On Apple's store page for the wired keyboard, it says, "*Devices that draw high power from the USB connection, such as iPod, hard drives and some flash drives, can only be used with the new keyboard when it is attached to the aluminum iMac." I have a mac pro... shouldn't that be able to power those as well as an iMac would? Is that page just out of date? Or is there some reason it will not work with the Mac Pro? Or, what about an ACD?
