MacBook Pro USB error message - "drawing too much power"

When plugging in my iphone, I get an error message into my MacBook Pro that reads "Because a USB device is drawing too much power from your computer, one or more of your USB devices have been disabled." Both USB ports say the same error message. Please help!

Are any other USB devices connected when this happens?

Your computer isn't meant to give that much power to a usb powered device. If you want to charge, then use the ac adapter and plug it into a wall outlet, if you are just syncing, then ignore the message.
