I see a usb sign on the esata port so it's a combo, any usb device works on that but I am about to find usb 3.0 drivers because windows default driver doesn't see it as a sub 3.0 port. I tried forcing a driver and I had to reinstall windows again. How can I know this port is USB 3.0?

USB3.0 ports have the Blue insert. – Moab Jun 13 '12 at 21:31
There's no such thing as an esata/usb combo port; they are entirely different. – psusi Jun 14 '12 at 1:15
@psusi: Yes, there is. – Dennis Jun 14 '12 at 11:25
@Dennis, interesting... looks like the industry has gotten ahead of the standards bodies. – psusi Jun 14 '12 at 14:25

I'm not sure I understood your main question correctly. If you question is

Is every E-Sata / USB combo port a USB 3.0 port?

the answer is No.

How can I know this port is USB 3.0?

Refer to the manual / documentation of your motherboard, laptop or expansion card.
