I have a UD-3900 docking station that was working great until recently. The Ethernet and Display adapter do not work anymore. I think the docking station *only works* as a USB hub (haven’t checked the audio adapter)
I turned off the docking station, uninstalled the DisplayLink software, ran the cleanup tool and reinstalled the DisplayLink software and still have the same issues.
I have an old plain DisplayLink adapter (UGA-165) that works when connected to the UD-3900 as a plain USB hub. In other words, UGA-165 works but UD-3900 does not.
The only thing I can think of that has changed is that I installed the Windows update KB3199209.
