USB consuming too much power -notice

I get all the time notice/warning that: "USB-device is consuming too much power. Hub/concentrator which the device is connected will be shut down." During this writing I got the notice three times.
I don't have anything connected to my Macbook Pro (bought year 2006), not even mouse, just power wire.
What to do? I don't see any difference after the notice (that something has been shut down). It is just popping up all the time and makes working with the computer really annoying. It might be related situations the when computer is moved, or something.
Can I swich some USB-port/device off? Thank you in advance already!

I had the same problem which arose just after I lost an external hard disk (Lacie 1 Tb started to make loud clicking sounds). I'm not sure whether I lost the hard disk because the break down of the USB-ports or whether I lost the USB-ports because of the break down of the hard disk (?).
Either way I get the same warning and after resetting the SMC and the PRAM I reinstalled the OS. Nothing of it helped. Instead I went to the authorised Apple service partner. And now it gets scary for real.
Apparently the USB-ports are an integrated part of the logic board (not just a card) and I need to get a new logic board to fix the USB-ports. Price 10.000 DKK. A new MacBook Pro will set me back 13.800 DDK (divide those figures by 5,8 to get US $).
I'm in some kind of chock. The MacBook is not yet 18 months old and works fine - except for the USB ports that I do need for connecting my camera, external hard drives and my iPhone......

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?)

FOR GURUS: Over Current Notice - USB device drawing too much power

Hi,
When I plug a USB extender cable to any USB port on any Mac tested so far, I get the warning:
"USB Over Current Notice. The USB device is currently drawing too much power. The port it is attached to will be deactivated".
In fact, that freezes the Mac mouse and keyboard until the USB extender cable is unplugged, and renders the used USB port unusable until the next restart.
What is going on? Such extender cable worked fine until Virtual PC was open with Windows XP XP2 in safe mode on an iMac G5 (20-inch) with Mac OS X 10.4.3. A 1GB flash pen was inserted, and its files were seen via "My computer". Then the flash pen was taken out (without properly ejecting it via Windows) and someone inserted a 2.2 GB USB hard disk, which froze the Mac and caused the reported problem from that moment.
So it seems that the USB cable is now somehow defective, but I wonder if it could be fixed, since it does not seem to have any internal circuit but just the USB connectors and cables. So I wonder what is going on...
Thanks.

¡Hola, Gabriel!
USB Overcurrent Protection issues arise when one or more of the USB devices draw too much power or, by adding a device to a USB hub, one exceeds the current budget for the entire chain. A detailed explanation can be found in this article, where it states:"Should the cumulative current drawn by a group of downstream ports exceed a preset value, the overcurrent protector removes power from all downstream ports. Overcurrent circuits are used to protect against catastrophic device failures, software errors that lead to devices turning on when the current budget has been exceeded, and user-caused events such as the shorting out of connector pins."See also "USB: Hub Description" for important information on self-powered vs. bus-powered UBS hubs.
Your Apple Pro keyboard is a bus-powered USB hub. Some displays continaing USB ports may act as either bus-powered or self-powered hubs: one has to consult the display's documentation for details.
• If USB Overcurrent problems arise using a bus-powered, third-party USB hub, try a self-powered hub or connect the USB device directly to one of the built-in USB ports on the computer itself.
• If USB Overcurrent Protection issues arise when a device is connected directly to one of the built-in USB ports on the computer itself, then the peripheral device or its cable is either damaged or defective.
Note that you can not put two bus-powered hubs in series. In addition to the article "USB: Hub Description", see also "Apple Pro Keyboard: Devices Connected to Hub May Not Work."
Good luck!

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."

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.

USB Mouse Draining Too Much Power

I have a 22" Cinema Display and I keep my USB Power Mac Mouse attached to the USB port in the back, but now both ports give the error message that the "USB Device" requires too much power. I can plug it into the keyboard and it works fine, does anyone know what is going on?
Brad

Bummer. Oh well, it's lasted 41/2 years, and the Display is still looking good. Thanks for the info, I figured it was that but I wanted to be sure. It's strange both USB ports went out at once. Thanks again.

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.

I want to download pictures from a Sony Memory Stick Pro Duo to my iPad 4. There is no cord for the camera and the USB dongle requires too much power through the camera connector kit. Any good solutions?

Another way. You can use a USB flash drive & the camera connection kit.
Plug the USB flash drive (works the same with an SD card) 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.)

HT4101 What does it mean when it says that the USB device requires too much power?

What does it mean when it says that the USB device requires too much power, when using the ipad lightening pin camera connection kit?

Just that. The iPad allocates a certain amount of power to that port. If the device you're trying to plug in wants more than the iPad is willing to give, it'll trigger that warning.
If it's something that you just must hook up you can try using a powered USB hub, but results are mixed at best.
What are you trying to hook to your iPad?

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.

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.

USB Microphone drawing too much power

When I plugged my Blue Microphones Snowball Mic into my Macbook today, I received the following error message:
USB Over Current Notice
A USB device is currently drawing too much power. The hub to which it is attached to will be deactivated.
The Mac is plugged in. There is no other USB device attached. The last time I used it (a few weeks ago), it worked fine. I have plugged it into both USB ports and received the same error message. The mic does not have a power source except the USB cable.
Any potential resolutions?

See this, USB and FireWire Quick Assist, for help.
