USB Keyboard and Mouse connected to dock stop working after windows loads.

I have a user that uses a Dell D630 laptop connected to a docking station with a USB keyboard and USB mouse at his desk.  Two days ago the USB keyboard and mouse started acting up.  When the machine posts I can access BIOS fine, the user can enter his PGP password fine but when windows loads the mouse and keyboard stop functioning.  The mouse light and num lock lights turn off and will not work no matter what USB port on the dock they are plugged into.  Device Manager does not see them.  They work fine when plugged directly into the laptop.  They also work normally through the dock when the PC is booted into Safe Mode.

I have tried a new dock, new peripherals, new chipset driver.  The only minor success I had was removing all the USB controllers and rebooting the laptop.  The keybaord and mouse worked one time in normal mode.  After a reboot the problem started all over again.

Does anyone have any ideas?
