I have plugged a Dell docking station into your USB 3 Sharing Switch and the front USBs to 2 laptops. I have connected to the docking station a single monitor, keyboard and mouse. At first I see one of the laptops and everything works. When I switch to the second laptop, the mouse is activated on the second laptop but I do not see the second laptop on the monitor. I still see the screen from laptop one. Then, if I switch back to laptop one, the mouse only works on the laptop, not the monitor. Its as if the monitor is frozen.
I have switched the USB cables around and still the same behavior.
