I've been getting "one of your USB devices is drawing too much power" and my keyboard is disabled

This happens sporadically after the computer has been on for awhile. How can a keyboard or mouse draw too much power from the computor? These are the only things plugged in. Please help, I need my keyboard/mouse.

See "About This Mac" from the Apple menu in the menu bar, and there than under USB, for what's all connected to the USB controllers in your Mac. You'll be surprised, it's not only keyboard, mouse, or what else you use externally.
It also shows you what pulls how much current. Anything pulling the max current can be causing it, either due to a defect or some irregular configuration. Anyway, you should get pointers where to continue searching.

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.

Anyway to bypass a broken USB port? I got an error saying that my USB device was drawing too much power and had to shut off.

I have a macbook pro. I just upgraded to Mavericks last night hoping this would fix the problem, but it hasn't. I received this error message and now none of my USB ports are working. I researched some and people have told me to reset the nvram, yet it is still not working. I have seen Thunderport docks that include USB ports on them, but they cost around $200. Just seeing if there is some sort of adapter or clever way to get around this problem? I mainly use my USB port for a Wacom Tablet. I was thinking about replacing the logic board, but that would be my last option. also, when i plug my phone into one of the USB ports, it shows that it is charging my phone, but it doesnt show up on my computer.
thank you!

You may see if you can get a rise out of it by use of another reset...

Generally when combined total of items plugged into USB bus, where
ports are powered from one internal source, is too high, you'd get &
use a USB powered hub. This has a power adapter, so the USB bus
in computer does not need to try & support more load than it can.
Avoid charging an iPhone, iPad, etc from the computer, those little
USB chargers are better. And the Wacom tablet may be OK when
the computer is running on the power adapter.
The computer may not need a new logic board, but an adequate diagnosis
should be done before any major efforts are made into a big takeapart.
If you are in the USA or Canada, an Apple Store with Genius bar could
help determine the issues in the portable computer, if you check ahead &
set an appointment to discuss and diagnose this issue. This should be free
however the repair of any issue is another matter, and would cost. You can
take the unit anywhere qualified certified authorized trained Apple specialists
hang out, for further testing and repair. Or trust a reputable repair company
at a distance, and mail the computer away, after contacting them for details
on how they prefer to set up the repair, and how they want it shipped.
If you do get it repaired for one thing, while it is open consider items such as
a new larger capacity hard disk drive, etc. Otherwise a little while later, it may
be due for one, as they will fail. Even the fancy SSDs can fail quick enough.
Hopefully you can get USB to work good enough to further troubleshoot.
Good luck & happy computing!

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?

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.

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?

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!

Hi
does anyone know how to fix the message on my iMac:
"Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled."
This is a brand new machine and did not have anything attached to the USB ports"
Thanks for any help

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

HT1338 what to do when this happens 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, one or more of your USB devices have been disabled.

update to the above (my edit has disappeared !)
This appears to be a problem with the USB cable. I can make this message happen during a sync with itunes. If i lift the cable with my finger about a cm away from the join between the cable and the USB connector head of the cable I get this warning message each time I try. I must have a loose wire/connection in the cable.
Thanks

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

Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled. This shows up even when I am not connected to a USB. what do you think the problem is?

Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled. - This is what shows up sometimes even when no USB is connected. What could be the reason?

Try a different USB cord, seen this many many times, its highly likely a damaged USB cord.
Restart the computer to redefine Port definition. If still a problem
