Methods and apparatus for mipi soundwire integration

A USB host device comprising:

• a USB host controller configured to communicate with a device via USB signaling;
• and
• a processor configured to:
• cause first audio bus data to be transmitted to the device as the payload of USB transactions through the USB host controller;
• and
• receive second audio bus data from the device as the payload of USB transactions through the USB host controller.

A method comprising:

• processing first audio bus data received via USB transactions through an upstream-facing port configured to communicate with a host controller via USB signaling;
• causing the first audio bus data to be forwarded to one or more audio bus peripheral devices via an audio bus protocol through at least one downstream-facing port configured to communicate with the one or more audio bus peripheral devices,
• processing second audio bus data received from the one or more audio bus peripheral devices via the audio bus protocol through the at least one downstream-facing port;
• and
• causing the second audio bus data to be forwarded to the host controller via USB transactions through the upstream-facing port.
