We finally got our USB C plug breakout prototypes put together and now its time to test! of course we love to use our own breakouts when verifying functionality so here we're using our switchable USB adapter to check functionality: power, ground, D+ and D-. if a device enumerates we know its good! we tested the CC line by plugging it into an apple wall adapter: they're picky about having a 5.1K resistor on the CC pin.
