Hi all- I have noticed that mice these days come with a USB connector. They also come with an adaptor that let's you plug them into a PS2 mouse port. What exactly does this adaptor do? Is it a trivial item, with the smarts in the mouse/PC or does it convert from PS2<-->USB? David -- http://www.piclist.com hint: The PICList is archived three different ways.
