Abstract
A system includes a logic device configured to cause the system to perform operations. The operations include requesting, from a peripheral device coupled to a host device, a device descriptor of the peripheral device, receiving, from the peripheral device, the device descriptor including at least two configurations. A first configuration includes an audio communications protocol having a plurality of selectable audio bit-rates and a second configuration including a plurality of selectable audio bit-rates and burst-rates. The operations further include selecting, from the first configuration and the second configuration based, at least in part, on a configuration of the host device, wherein the host device is configured to select the second configuration when the host device is compatible with the second configuration and select the first configuration when the host device is not compatible with the second configuration.
