Gig Ethernet and Mouse Issues
Not to beat a dead horse here, but I have the exact issues with this same Targus ACP70USZ docking station. The Ethernet never worked right (would never negotiate to Gig speed), and I may have been able to deal with that, but the mouse lagging was the biggest thing I could not deal with. Just moving the mouse across the screen would pause (for up to a second or more) then jump to where it was supposed to be. I have read many others having this issue. This dock was almost $200 (from DELL) and is attached to an XPS12 Ultrabook (Windows 8) Tablet/Notebook convertible. I have the latest DisplayLink Software (version 7.2M0), but nothing I tried made a difference. I have replaced it with a USB 3.0 HUB from Plugable (7-Port) and connected my external monitor with the MiniDP connection on the side of the XPS12. Everything works smoothly (mouse too). The Targus dock is apparently at fault here.
