I'm a brand new MAC convert and I have to say I LOVE IT. But here's my problem. I have three FIRELITE USB drives from my PC that I obviously would prefer not to replace. My USB port on my 17" powerbook does not supply enough power to run even one of them. I have a USB hub that I am using (have to plug it into AC) but it's not a great solution. For one thing, the AC adapter on the hub weighs more than my Powerbook! Anyone know if I can get a USB hub that plugs into the FIREWIRE port on the computer so I can get enough power without an AC adapter?
