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

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

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!

"Because a USB device was drawing too much power from your computer..." error withOUT any USB device

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:

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.

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?

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

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
You can also resetting PRAM/NVRAM: http://support.apple.com/kb/ht1379

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

Check to see if you have a bad cable. After rebooting, connect a new one and see if it works.
