Device Installation without an INF File

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.

Demonstration of automatically installing the generic Windows WinUSB.sys driver using only firmware descriptors on the TI Stellaris LaunchPad. From Brandon White.

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.
