My USB is dead after msg "USB drive draw too much power"...

I connected a digital desktop photo thing to my macbook through USB intending to transfer pics to that device; however, my macbook popped out a msg something like, "USB drive draw too much power..." then the Macbook shut down suddenly by it self. After I restart Macbook, my USB is completed dead... how can I revive it?
I tried plugging in wireless mouse or ipod ... USB has no reaction. Thank you for your help or input in advance!!

Same thing just happened to my Mini, my wife successfully used a SanDisk Micromate adapter to download photos, but when she tried to plug in her iPhone4 the dreaded USB drawing too much power ports will be shutdown msg appeared.  I can plug in the phone on my other Mac no problem, so its the Mini's usb ports.  Help anyone? SMC reset did not work.

  • WD Legacy External Hard Drive "Draws too much power from USB"

    I have a nice MacBook Pro running Leopard, a year or so old and I've never had any issues with it. I used a WD Legacy 250GB External Hard Drive for Time Machine to back up all my stuff. It has its own power source, and the USB cable works fine because I use it with my printer all the time. However, even with both the laptop and the hard drive plugged in, my laptop automatically disconnects the hard drive because the "USB is drawing too much power".
    It didn't happen when I initially backed stuff up on it, and it plugs in and works fine with a desktop. Is there any way to disable the automatic disconnect for drawing too much power through a USB? I don't understand how that's even possible because the external hard drive has its own power source, and I just want my stuff backed up. I could care less if it ***** the charge out of my laptop for a few minutes if that means it will work. I've considered getting a powered USB HUD, but wanted to get everyone else's opinion first. Thanks!

    Contact the manufacturer. I think the power pack for the drive is not functioning properly.

  • Thumb drive draws too much power on keyboard port

    My keyboard supported usb thumb drives in the past.  Suddenly it is giving not enought power errors if I insert thumb drives, iPhone or iPod into either of the ports on the keyboard.  These devices work just fine if plugged into the computer.
    Has anyone had this problem or solved it?

    I remember when I bought the Camera Connection Kit for my iPad2, there were several undocumented functions that you could do with it besides just transfer image files from a digital camera.  I think you could hook up a wired keyboard to the iPad (and use it), and attach USB sticks, and they worked.  But, then came an iPad update, and all that extra stuff miraculously stopped working, to be replaced with the "insufficent power" error message.
    I finally found a blog posting that said they had changed a power consumption number in a single line of code and this stopped all the extra things from working.  Something like changing a number from 50 down to 20 somethings.
    I seem to recall that their explanation for dumbing down the undocumented functionality was that these extra devices would decrease the battery life of the iPad.  Hmmm... I come from the PC environment where we say, "Well, let me make that decision and not you!"

  • Western Digital Scorpio Blue 640 Drive draws too much power in a MacBookPro

    I just received a Western Digital 640 gb (WD6400BEVT) Scorpio Blue Drive for my MacBookPro. I've noticed that the drives "Throttles" a lot, i.e. seems to accelerate/spin and slow down/stop in a way I've never seen in any other drive, and I've been through lots. It wouldn't be a problem if the computer didn't seem to be sluggish in response, much more sluggish than with the 200G Hitachi drive I had before. I will sometimes start typing something and the computer will be slow to react; I also see the spinning ball much more often.
    I contacted WD and was told that "It is quite possible that the computer cannot manage the capacity and energy demand of this drive. If the previous drive was under 250 GB, a 640 GB drive will encounter these issues."
    I'd never hear of this problem, and I'm really confused since the new drive has a lower rated energy requirement (it's a 5400 rpm vs 7200) than the previous drive. Has anyone else had these problems? Can someone tell me whether this is reality or obfuscation on the part of Western Digital?

    Hi Brody - what makes you think the 640Gb isn't a 'notebook' drive? I've a 640Gb one that's been in my Macbook Pro, although now it's in my Samsung Netbook.
    The unit worked perfectly fine in my late 2008 unit? It's a 9.5mm unit that as far as I know adheres to the 2.5" SATA specifications? Like I say, worked fine in mine.
    This is the unit in question: http://www.overclockers.co.uk/showproduct.php?prodid=HD-322-WD&groupid=701&catid =14&subcat=896
    ...or full specifications here: http://www.wdc.com/en/products/products.asp?driveid=683
    Even WD's spec says 'Big Capacity for Mobile Computing'.
    Personally I doubt whether this issue is with power - it's probably more to do with the random pausing that some machines experience with certain drives. I had it before I upgraded to an SSD back when I had a 500Gb 5400RPM Seagate Momentus for example - you can read about my experiences with there here: http://www.markc.me.uk/MarkC/Blog/Entries/2009/6/13Macbook_Pro_Hard_DiskUpgrade.html
    I know that doesn't help the original poster that much unfortunately, but I don't think it's an issue with the drive being inherently incompatible with the Macbooks/Laptops as such. Saying that, the OP has a 2.33Ghz MBP and I don't think the pausing issues apply that far back, well not in the same manner anyways.

  • Seagate drive quandary:  "USB device is drawing too much power"?

    I have a year-old Seagate external hard drive that when I plug in to a 2011 MacBook Air, it started saying something to the effect of "your USB device is drawing too much power and had been disable in order to aboud damage..."  I had been using this drive for some time, and this just started a few days ago.  I tried plugging it into a USB hub and directly into a USB on the MBA with the same result.  So I plugged in into my brand new 2012 MacMini and got the same messgae.  My initial conclusion:  the drive is dead.
    So I buy a new USB 3.0 Seagate compact external drive, plug it in and get the same error on my MBA and on the MacMini.  If that isn't odd enough, I have the exact same Seagate model plugged into my MacMini as the backup drive with no problems.  Any ideas??  Maybe I received a DOA drive by coincidence?
    UPDATE:  Tried the new drive on a Win7 PC and it recognized it fine.  Why would my 2011 MBA and 2012 MacMini not recognize the new drive?

  • 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 - 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

  • "A USB device is currently drawing too much power"

    I know it's a long post, but I just want to describe everything I've tried to do to solve the problem, so we can cut right to the chase
    Yesterday I got this message when I plugged in my external harddrive (which is working properly btw): "A USB device is currently drawing too much power. The port it is attached to will be deactivated."
    Today I haven't seen the message, but the USB port next to the Shift key on my MacBook isn't working very well.
    Well, actually it works when I plug in my other external harddrive (which isn't usb-powered). So it seems that there's nothing wrong with the USB port itself. It just doesn't have the power it used to.
    My USB-dongle from Cubase works fine. I tried another USB memory stick - it flashes very lightly and it won't mount. The other USB port - the one next to Caps Lock - works fine and it can even provide power enough for my MIDI keyboard and external soundcard.
    I've tried resetting the PRAM/NVRAM and the SMC as people often suggest when this problem is described, but it doesn't help.
    I've tried to do a full system check, and it says that there's no hardware errors.
    I can imagine, that some would assume that the USB port is fried - but it can't be when the externally powered harddrive works fine when using the port.
    I think is has to be some sort of software error. Is it possible that when OSX tells that "The port it is attached to will be deactivated" then the port needs to be reactivated somewhere?
    I'm really looking forward for your answers

    I don't know if this helps but...
    I have five 24" iMacs in a education lab that keep telling me "USB Current Overload," even though only the Apple keyboard is attached. It seems they starting giving me the message the first time I turned them on. However, after a great talk with an Apple Tech person, we deduced that it must be a driver I installed on the five machines. We came to this conclusion because when I boot the machine from the OS CD, the problem doesn't happen. When I reboot from the hard drive, the message incessantly pops up, even with just the keyboard and mouse (that it came with) plugged in. On one machine in particular, the message pops up so many times that I can barely use the machine.
    I have installed two external devices driver's on this machine, a Novation ReMote Compact SL driver and a TC Electronics 24 D firewire driver. I also have "frozen" these machines using DeepFreeze, which keeps students from installing things or chaning settings. My assumption is that one of these drivers is causing the bogus message. Since the computer works fine when booting up from the OS CD, this is the only thing that could be happening. Some other driver is causing the machine to think a USB device is drawing too much power. At least, I think this is what is happening. I'm still working on fixing this problem, but have not been successful yet with removing drivers.

  • Dual-USB External DVD/CD RW 'drawing too much power'

    Hello,
    I had to make an emergency purchase down my local electrical store because my internal drive has stopped working properly. So, bought one of these: (http://cnmlifestyle.com/) DVD/RW that is supposed to be mac compatible. It has two USB connections - one for power & another for data I presume.
    When I plug it into a USB port, a dialogue box appears saying 'Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled.' And so therefore there isn't any power to the unit... and it won't work.
    This appears immediately after plugging one of the two in. When I plug in the second USB connection a second, identical dialogue box appears. If I connect then re-start, two of the dialogue boxes appear...
    Might it be that this unit is not compatible with laptops? (there is no information about voltage on the unit).
    Many thanks,
    Jay

    Optical drives have motors and that makes them power hogs. If it does not get power from its own power brick, it could be overpowering your USB bus, especially if you have other USB devices connected.
    Have you tried swapping the cables on the Mac's ports? Some people report that the left- and right-hand ports produce difference power levels.
    If the drive does not have a separate power source, it was designed for mobile use on a notebook computer but someone in Marketing was not thinking about power issues when trying to jump on the mobile bandwagon.
    I see two solutions, the best listed first:
    1) return the drive for one that has a power brick self-powered)
    2) Purchase a powered USB hub (has a separate power brick). That way, the drive gets a lot of power from the hub. This one:

  • MacBook pro 13" mid 2010 "USB drawing too much power" HELP

    Hi, my MacBook Pro keeps coming up with a window about 30 after start up saying "USB drawing too much power" and none if the USB ports work neither does the iSight camera (green light is constantly on) and the headphone jack won't work! I have tried re installing OSX but it hasn't worked! Apart from an SMC reset and a PRAM what else can I try? Absolutely nothing is plugged in not a single cable or keyboard or mouse just my MacBook on its own, is it definitely a software problem or am I going to have to get apple to repair the hardware because I do not have that much money to replace a logic board and get apple to replace it themselves. Thanks in advance!

    I hope it works for you ...

  • New iMac 27"  and just plugged in a Apple USB superdrive and get message, "Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled."  I am trying to load Office mac2011  what to do?

    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.

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

  • Apple USB keyboard drawing too much power

    I had my apple slim keyboard for more than a year and it always worked perfectly.
    Last week I started receiving this error message at the login screen:
    "Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled."
    Changing the USB port used to solve the problem. Since this Sunday I can't get the keyboard to work on any USB port.
    No other devices are using the keyboard as an HUB and the iMac has all the latest updates installed.
    I tried on a Macbook and got the same result, while if connected to an HP laptop it works.
    I already tried:
    - changing USB ports on the rear of the iMac
    - attaching it on an externally powered USB HUB
    - resetting PRAM
    - resetting SMC
    - cleaning the contacts of the USB cable and the ports on the keyboardù
    - attaching usb devices to the ports on the keyboard will give them power, but those are not recognized by the system
    Any clues? I ran out of ideas...
    thanks

    It's related to the current drawn through the USB port itself which us monitored by the SMC and interpreted by the OS. Without getting too technical, Macs are better "tuned" to detect these issues. It sounds like your keyboard is dead or dying as it is drawing more than it's allocated current threshold. Solution, replace the keyboard. Some possible causes over time include, sweaty hands, humidity, coffee - it's the sugar over time that does the damage.

  • USB device drawing too much power...

    I have a Mac Pro 1,1 that until this last software update (10.6.7) was running fine. After the download and reboot, my computer is now riddled with the same 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 give further understanding of my set up, I am running an ATI Radeon 5770 video card with three monitors attached: on the DVI port is a 32" Samsung flat panel TV, and attached to the two mini DVI ports were two 20" Apple Cinema Displays connected via dual link DVI connectors (each of which was connected to two of the three USB ports on the hub in the back of the Mac Pro tower).
    So, after the software updated and the computer rebooted, the Apple Cinema Displays did not come back on (obvisously because the USB hub in the back of the tower was shut down).
    I have tried repairing permissions. I have reset the PRAM and I have reset the SMC. None of these have thus far worked.
    After a visit to Apple, the Genius told me that it was because there was some discrepancy with the other third pary PCIe cards that have in slots one, two and three. So I confirmed with him that if I pull the cards and reboot, the error message should go away. I pulled all third party cards from the slots and I'm still experiencing the same problem.
    I realize that this sounds like a logic board replacement. But I'm hoping there's someone else out there in the community who may have had a similar problem and may be able to offer any other kinds of work around.
    Just for the record, I am running an RME HDSPe card in slot 1, UAD 1 in slot 2 and UAD 2 in slot three. Slots four and five are occupied by the ATI Radeon 5770.
    Any advice would be appreciated.
    Thank you.

    If you don't have any USB devices plugged in, then your Mac may just be confused. Try an SMC Reset:

    Unplug whatever other devices you also have plugged into USB, and try again. Better not to plug the iPhone into a USB hub.
