Power the hub off the car(switched with ignition perhaps) and cut the power wire in the USB cable?
I recently upgraded my system and i installed a MediaPad 7 "
and use the USB port via otg cable to connect a USB hub
memory pen and keyboard;
the problem is that after stand by the hub is powered from tablet and it
drain his battery...
