RE: Dell D1000 Docking Station
A bad USB port on the laptop seems unlikely if your video and LAN traffic are working correctly given that they're also flowing through your laptop's USB port. You can certainly test another USB port on that laptop (assuming that system has more than one), although even that wouldn't be a conclusive test since all USB ports on a system are often wired to the same controller chip. Do you have another laptop you can test with? Otherwise, the best way to rule out drivers would probably be to get the latest version available directly from DisplayLink, which is the company that makes the chips that enable those docks to carry video and other traffic on a USB cable. Head over to DisplayLink.com for those. Good luck!
