I keep getting 'USB port is drawing too much power error'

I have an old 2010 13" MacBook Pro. Just tonight, it started giving me a 'USB port is drawing too much power' error. The only thing I had plugged in to my MacBook was my iPhone cable (without the phone) and an Intuos tablet I recently bought. At first I thought it was the tablet, because the tablet started acting wonky after that error message (it worked just fine earlier in the day).
After restarting, the tablet works with no problem so I thought the problem must be the iPhone cable. The thing is, I read in some other forum that a cable not plugged to the iPhone shouldn't draw power, and they said if it does then it's a sign for a short circuit. My iPhone cable is a little bit worse for wear, to be honest.
So my question is: Is the problem my cable and if it is is it dangerous if I use this cable to charge my phone with a USB wall charger? 2nd, Is there anyway to fix this other than buying a new iPhone cable?
Thanks in advance!

Thats a warning. if you continually get that warning with the iphone cable and you keep using it. You could eventually  disable that USB port.

    Sometimes you have to reset the SMC two or three times for it to work, don't know why. I've seen that error message before and 100% of the time it was fixed with an SMC reset. I suppose it's possible that your keyboard or mouse IS drawing too much power, do you have access to another you could try?

    If you just bought the iMac and the Sjuperdrive take the superdrive back and get a refund. The by any other brand external DVD drive that connects by USB and try that. Most come with a Y USB cable to allow you to connect to 2 USB ports to supply enogh power to the drive IF Needed.
    Or take both back and get a refund on both, you have 14 days to return it no questions asked, and buy another iMac and some other brand external DVD drive.

    If you are getting that message on a brand new Mac with nothing connected to the USB ports, take it back. It is broken.

    What do I do?

    Not Charge
    - See:      
    iPod touch: Hardware troubleshooting
    - Try another cable. Some 5G iPods were shipped with Lightning cable that were either initially defective or failed after short use. One symptom of a bad Lightning cable is the message you are getting.
    - Try another charging source
    - Inspect the dock connector on the iPod for bent or missing contacts, foreign material, corroded contacts, broken, missing or cracked plastic.
    - Make an appointment at the Genius Bar of an Apple store.

  • Error message (Because a USB device was drawing too much power)

    Hi Everyone,
    Bought recently a new macbook pro 13 inch with Retina display with 120 GB flash drive.
    Connected a non-apple CD drive to my macbook and after that started receiving this message: "Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled."
    initially I was receiving this message after I switch on my macbook but now after every 30 seconds this message pops up although I never connected anything to my macbook through its USB ports.
    Will highly appreciate for your help on how to get rid of this problem.
    Regards
    Homayun

    Try resetting the SMC
    Shut down the computer.
    Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
    On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
    Release all the keys and the power button at the same time.
    Press the power button to turn on the computer. 
    Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

  • "Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled." HELP!

    When I plug in my son's iPad I get this message "Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled." I only have one charger for this iPad all my other chargers are for iPhone 4s. I have pluggerd it in different outlets around the house and the iPad will not charge. When I plugged it on my lap top to back it up it gave me the warning message. HELP!!

    I have the same problem on my Air. The message first came up while my iPhone was connected to it for some time. Since then, it pops up ALL THE TIME, whithout anything being connected to the USB port, at what appear to be random intervals that vary between about one hour and a few seconds. I have tried resetting the SMC and  the PRAM, but no results. A quick search revealed that thousands of users are facing this problem, but Apple has yet to provide a solution. Please help!

  • "Because a USB device was drawing too much power from your computer, one  or more of your USB devices have been disabled.

    Here is the total error message:
    "Because a USB devce 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."
    Now in contrast to every other thread on this i get this error message eveytime i connect my soundcard (interface). Not when i start up the mac or anything, just when i connect the sound card. (the soundcard does not have its own power source but note that this has never happened before and i have had this soundcard for about a year!)
    It deactivates so i cannot use it.
    I have tried:
    Connecting the soundcard to my mothers mac -> it worked!
    Connecting an external harddrive to my mac -> it worked!
    so basically, i can't be the soundcard or the cable and it cannot be the mac USB port?
    I don't know what to do! i really need this to work! anyone got an idea??

  • Because a USB device was drawing too much power problem

    This message keeps popping up even when I have nothing plugged in. I have tried restarting and checking for viruses but there is none and the message still shows up. Now I can't even plug things is the USB port because its disabled. Please help.

    this is the message "Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled."

  • "Because a USB device was drawing too much power from your computer..." error withOUT any USB device

    Hi,
    I am getting this error since recently when I am using my MBP:
    "Because a USB device was drawing too much power from your computer..."
    The 'funny' thing: there is no USB device attached to the computer (only power and monitor cables).
    Why is this happening and what could I do about it?
    Appreciate your ideas?

    It's probably an internal hardware fault, but you can try this:

  • USB device drawing too much power error message

    When I try to plug my iPod into my computer to charge or update my music, I get an error message that says, " Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled." I've tried this while my computer was plugged in and not plugged in and it still gives me the same message. My computer is completely new, I've only had it about 2 weeks, my iPod is about 3 years old, but the actual iPod works great. It's just the USB cord that is giving me a problem. What is wrong and how can I fix it?

    My only option is to click "ok." It has already ejected the USB connection, so I don't really have any other choice. Here is the complete text of the 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."

  • Because a USB device was drawing too much power from your computer - bla, b

    In the last week or so, my iMac (Intel CoreDuo) started displaying an error message every 30 seconds saying "Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled", followed by some other useless "explanations" (which BTW can't even be copy/pasted). This has happened before (for about a year now) at every startup, but that was more acceptable; now that the message comes every 30 seconds it renders this machine unusable.
    I tried it with or without any USB accessories attached, with or without powered hubs attached, I reset the PRAM and SMC and reinstalled the OS twice. The only option I have left is to trow this machine out and buy a new one (believe me, it's not going to be a Mac).
    This shows not only the lack of quality of the hardware (crappy logic board and USB ports) but also a complete disregard for the annoyance these constant popping messages create to the end user when designing the OS. Just while writing this message I had to press the OK button about 10 times. It's AWFUL!!!

    Hi cimula. before you turn to the extremes have you tried reinstalling snow leopard. maybe you had a problem occur when it was originally installed and is missing a driver or something. also take it to an apple store if possible. take everything needed to run the imac and show one of the geniuses the problem and 90% of the time if you are nice and calm they will gladly help and diagnose the problem even if it is out of warranty. no promises it will be free it could be a hardware malfuntion. just dont force your self back to pc once all of the problems are gone you will love it again. i switched from pc which i had been using my whole life after a friend showed me his macbook and have never looked back. of course once and a while there will an error, problem or whatever but is it worth switching to a pc which has to have a security program running 24/7 to stay alive and sucking up all of the cpu and slowing you down? hope i am helping Dean
