Actually, the 'backchannel' endpoint is used for both adaptive, and asynchronous modes, so does not prove anything.
According to the protocol:For adaptive audio source endpoints and asynchronous audio sink endpoints, an explicit synch mechanism
is needed to maintain synchronization during transfers. For details about synchronization, see Section 5,
“USB Data Flow Model,†in the USB Specification and the relevant parts of the Universal Serial Bus
Class Specification.
.....
An adaptive audio source IN endpoint is accompanied by an associated isochronous synch OUT endpoint
that carries Ff. An asynchronous audio sink OUT endpoint is accompanied by an associated isochronous
synch IN endpoint.
