Cannot charge iPhone 5 because USB is "using too much power"

Last night I tried charging my iPhone 5 on my MacBook Pro and everything went fine. However, when I tried to do the same thing today, every time I would plug my device in I would get an error message saying that the USB device is using too much power and has been disabled. Is there anyway to override this so that I can charge my phone?

It'll still carry the Apple warranty. My suggestion would be to bring your Macbook along and show them, even if you go to Verizon. You're better off at the Apple store anyway. If it turns out the cable isn't the problem, the diagnosis is free at the Genius Bar and one way or the other your problem should be fixed. Just make an appointment first.

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.

Have you tried an SMC reset and PRAM reset?
SMC Reset
Shut down the computer.
Unplug the computer’s power cord and disconnect peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.
Reset PRAM
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P and R.
You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
If that doesn't help, perhaps re-installing the 10.7.2 update using the combo (unless you already tried this):
OS X Lion Update 10.7.2 Client Combo
repairing disk permissions before and after updating.

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.)

IPad won't sync. Using "too much power". Help?

When I go to plug my 4th gen iPad into my Macbook Pro, it says I need to unplug the USB device using too much power, referring to my iPad. It has always worked before but as of late i have not been able to connect my iPad in order to sync it. Any Help, thoughts, suggestions greatly appreciated.

Do your cameras support Picture Transfer Protocol (PTP) and/or USB Mass Storage Device Protocol (http://support.apple.com/kb/HT4106), and if so do you need to change a camera menu setting in order to enable it ?

Get "using too much power" message when charging with USB

I have a 4th gens iPod Touch that appears to have a number of issues:
1. get "using too much power" message when charging with USB
2. can't re-boot
3. unable to access iCloud Backup, Ignore and Settings button inactive
4. unable to unlock unit when using the Home button to turn the unit on

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

I can no longer charge my iPhone5 through either of my macbook pros. I get the error message that a USB device is using too much power. Can anyone help?

I reconnected the original powered hub that I thought probably caused the problem and this time it shut down the whole computer. When I rebooted everything now works perfectly. The system reset. I tried another powered hub and it didn't have the same effect so the old one is heading for the bin and with fingers crossed all systems are now working perfectly. Trying to reset PRAM or reset the SMC didn't work but causing the same power issue did. Thanks for your input though. It did get me to think what was the original cause.

Camera connection kit w/USB says cannot work uses too much power

When using the camera connection kit /USB the message cannot use device it uses too much power pops up!

What are trying to use it with ? If you are connecting it to your camera then does your camera have a setting on it to enable PTP (Picture Transfer Protocol, Pictbridge) or Mass Storage Device ? If you are trying to use a third-party card reader or a flash-drive with the kit to copy photos/videos over to the iPad, then a lot of them require more power than is supplied to the iPad's port - if you have a powered card reader or a single-card reader (i.e. not one that has different slots for different types of memory card) then that might have a better chance of working

Error cannot use device the connected USB device requires too much power this error appeared when I added my camera

Error appeared when I connected my camera to iPad I used a camera connection device error cannot use device t he connected USB device requires too much power
Thanking you

Some cameras are designed to use the power suppled via USB when they're plugged into another device, usually a PC or laptop. The iPad does not supply sufficient power for a camera. The iPad Camera kit allows for either a camera to be plugged in only for the transfer of photos, not as a power sourse, or the removal of the SD Card from a camera so it can transfer photos as an alternative.

Lacie "using too much power", USB disabled, can't access ext HD?

Last night, moving items to my Ext HD, i got an error message about the USB "using too much power" and then it disabled it.
I'm using a 15'' 2006 Macbook with 10.6.7 operating system.
I've googled the issue and have run out of ideas.
The Ext HD is a 500GB LaCie Little Disk New Pack USB2.0 Black
Restarted the macbook.
Booted the macbook into safe mode.
I've tried plugging something else into both my USB ports (it detected the item, a camera card reader) and was usable.
When I plug in my Lacie Ext HD now using its usb cord, the blue light on the Lacie flashes as if its detectable/inuse but there's nothing in my Mac menus showing access to it.
HELP ?
Error Message:
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.

Maybe the disk will work through a separately powered USB Hub?

HT4101 When connecting my camera to my IPad mini via lightniing to usb camera adapter,I get "The attached accessory uses too much power" .Any solutions?

When I connect my Ipad mini to my camera via lightning to usb camera adapter all i get is a message "The attached accessory uses too much power."Any solutions

It depends on the camera, but some have a special mode for offloading photos but not trying to charge the camera through the USB port. For others, you may have to pull out the SD card (if that's what it uses) and use the Lightning to SD card reader instead.
Maybe if you told us what camera you are connecting, somebody here with the same model can give you more specific information.
