Update
Alright folks, I was able to get some help from AppleCare and here is what I learned:
So far I have:
1. Restarted with no peripherals plugged in ... didn't fix it
2. option - ctrl - shift - power button ... nope
3. command - option - P - R - power button ... nope
She is now consulting with another source. I asked if she had access to the new keyboard and an ipod, she said they don't yet. I even dictated the 'Low USB Power Notice' message to her, I guess she hasn't seen it before.
If you connect a
powered usb hub to the usb 2.0 port of the new aluminum keyboard, you
can charge and sync an ipod.
I was then transferred to a hardware specialist who was even more informative. He stated that the new keyboard does have two USB 2.0 ports; however, you can only connect
one (1) high-powered USB 2.0 device to the keyboard at a time. The mighty mouse and iPod are both high-powered USB 2.0 devices, so you can't connect 'em both at the same time to the keyboard. You should be able to connect just an iPod and a USB 1.1 device, and still have full functionality of the iPod (charge and sync).
The problem: Even with only an iPod nano plugged into the usb port on the keyboard, it still had that 'low power' notice come up. He assured me that this is not supposed to happen, so he walked me through reseting my power management (or something like that). That involved shutting down, removing ,all peripherals, the A/C adapter and the battery, then holding the power button for 10 seconds. This still didn't fix the problem.
So he has contacted engineering and will be getting back to me within 48 hours. I told him about you guys and how one of you was able to use your ipod through the new keyboard. He will even be reviewing this thread to see what the rest of you have said.
He also put in a request to clarify Apple's web page describing the functionality of the USB 2.0 ports on the keyboard.
Anyways, sorry for the wall of text. I just thought some of you would be interested to know what is going on.
Cheers.
