        I think I have found an answer, at least for a similar HP model.
        It is not a standard PCIe circuit!

            NOTES:
            * The dc5700 supports Normal (or Non-reversed) layout ADD2
            (Advanced Digital Display 2) adapter cards inserted into the
            SDVO (Serial Digital Video Output) connector on the system
            board. This connector has the physical appearance of a PCIe
            x16 connector; however, conventional PCIe cards are not
            supported in this connector.

        So I guess there will be no USB 3 on that computer.

        Bob
