I've noticed recently that the USB 2.0 ports are NOT working on the docking station.
They are still powered, and devices plugged in will charge, but, they are not showing up on the mac, unless I move them into the USB 3 port on the dock.
I've downloaded the latest 1.3.1 software to check, and also rebooted the hub.
Any thoughts on what might be the issue?
Thanks in advance.

I am having similar issue. The USB Port on (left side of) my MacBook Air (Big Sur 11.2.3) was not recognizing the secondary monitor (AOC e1659FWU) at all. For awhile my monitor wasn't "powering up" and now that is is (randomly) it is lit up but purple and my laptop doesn't recognize it at all. I've tried everything! I thought maybe it was the cord because when I first purchased it, I had a similar problem but then it resolved itself for a few weeks. Now I am wondering if it's the monitor itself, the cord or what!? I don't have time for this! Does DisplayLink monitor these threads?? It sounds like a lot of people are having this issue today.
