Can anyone tell me what exactly the J11 connector on this board is? The front USB connectors attach to it with a small ribbon cable. The pin block on the cable (mobo end) will fit into a COM port on a new Asus mobo i'm putting in this case. Basically, I'm wondering if I can still use the front USB's with the new mobo by plugging into the port it'll fit. Clear as mud? Thanks. PS - I already have the 6513 manual...it's not mentioned in there.
