Just as an aside: were there such systems?  I remember USB2 as having 
replaced 1.1 immediately, not least because they were compatible.  I 
suppose it would have been possible to have had 1.1 on board and 2 via a 
card.
The USB2 specs were released in April 2000, how long would it have taken 
before motherboards with 1.x were no longer being sold?
