On my MacBook Pro with Retina Display, Why does the "USB Devices Disabled Unplug the device using too much power to re-enable USB devices" keep coming up after I unplugged the usb device?

On my MacBook Pro with Retina Display 15", that I purchased a few weeks ago, started coming up with the following message on my desktop:
"USB Devices Disabled Unplug the device using too much power to re-enable USB devices".
I unplugged the device and the message still keeps coming up.
This is what I have done so far to troubleshoot:
I shut down the laptop. When booting up I pressed the command+option+p+r at the same time. It comes up with a menu to reinstall OSX, Get help online, Run Disk Utility, etc. I choose the disk utility and repair the disk and then restarted.
The message keeps popping up and I can't seem to get rid of it. Why does the message keep popping up even though I don't have any devices hooked up to the laptop at all? Any help to reenable my usb ports and get rid of the messaage would be helpful.

I talked to Apple Support and we at least stopped the bleeding, a little bit. These are the troubleshooting steps I did before I contacted Apple Support:
1. Reinstalled OSX
2. Restore the last known good Time Machine Backup.
This did not fix my issue, so I called Apple Support and they told me this:
1. Turn Power off.
2. Wait 15 seconds.
3. Plug in Magsafe adapter.
4. Wait 15 seconds.
5. Hold down the Shift+Option+Power Button for 20-30 seconds.
6. Turn Power back on.
Ok, this stopped the bleeding a little, but as soon as I plugged in a Apple USB Superdrive
and a Apple Mini Displayport to VGA Adapter. This "USB Devices Disabled" pop-up pops up like every 30 minutes now. At least, it is not constantly popping up after I close it, so I guess it will do for the temporary. Going to contact Apple support, later, though to see what else can be done.

Try unplugging it. Give your iPad a reset by holding down the sleep and home keys for about 20 seconds (until it reboots) then try again.

Hey HoustonSmith, using to much power generally means a short. Do not use this cable, the lighting cables have a history of failure; shorting out. If within one year of purchase date take it to Apple, the cable also has a one year warranty, if short is do to manufacturing flaw and not abuse Apple will replace it free! Otherwise a new cable is around $30. You could also try a reset or restore, but don't think a glitch is your problem. If you do try to restore, just remember to make backup copies of all the info / data on this iPod to your computer first, then attempt to restore. Good luck. Cheers.

The messages is telling you that something that draws too much power was connected the USB bus.

To upload photos from my pc onto my ipad using a usb stick. I bought a camera connector kit and tried placing the usb stick onto one of the white square adaptors, stuck it into the ipad2 and I got 'the device uses too much power'' message. Pls help.

I am not very familiar with the ipad2. I wished to transfer some photos from my pc (not an apple pc but that is the only one I have) to my ipad2 as I thought it would be easier to cull them, edit, crop etc to create albums for our recent trip (the photos are already on the pc and no longer on the camera memory card). When I place the usb stick on the adaptor and stick it onto the Ipad2 I keep getting 'device uses too much power/ requires too much power' message. I read somewhere on the internet that a usb hub could be used to solve the issue but that did not work either. What am I doing wrong? Is there actually a way around this problem. If not why does apple sell this product for Ipad users at all?
Thank you for any help/ solution you can offer.
Regards

I'd ask that on the iPad forum.

HT4101 My ipad says the device uses too much power when I connect my camera

I brought my ipad 2 on holidays and have purchased the camera connection kit. I tried to download my photos and an error message came up saying that the device uses too much power! My ipad is powered up to 100% and I have closed any open files and it still says the same thing? Does this actually work or do I have to return it?

What have you connected to the kit ? The amount of power that is supplied to the kit is limited, and can't be changed - and a lot of card readers and cameras need more power than is supplied to it. If you have connected the kit directly to your camera then does your camera have a setting to enable 'mass storage device' and/or PTP (picture trasnfer protocol or pictbridge) ?

Has anyone found a way to download pictures fro Samsung Galaxy 3 phone to the Ipad air? I bought the lightning adapter but I keep getting the message device uses too much power. Any ideas?

You can't directly from a Galaxy phone. But you can certainly upload the pictures from your Galaxy phone to your computer and then sync them to your iPad via iTunes.

When I connect my Nikon coolpix S9200 to the camera adaptor I get a message saying this device uses too much power, how can I overcome this?

You are probably seeing this message because the camera uses the same port to charge it. The iPad can not supply the power to charge devices from it's dock connector. Also if you use the SD card adapter you are not using up the camera's battery for transferring the photos.

I made an extra backup on a USB device and now I can't get it back because "the device uses too much power". Why didn't it a few weeks ago and how can I use the device anyway?

because "it uses too much power"
I did'nt get that message a few weeks ago when I used Snow Leopard and now I can't approach the files I saved on the external disk.
Question 1: How do I solve the problem? (Without going back to Snow Leopard)
Q2: Why this parential supervision by Apple?

Get a powered hub
USB is cranky, you're not the first (probably not the last) to have this happen.

HT4101 my camera says check connected device. USB device uses too much power. I have got the photos on before with persistence but this is not working

Is the USB drive you are trying to connect a USB thumb drive or a USB hard drive?
I have 4 USB thumb drives - an old one at 250MB, newer ones at 1GB and 4GB, and a new one at 8GB. All work in the camera connection kit except the 250MB (requires too much power). Suggest you get a new USB drive.
Use your camera's SD card.
Another way. You can use a USB flash drive & the camera connection kit.
Plug the USB flash drive into your computer & create a new folder titled DCIM. Then put your movie/photo files into the folder. The files must have a filename with exactly 8 characters long (no spaces) plus the file extension (i.e., my-movie.mov; DSCN0164.jpg).
Now plug the flash drive into the iPad using the camera connection kit. Open the Photos app, the movie/photo files should appear & you can import. (You can not export using the camera connection kit.)
