My iPhone 4S won't draw power from my new Mophie Juice Pack Plus since an endless string of the same message popped out of my Mac screen -

"Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled.
To prevent damaging your computer, the USB device drawing too much power has been disabled. Other devices may have also been disabled. When you disconnect the device drawing too much power, your other USB devices will be enabled again."

Would appreciate if anyone can help me figure out a way around this costly inconvenience??? Sorry, I'm no brainy like most of you guys! I like the accessory before Mighty Mac winged about it drawing too much Power from thy kingdom! Thank you, MacMates.
