The only difference I can see between late Series 2.x and 3.x (4.x pending) is the inclusion of the HWE (hardware stack). Be interested to see if you installed the HWE on Series 3.x, if then the docking station works as expected. There's also something called 'DisplayLink' for Ubuntu, not sure if that applies to your situation though. Sorry, but I've little experience with docking stations.
