I have an Inspiron 8200 and a docking station.  I am plugging the wireless receiver for a Logitech Freedom Optical Keyboard/Mouse set via both PS2 ports.

My keyboard works fine and the software 'realizes' that it is attached, so I can use all of the special function buttons.

My mouse (and just a plain MS Wheel Mouse I tried) when plugged through the docking station, do not function properly.  The mouse works, but non of the 'extras' work (such as the wheel, wheel button, and thumb button)  The mouse is not detected under hardware in the Mouse Properties, just the ALPS is detected.

It works fine, if I plug into the laptop directly, as opposed to the dock.

Thanks
