USB Devices Disabled due to "using too much power", but no devices plugged in

I keep getting the following notification
USB Devices Disabled
Unplug the device using too much
power to re-enable USB devices.
The thing this the only thing plugged into my Macbook Pro is the charger.
Any ideas on how to fix this?

Unusual.
I would start with SMC and PRAM reset:

  • Lightning to usb camera adapter saying attachment uses too much power

    Can anybody help me please as I brought this cable and I get a message saying accessory unavailable or attachment uses too much power . Thanks in advance

    If it's an Apple adapter, take it to an Apple store for replacement.
    Try this  - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.) No data/files will be erased. http://support.apple.com/kb/ht1430

  • Camera Connection Kit "Using Too Much Power" Error

    I'm trying to connect my iPhone 6 to my iPad Air 2 using the Apple USB Camera Connection Kit so I can transfer some video files.  I get an error that says "Accessory Unavailable - The Attached Accessory Uses Too Much Power".  Both devices are running the latest version of iOS.  I've tried hard reboots on both and no change.  This used to work fine with my iPad 2.  Is my camera connection kit defective?

    My camera just started doing this on my MBP too! I have no idea what to do

  • 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.

  • 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?

  • 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.

  • 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 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.

  • HT4106 unplug the device using too much power to re-enable USB devices

    iPad min cannot be changred, it shows
    unplug the device using too much power to re-enable USB devices

    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.

  • 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?

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

  • 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.

  • 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
