To support both, WinUsb and Legacy driver APIs we need to abstract classes that depend on driver API details and then implement two sets of the actual classes: one for WinUsb, and another for the Legacy drivers, so we can choose in runtime which objects should be instantiated, depending on what type of driver we have underneath this API.
