Precision 5810 Built March 2015 No Internal USB 3???

I found, and had a hard time believing, that my new Precision 5810 (Mft. 20150313) does not have internal USB 3.0. Could this be true???  I noticed it from the Windows 7 messages telling me that the optional Realtek Card Reader "could perform faster" if connected to an USB 3.0 port.  So, I purchased a PCIe USB 3.0 4 port card, 3 external, 1 internal.  When I install it and go to make the connections, I find that the header cable going from the motherboard to the back of the Realtek card reader is a 9 pin F to F.  The internal USB 3.0 connection on the card I added is a Type A Female. 

Since this is such an oversight on Dell's part, could you send me a USB 3.0 Type A Male to 9 Pin Male header cable???

I definitely need to have the card reader on my new high-end workstation working on USB 3.0, USB 2 is just not acceptable.
