Post Script.
I finally got my Genius Optical mouse to function(not a waste of £25 then) and my Genius Wizard Pen also.
However I think that I'm not going to get any XP safe drivers for my Hewlet Packard 8200 series CD Writer.

Bluddy Adaptec and Roxio.
I guess this means I'll have to buy a new one.B*gger!
Incog.
