Hi Guys
This does sound like it could be hardware with the device not appearing on the USB bus. Are you all using the same Targus product (ACP71 - with the laptop PSU)?
When you have issues, how much of the dock appears on the USB bus? Can you use device manager and "View devices by connection" to see if it is just the DisplayLink chip that is not appearing or if the USB 3 hub in the dock is also not appearing? Might help diagnose the issue.
Thanks
Wim
