It was the same whether plugging into a USB 2 or 3 port. I also tried downloading the Fresco USB drivers posted earlier in the thread, but upon installing it said it couldn't find any Fresco USB controllers (my dock apparently has a Texas Instruments Root USB Hub).

If you have a TI Root Hub in your laptop, the Fresco drivers are not going to work. You need to update the TI drivers, which can be found here:

And for anyone else wanting to update the USB 3.0 drivers in their laptop, the latest drivers are linked from this article in our knowledgebase.

I would have expected it to work when plugging into a USB 2.0 port. When you connect to a USB 2.0 port and have the issue, can you use device manager, and "View Devices By Connection" and drill down the USB bus to see how much of the dock has appeared on the bus? Is the root hub of the USB dock there or is it just the DisplayLink USB chip that is missing?

Wim - I updated to the latest Ti USB3 drivers, but I'm still experiencing the same problems. After the Ti USB3 update I now have an Unknown Device showing up under the Generic USB Hub section in Device Manager. However, the Texas Instruments USB Root Hub and XHCI Controller show up fine.

I've attached a couple Device Manager screenshots if that helps any. The first is normal view (devices by type) of USB, second is devices by connection. Under device by connection I don't see the Ti USB.

Thanks for your help.
