If it were all micro, then it’s a matter of 2-wire vs 4-wire, and with a micro socket, you could hook up the A end into a powerbank or other supply, then just sniff the power- and data-lines with an LED each.
No light at all means a miswiring, power-only LED (can stick a resistive load to draw, say, 500mA from it) means power’s intact, data-LED lit even barely means something’s jiggling on that line vs being totally off.
I got some micro sockets so’s I could hook up, say, 5V fans directly to a usb port via generic cable vs via some weirdo adapter. All I care about is power, and no negotiation for anything above 500mA, so simple is good, but you could wire up something quick or just use that board above to do more thorough testing.
