My USB ports Using too much power with nothing plugged in.

So i have this macbook pro mid 2009 model. Whenever i boot the computer up, there's this message that comes up. USB ports must be shut off because its using too much power blah blah blah. Theres nothing plugged into them!
Everything works, camera and all that, but the USB ports.
Do i need to download anything to get them to working?
Is it with the logic board?
or idk what to do!
Please help!

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.

  • USB port drawing too much power. The device that is plugged into it will be

    I get this strange message every so often, sometimes more often than other times. It says:
    USB port drawing too much power. The device that is plugged into it will be deactivated.
    There are only two things plugged into the USB-The keyboard and mouse. When I get this message, the mouse freezes. If I jiggle the mouse cable where it is plugged into the USB, it comes back and everything is fine until this message comes up again.
    Ever seen this before? What did you do?
    Thanks for your help.

    Ahh I guess I could have figured that out by reading your hardware tag huh...
    So it's giving you the message when booting up from a cold system with NO devices attached? (Not even the keyboard and mouse?).
    How long before you get this message?
    After you get this message, if you plug the mouse in to either USB port (As each port is a seperate bus), to clear the alert, and go into About this Mac, and More info, if you expand the USB info for each bus. Is there anything there that appears to be out the ordinary? (IE Only showing one bus, Showing a device plugged into a bus that isn't plugged in?)

  • 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.

  • 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

    help

    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.)

    strange - try the second port.
    possibly a bad cable.

  • How to reset USB port after too much power draw message

    Hi everyone,
    I have the brand new MBA which I use for work and I tried connecting a USB hub yesterday to it.  Once I did the computer immediately shut itself off and after doing some HW troubleshooting for a bit, I unplugged, got back running and saw the error message:
    I have done all sorts of reading online and just can't get my USB ports to work at all anymore.  I've tried plugging in my apple keyboard directly to both ports, and tried memory sticks but no luck.
    Beyond that I have tried the steps for resetting the VRAM (or whatever it's called) and tried an SMC reset (though for that one there are several sets of differing keystroke instructions).  I have also had the computer "unplugged from power all night (and in sleep mode) but nothing.
    Can anyone please help me?  I am fairly computer savvy so do want to try quite a bit more before I take it to an apple store as I just don't have time to deal with it.
    Thanks

    i had the same problem after leaving my macbook pro overnight with the printer cord plugged in. even though i had unplugged the printer, computer still showed the message. suggested reset didn't work. but what did work was:
    1) shutting down computer
    2) turning printer on and reconnecting to macbook with macbook still off.
    3) powering up macbook
    4) removing printer USB cable AFTER macbook fully booted up.
    voila, no more message, all USB ports functioning!

    I ve upgraded my MBP to SL and since 3/4 days ago i ve been experiencing problems whit the USB port. A nice "error window" pop up saying that one or few USB port is driving too energy and therefor will be shut down. The error continued to pop again many times, sometimes 5 of this windows pops up simultaneously. Yesterday i took a decision (a big step) and reset my mac (after trying other solutions and check ups such as reset the parameter random access memory (PRAM) and nonvolatile RAM (NVRAM) and hardware check ups). Been there done that. I ve decided to install first tiger and no error was shown, then i ve upgraded to leopard and again no error was shown... At last when i ve finally installed SL and reboot the system the first thing that showed up was was that nice error...At least this time it shouws up only at start up... I must conclude that there is a kind of bug in the SL system is there anyone that has an alternative solution to this annoying problem, apart from changing mac ....=D....?

    Marco,
    Just to let you know you are not alone. I have a similar problem with my MacBook but the message does not seem to affect operation. It occurs when I plug in my USB speakers, but the speakers work just fine and the message does not reappear unless I unplug them and plug them in again. I chatted with a specialist at an Apple store and it was suggested that I make an appointment with a "genius". Because it does not appear to affect operation, I am inclined to wait and see if 10.6.2 changes this behavior.

  • IPhone not charging, "USB port draws too much power"

    I've tried charging my iPhone with 3 different cables, 3 different socket chargers and my macbook.
    Won't charge, the socket chargers turn off, the macbook displays the aforementioned error.
    I haven't dropped it, soaked it in water or anything.
    Unfortunately my year warranty expired last month.
    Suggestions?

    Welcome to the discussions,
    have a look at this article, http://support.apple.com/kb/TS1286 , "Symptoms...An alert message indicates the USB device cannot operate because it needs more power than is available."
    And
    If the issue persists and you are using a Mac, try resetting the USB connection by following the steps in http://support.apple.com/kb/HT1317

  • 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 ?

  • 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.

  • 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.
