I get a kick back. There is no 5vdc source on the mainboard available. I found various sources for DC 3.7V but I am not sure if this will be enough for a standard 5VDC USB device. Maybe i have to try around with the available voltage supplied by the mainboard. The next thing is it is hard to measure while the mb is off the frame. The pins are really really tiny so the risk of melting something is growing with this hurdle.
