WinUSB - USB library for PICs from Jan Axelson

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.

WinUSB is a .NET host application for accessing devices that use the WinUSB driver. Each includes an example INF file to match the device's Vendor ID and Product ID to a device interface GUID. There are two variants - VB.NET and C#
