This is a good question...the problem of usb host power is not solved yet and an external hub is currently needed. At the beginning I remember I just tried to see if the usb voltage could be gpio controlled, now the other options I'm able to think of are a pin which needs to be configured in the Tegra pinmux or a voltage out of the power regulator. I don't know more but it's time to check on this again now...
