is controlled by the same control signal, it is not designed to be individually controllable.
And its control signal is GPIO-2.
If you are controlling the power(V-BUS) of usb-2.0 with the script you presented here
The power(V-BUS) supply of usb-3.0 should also be controlled at the same time.

However, the above answers will not solve your problem.
Because you already have control over the power of usb-3.0 .
What image was used
What is the problem in doing so
I think that it is better to present your problem more concretely.
Hi t4_4t,
thanks for your reply. I'm running a arch linux installation from https://archlinuxarm.org as a headless mail server. For backup reasons I would like to use the usb ports. With the script I mentioned, I managed to activate the usb2.0 ports, but the usb3.0 port has still no power.
Are you quite sure, that both are handled via the same gpio? With the Android image both ports are functioning quite well, so there's no hardware fault.
Best regards,
Christoph
