Defines transfer direction (see ENDPOINT_OUT and ENDPOINT_IN)). buffer_or_len Either a string (when sending data), or expected data length (when receiving data) To avoid memory copies, use an object implementing the writeable buffer interface (ex: bytearray). callback Callback function to be invoked on transfer completion. Called with transfer as parameter, return value ignored. user_data User data to pass to callback function. timeout Transfer timeout in milliseconds. 0 to disable. """
