Hi, sorry for the delayed reply! It passed all the compatibility tests. I've attached the diagnostics zip also...

Hi, I'm just wondering if there's been any update on this? Thanks!

This is probably not directly related to DisplayLink, as we are just the video part of this dock, and this sounds like a general USB problem.

I see you have the USB 3.0 controller:

Fresco Logic xHCI (USB3) Controller FL1009 Series
Driver Provider: Fresco Logic
Driver Version: 3.5.100.0
Driver Date: 2013/03/07

I think these were quite early USB 3.0 host controllers. It's possible this is having problems when there are a number of high bandwidth USB3.0 devices on the bus. It sounds like the Host controller or hub in the dock are locking up.

Have you tried connecting the dock to a USB 2.0 port to bypass the Fresco host controller and see if that shows the same issue?

Like usual in a internet forum yes I have exactly the same problem.
Every thing is fine until I use my webcam. Than the PC friezes I lose my network connection etc. Using it on USB 2.0 no problem. But it is very slow. I have connected two screens, gigabit Ethernet webcam and everything over USB 2.0 is not a fun to use. So please help us to understand better the problem or give us a hint how to fix it.
