No video / USB Display Adapters

[Mblackburn]

Hi
I just got the Targus Dual video Docking Station and I can't get any video. I have been looking through the forum for ways to trouble shoot, and I tried the steps in the "Debugging ussues on Windows with DisplayLink". I am runing a Dell Vostro 3550, which has USB 3.0. The drivers seem to install fine and it will work as a USB hub, but I cannot get it to see the NIC, or make video. I can see the DisplayLink service and it's started, but in the device manager there is no USB display adapter. I have tried everything in the HOWTO (to my knowledge at least). I have attached the support files. I gotta be missing a step or something.
WIN 7 Pro
Dell Vostro 3550
Thanks
