Hello, I am playing with my robovero and just realized that the robovero itself doesnt seem to ever power the usb hub.  When I connect an external pc to the mini usb jack it powers oof the pc and I can see the devices on the pc.  If I disconnect the mini usb however, all the connected devices (usb wifi adapter and usb webcam) lose power.  Looking at the schematic, it seems that there is some switching circuitry that should be giving the bus power when an external pc is not connected.  Is this not true? 

I have the same behavior on both of my roboveros.
