I have a Mac Mini and an iSight I've been happily using. I added two LaCie Mini Hard Drive and Hub units under the Mini. The first drive got plugged into the Mini, and the iSight and second drive got plugged into the FireWire hub on the first drive. At this point, both drives worked, but I couldn't get video from the iSight. The Mini recognized the camera was there, but all I got was a black screen for video.So I bought a Belkin powered FireWire 6-port hub (F5Uf26) and plugged everything into it. Now the iSight and the disk drives all work. Lesson: Not all hubs are created equal. I knew that about USB and Ethernet before. Now I've just added FireWire to the list.
