Define active? For $13 I highly doubt it's a powered signal amplifier to be honest. That, and the fact that it only works with USB 1. (which works over a larger distance than the spec out of the box anyway) sounds kinda fishy. They say "USB 2.0 just connects and disconnects" Which is a symptom of either using too long a cord, or having a bad cable.
I'd be glad to be proved wrong though
