Hi, my brother has an early Mac Mini which only has two USB ports in the back of it. One he's uses for the keyboard and the other he uses for a wireless internet doddle. He's bought a WD external HD one that needs two USB ports (one for data, one for power). He bought a crappy USB hub, but it didn't deliver enough power to the HD. Idealy I think he should get a firewire USB hub as he doesn't use his FW port. Can anyone recommend a good Mac friendly unit price isn't too much of an issue as I'll probably treat him if I find a good one.
