Hello everyone. I read on various sites that the new Macbook Pros don't support two full power (500ma) USB devices at the same time on its built-in ports and will error out if you try. This concerned me as I often have two full power devices plugged in. Today I connected two full power devices at the same time. One was a powered USB hub driving a keyboard, mouse, and USB headset. The other is a Simpletech 250GB USB hard drive. Everything worked fine. Not only did it work fine, but the new MBP has absolutely NO problem spinning up that external drive; my previous (2006) Macbook Pro would fail to spin it up about 4-5 times, then finally get it going. This impressed me greatly! I guess this means the statement of only one full power device at a time is false? Maybe we should try to get this updated on the sites that claim that.
