How to get Sharing Switch to work with Dell WD19DCS Docking Station?

I have this sharing switch and the Dell WD19DCS Docking Station.  I have the docking station hooked up to my dell laptop and the sharing switch to both the laptop (switch A) and my PC's (switch B) USB 3.0 ports.  There is a USB 3.0 male to male cable connected to the switch and the docking station, but the docking station does not recognize the sharing switch.

Is there a way to install them or is there another sharing switch I can try?
