What does it mean when it says that the USB device requires too much power, when using the ipad lightening pin camera connection kit?
Just that. The iPad allocates a certain amount of power to that port. If the device you're trying to plug in wants more than the iPad is willing to give, it'll trigger that warning.
If it's something that you just must hook up you can try using a powered USB hub, but results are mixed at best.
What are you trying to hook to your iPad?
