Abstract:
Embodiments of the present disclosure relate to methods and apparatus for peripheral device discovery, the detection of orientation of a connector having multiple degrees of rotational symmetry, and the provision of appropriate signal paths between a host device and a peripheral device. Some embodiments provide a characteristic impedance within the peripheral device that is coupled between rotationally symmetric contacts of the connector and thus enables detection of the connector orientation. The value of the characteristic impedance may be used in some embodiments to determine the type or model of peripheral device. Some embodiments are concerned with the enablement of appropriate signal paths to a peripheral device having a transducer (e.g. a loudspeaker) coupled only to rotationally symmetric contacts of the connector, such as headphones implemented in a “balanced” configuration.

Claim (Index 68):
A data controller for controlling transfer of data between a host device and a peripheral device via a connector of the host device, the connector comprising a plurality of contacts having n-fold rotational symmetry, wherein n is an integer greater than one, the data controller comprising:\n a path controller for enabling signal paths between circuitry of the host device and contacts of said connector, wherein the path controller is operable to enable separate signal paths to each of at least first, second, third and fourth contacts of the connector, wherein the signal paths to said first and second contacts are for the transfer of respective positive and negative audio signals for a first speaker of the peripheral device, and wherein signal paths to said third and fourth contacts are for the transfer of respective positive and negative audio signals for a second speaker of the peripheral device.
