Actually, I just needed an active port to via OTG to operate a Xbox360 controller to the tablet. My old stroke hatt unfortunately experiencing a cable break, therefore a stroke with exchangeable cable was needed. The power supply is gewessen irrelevant for me since I already have an AC adapter and the supplied China firecrackers anyway is not an option!
BUT !!! A single USB port is powered in 2sec interval and with 5,45Volt at 520mA (whether original power adapter or one with 5V @ 2000mA) How to get the idea to solder the ground of an electrolytic capacitor to the jack, the eh not connected is, to me, however, remains a mystery! (Attention hot swap is not given)
