Abstract
This application relates to methods and apparatus for transfer of data between a host device (400) and a peripheral device (300) via a USB Type-C connector (100; 304) of the host device. A data controller is described that has a path controller (309, 310; 706) for establishing signal paths between circuitry of the host device and contacts (101) of said USB Type-C connector. The path controller is operable in at least first and second modes. In the first mode the path controller establishes separate signal paths to each of at least first, second, third and fourth contacts (A6, A7, B6, B7) of the USB Type-C connector and a plurality of the established signal paths are for transfer of analogue audio data. In the second mode the path controller establishes a pair of signal paths to only a subset of said first to fourth contacts to provide a differential digital data path.
