MacBook Air SuperDrive does not work with powered Hub. You can see what happen when I connect the drive through my multimeter with 500mA range. The scale librates wiggle around 300mA. In this case, the drive does not work (does not spin). Maybe I need more "low-constraining" multimeter to estimate the power requirement of the drive.
Wow all i can say is wow it uses so much freakin power
