I would like to make some noise for a USB hub via the power port. I've always wondered why there were 6 pins per side on the power connector of the SP3. I've been secretly hoping the power brick actually does more than supply power via the usb port, and is in fact a true USB data port to be enabled in a future firmware update. I've been looking, and even searching on this forum for an explanation, or even a guess about why the simple AC adapter has as many pins as it does. Does anyone have any ideas?
