Need pinout for a Dell Precision T7400 internal usb "flex bay" connect

The Dell Precision T7400 has a 10 pin connection on the mobo labeled "Int USB". In the available documentation, Dell says it is an Internal USB connection for their Media Card Reader but no where do they provide the pinout for the connection. In addition, there appears to be multiple versions of this connection depending on the model of machine Dell produces. A photo of the T7400 is available here,

You'll notice that this is different than other versions that usually only miss the tenth pin and this one is missing the second, third, and tenth.

I've spent many hours trying to find any information on this pinout. I've search and read many forums, I've called Dell's tech support all to no available. All I want is the pinout, you'd think that wouldn't be that big of a deal.

Any help is appreciated.

I myself have this same issue. The r6410 cable won't fit into this connector on the mobo and this is the only available port. Maybe there's a different cable that needs to be used for this?

I also need this info. I was wanting to hook up a TEAC CAB-200 Card Reader w/BlueTooth, and it seems I have the wrong cable.

Base off an article I just read it looks to be what they call an "Intel style easy connector". Here's a link (http://www.directron.com/installusb.html) I just got a multi reader with usb 3.0 and want the functionality of the additional usb 2.0 and multi card reader. gonna look for the Intel connector I suppose.
