When I plug my iPhone 5 into the USB connection a message pops up saying a device drains too much power and the USB port has been disabled and no longer recognizes my iPhone...HELP

Hi G.Iphone.5,

Here is an article that has information and links to the iPhone troubleshooting assistant that I would recommend going through for this article:

iOS: Device not recognized in iTunes for Mac OS X

The main step I would try is this:

Check USB connections. iOS devices require USB 2.0 to function properly. If you are not sure if your Mac has USB 2.0 ports, refer to the computer's specifications. Disconnect other USB devices, and connect your device directly to a USB port on your Mac.

Take care!

Which USB port are you plugging it into? Directly into your Mac computer or ? The Apple keyboards usually only have enough power to power a mouse - shouldn't be used to charge any device.

Yes, my first question would be similar to babowa's: not only which USB port, but what device? Are you connecting the iPhone to a USB port on a notebook, a desktop, a monitor, a keyboard, etc. I suspect this may related to the cause of the problem; as noted above, some devices are not meant to, nor capable of, powering other devices.

I hope you find your solution.

Sincerely,

Wynne
