Hi, I have a MacBook Air with Mac OS X10.6.2 and until now, I understood that my Superdrive was the only thing that would not work with a Hub. I recently had trouble using the wireless network and resorted to the ethernet. I purchased and installed a Trendnet Ethernet adapter and found that it also will not work with a Hub. It works fine when I plug directly into the USB port. Do I need a powered Hub and will that work with my Superdrive?? Thanks.
