I have similar problems with my dock (Targus USB3 Dual Video) and my Surface Pro 2. It works most of the time, but now and then it stops to work. For me it starts to work again if I unplug the power to the dock, wait for 20s or so and then plug the power to the dock back in again (the dock remains connnected to the Surface Pro the whole time). After a little while the DisplayLink driver kicks in and my external display connected to the dock is back in action and USB + phisical network connected to the dock work again.
Maybe this is something that can help you out as well?
