No adapter - 10.6.8
 

Just bought Atlona AT-HDAir product and was trying to install on my MAC Book Pro (Snow Leopard - 10.6.8). The WUSB software is installed and shows that there's WUSB connection with the base however, I've tried various versions of Displaylink drivers (including 1.7b2 for Lion) but I don't see any external or second adapter except my original adapter on OS X!
