Every time I dock my laptop when it is already on or undock my laptop (with or without pressing the undock button) I get a blue screen. It looks like it is blaming usbhub.sys+63fd. There is nothing plugged into the laptop or dock USB ports. I am up to date with all drivers from Windows and my dell service tag. Windows XP pro 32bit. Not configured with a domain, just a regular workgroup laptop.
