A customer found that some of their remote users were having problems logging onto internal web sites over VPN when using the Targus Universal Docking Station's GbE port.
By The Targus DocKtor The Dell Venue™ 8 Pro is $249. Indeed, this little PC and it is a real PC-runs Windows®8.1 Pro, not Windows RT™, or like an iPad®, or like a Chromebook™.
When I first started using a universal dock even I, the DocTar, had trouble getting my head around the difference between using an old fangled snap-in proprietary dock (sometimes called a "port replicator" - example below) and using a "universal dock".
After making sure my Lenovo X1 Carbon had updated Intel USB 3.0 eXtensible Host Controller and Intel HD Graphics 4000 drivers, I still couldn't get my Targus Universal Dock to connect to USB 3.0 - even after using the X1 Carbon's USB 3.0 port! In fact, the Intel USB 3.0 eXtensible Host Controller did not show in the Device Manager.
