[Avid-L2] USB 3.0 spec to USB 2.0 compatability and optical?

From what I see there are an extra 5 connections to the USB 3 connectors.  These connections are deeper so the usb 2 cables will still plug in but not connect to the 5 new pins.  I'm reading the extra 5 provide for a separate trans and receive to speed up data transfer.  I see mention of optical versions.  Can someone elaborate on the extra pins and the optical side.  I'm googling and seeing pictures but I've yet to play with a computer with the new standard.  I have read the USB 3 is backward compatible.  If so would the new Black magic pocket scope work being plugged into a usb 2 or does it need the extra bandwidth of usb 3?
