    A colleague borrowed a NanoPi R1S to play with Ethernet and usb man in the middle techniques, and returned it with a usb cable.

    Surprisingly, when plugged in all by itself, the cable identifies as a keyboard! So I tore it down to see what was up, and found an IC embedded in the A connector.

    A bare USB-A connector soldered to a tiny green PCB with an 8-pin surface mount IC on it. There is an unlabelled an unpopulated pair of pads that fit a resistor or similar with white silkscreen around them.
