a usb hub that connects to the GPIO pin's
I was thinking of a on board power relay for the raspberry pi from the hub
Now I'm even more confused.
I was thinking of a board like
raspberry-pi|---------------------|raspberry-pi_usb-|
| power-supply| >|---------------|usb-wifi|-------|
power plug-in----> usb-hub|------> ether-net|------>|
