Fwd: HACKBERRY USB problem

Yes, this is why I edit a10_ehci.c

Hackberry has two external USB connectors in one package, and two not soldered
connectors. One on top, and one on bottom side of the board. I
soldered one (howto:
http://jas-hacks.blogspot.ru/2012/10/hackberry-a10-extra-usb-ports.html).
I think USB configuration looks like:
A10 USB1 -> GL850G (4-port HUB) -> upper port on external connector
and not soldered connectors.
A10 USB2 -> RTL8188CUS (WiFi chip)
And I assume, A10 USB0 OTG -> bottom port on external connector.

I tried to use all available ports:
root@:~ # usbconfig
ugen1.1: <EHCI root HUB Allwinner> at usbus1, cfg=0 md=HOST spd=HIGH
(480Mbps) pwr=SAVE (0mA)
ugen0.1: <EHCI root HUB Allwinner> at usbus0, cfg=0 md=HOST spd=HIGH
(480Mbps) pwr=SAVE (0mA)
ugen1.2: <product 0x8176 Realtek> at usbus1, cfg=0 md=HOST spd=HIGH
(480Mbps) pwr=ON (500mA)
ugen0.2: <USB2.0 Hub Genesys Logic> at usbus0, cfg=0 md=HOST spd=HIGH
(480Mbps) pwr=SAVE (100mA)
ugen0.3: <Mass Storage Device JetFlash> at usbus0, cfg=0 md=HOST
spd=HIGH (480Mbps) pwr=ON (500mA)
ugen0.4: <PS2+USB Mouse Targus> at usbus0, cfg=0 md=HOST spd=LOW
(1.5Mbps) pwr=ON (100mA)

As expected, all ports work, except USB0 OTG (bottom port on external
connector).

No, I haven't this problem. All ports work correctly at boot and after.

And/or, maybe do it something like it done for OMAP4:
sys/arm/ti/omap4/pandaboard/pandaboard.c
