+ This Audio function is compatible with USB Audio Class
+ specification 2.0. It implements 1 AudioControl interface,
+ 1 AudioStreaming Interface each for USB-OUT and USB-IN.
+ This driver doesn't expect any real Audio codec to be present
+ on the device - the audio streams are simply sinked to and
+ sourced from a virtual ALSA sound card created. The user-space
+ application may choose to do whatever it wants with the data
+ received from the USB Host and choose to provide whatever it
