https://doc.micrium.com/display/DOC/Audio+Class+Overview#AudioClassOverview-FeedbackEndpoint It seems such a feedback endpoint is now required by the standard: "The USB 2.0 specification states that if isochronous OUT data endpoint uses the asynchronous synchronization, an isochronous feedback endpoint is needed."
