"unplug the device too much power to re-enable USB devices"

Every time i plug my mouse (razer naga) on any USB port it says "unplug the device too much power to re-enable USB devices", the mouse used to work perfectly but now i can't use it for more then 5 seconds without showing that notification and disabling my USB ports. Can somebody please give me a solution for this?
(Sorry for the bad english, i'm from brazil.)

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.

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.

Hey HoustonSmith, using to much power generally means a short. Do not use this cable, the lighting cables have a history of failure; shorting out. If within one year of purchase date take it to Apple, the cable also has a one year warranty, if short is do to manufacturing flaw and not abuse Apple will replace it free! Otherwise a new cable is around $30. You could also try a reset or restore, but don't think a glitch is your problem. If you do try to restore, just remember to make backup copies of all the info / data on this iPod to your computer first, then attempt to restore. Good luck. Cheers.

Cannot use this device too much power camera

Read all the web traffic on the camera connection kits not working after the iOS 4.3 upgrade. Is there a fix out yet from apple.

this is an old issue - since 4.3 was released. as part of that release for whatever reason, apple change the amount of power it would support in a device connected via the camera connection kit. some devices still work fine, some don't. the work around seems to be to connect the devise using a powered usb hub. The kit works fine for what it does, it just does not provide as much power to an external device as it did prior to ios 4.3.

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!

MBP disconnects IPhone everytime saying the USB is drawing too much power?

Hi Guys,
Today I went and bought myself a new Mac Book Pro 13".
Tonight I've been transfering all my files over from my old MacBook and everytime I try to connect my IPhone 3GS by USB to my Mac a message comes up straight away saying "A device conected to your computer is drawing too much power, apple has disconected this device to prevent damage occuring to your computer"
I have tried to connect my phone numerous times while it has been conected to the power cord and also running on battery.
It also took my new Mac a good half an hour to recognise my external hard drive was connected and let me use it..
I have had this problem once or twice with the same IPhone and my old mac so im thinking it may be a problem with my phone considering it is 2 years old now?
But then again, my old mac that is nearly 4 can still connect to my phone when my new MBP can't.
Any help would be appreciated.
Thanks,

Use a self powered USB hub.

I don't have anything else plugged into my MBP, so I am confused as to what's going on. This problem has never happened before. MBP is less than a year old - about 9 months old. HELP

Get a powered USB hub.

HT4106 How do I use a midi keyboard on GarageBand with my iPad? When I try it says the device cannot be used as it requires too much power. However, I have given the midi it's own power source.

How do I use a midi keyboard as an input device on garageband? Its an oxygen 61 board. I'm using an iPad camera connection kit and a separate power source for the midi but each time it says it cannot use the midi as it requires too much power.

I have the same problem with my iPad and 61. Sometimes it says device not supported and sometimes it rants about power - any solutions anyone ?
