B10 Support For USB Hub

Here in Brazil B10 does not support a USB HUB. So, you can not use the USB Data port to record video and use Android auto via cable at the same time. I know there is wireless Android Auto, but it does not allow me to use my 4G/Wifi router connection becouse my phone is connected to the Android Auto wifi network. I've noticed too that, if I try do connect B10's media central to my 4G/Wifi router network, Android Auto sound system has some intermittent glitches.
