Hi.
Opened a tiny speaker amplifier from China and found the audio inputs connected also to a mini USB receptacle traces.
The analog USB has born !
[ The brown wires are output to speaker. There is a 3.7V cell under the board. IC is 8002B ]

I've come across a lot of computer speakers with a Plug N Play to a USB. maybe something like that

The prostitution of USB. First was upper side band; kidnapped to universal serial bus, then used as a 5V connection, then a charger for whatever, now as audio link, with disregard to the signal carried. What matters now are the wire terminals because are available free to the masses as leftovers from discarded cell phones...
