Windows 7: How to determine an enhanced USB Host Controller

How to determine an enhanced USB Host Controller

I clicked on Device Manager > Universal Serial Bus controllers. Five members of the Intel 82801G (ICH7 Family) were listed. One of the five was described as a USB2 Enhanced Host Controller - 27CC.

My PC has 3 USB ports. How can I determine which is the Enhanced port?
What if I plugged a USB Hub into a port other than the enhanced one, would it work better or not at all?

That is not one of the ports. It is a controller. The enhanced controller is used on all the USB ports. I believe that is the USB3 controller. So you don't have 1 enhanced port, but rather 1 enhanced controller being used by all ports
