Abstract
Interface circuitry is provided for a host device, the interface circuitry for controlling data connections between the host device and a peripheral device. The interface circuitry comprises: a discovery module, operable to detect mating of a connector of the peripheral device with a connector of the host device, and to store an indication of the current mating status of the connector of the host device; and a data connection management module, configured to: responsive to detection of mating between the connector of the peripheral device and the connector of the host device by the discovery module, establish a digital data connection between the connector of the peripheral device and the connector of the host device; responsive to detection of a deactivation event and based on the stored indication of the mating, deactivate the digital data connection; and responsive to detection of an activation event and based on the stored indication of the mating, re-establish the digital data connection between the connector of the peripheral device and the connector of the host device.
