I have 3 of them (on 3 computers, not daisy chained) and I run them passive. There ARE active ones but I have never been in a position where I put too much of a power requirement on a hub. So I wonder now, Bob, will your run passive? Will it run at all, just not power everything at once? How many ports? (Mine passive ones run 7.) That's the kind of geek things I think about.
