how to make basic circuit of usb audio/ video device

random google returns
https://source.android.com/devices/audio/usb -- there is at least something USB audio Class
https://www.extreamsd.com/index.php/technology/usb-audio-driver -- a lot of practical hw compatibility issues
https://en.wikipedia.org/wiki/Audio_and_video_interfaces_and_connectors#IEEE_1394_.22FireWire.22 -- the article does not list USB
