Plugable Ethernet not working on UD3900

So I’ve had this problem for quite some time but with Windows 10 it has gotten much worse: I can’t get a wired connection via the dock - it only connects via wifi. I only have it on the machine I use the most so that is doubly frustrating. Running troubleshooter on the “DisplayLink USB Graphics Device” in Control Panel reveals “The driver for Plugable Ethernet is not insalled. Install the latest driver for this device.” but when I apply the suggested fix it can’t find a driver. There is also an “Unknown device” but of course it can’t find a driver for that either. Please help.
