Actually, the case I was referring to was something different -- I have a
Tyan 1598S, which has 2 UHCI controllers built-in to the motherboard.
Only one is actually connected on the ATX panel -- the other is just a
header on my motherboard.  Naturally, my system shows up with 2 virtual
root hubs (UHCI), but I only have access to one of them.
