WinUSB a generic driver for devices that don't fit a defined USB class. The driver was introduced with Windows Vista and is also usable on Windows XP systems. The driver is not usable on earlier Windows editions. The driver supports control, bulk, and interrupt transfers.
New! You can now install WinUSB devices without having to provide a device-specific INF file. How to install WinUSB.sys without a custom INF From Microsoft.
My Host Applications
These are my .NET host applications for accessing devices that use the WinUSB driver. The applications are identical except for the programming language. Each includes an example INF file to match the device's Vendor ID and Product ID to a device interface GUID.
