Power management
1) You can disable the Ethernet chip via hubpower
2) The driver can be sent to suspend2, while the consumption drops:
echo "0" > "/sys/bus/usb/devices/$port/power/autosuspend" echo "auto" > "/sys/bus/usb/devices/$port/power/control"
3) Linux, apparently, is not able to do suspend of a device therefore if so to drive the driver with the activated GPIOs in suspend, it will constantly Wake up and fall asleep back. Consumption does not seem to be growing much:
up + high 22.2 up + low 17.4 down + low 13.3 down + unexport 13.2
