Unfortunately it doesn't allow you switch configurations while a test is running, because it holds the device lock during each test. Why not use g_file_storage or g_mass_storage for your tests? You shouldn't have much trouble adding the appropriate SuperSpeed descriptors (one bulk-IN and one bulk-OUT endpoint).
