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.

i plugged in my ipod and now i get the error message: Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled" - i have a MAcBook pro and now my USB ports do not work - can anyone help me ???
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?

I am having a problem when I plug my iPod into my macbook. When I plug the cable into my mac I get the following message - "Because a USB device was drawing too much power from your computer, your USB device has been disabled." CAN SOMEONE PLEASE HELP!
The rest of the message in the pop up window says "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."

I have a 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. -

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??Hi, ryankeenanrk.

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!

I am trying to upload photos from my digital camera. Every time I try to plug it into my USB, the following error message comes up: "Because a usb device was drawing too much power from your computer, one or more of your USB devices have been disabled."
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. HELPGet a powered USB hub.

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:

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.

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