How to fix: "One or more of your USB device drawing too much power..."

Plugged my iPhone to do my usual download of photos off my phone into my iPhoto library so that I can edit them and post on eBay and Etsy. Suddenly, I'm getting 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'm surmising that it's because my USB cord (connected from my iPhone to MacBook Pro) might be damaged. It's not charging correctly. Keeps going on and off when plugged into wall or computer.
So, will buying a new cord this solve the issue? I have to get one anyway so I guess I'll find out!
Meanwhile, for tonight I'll have to do just email the photos to myself. Ugh.

It should fix it. I would unplug all of your other USB devices from the computer and see if it continues with that error. If so, then certainly replace that cord (do it anyway since its having issues even in the wall)

"Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled.

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??

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

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

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?

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

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!

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.

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.

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

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

When I plug my iPhone 5c into my Macbook an error message will come up saying "Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled" and it won't charge or sync

I have had my iPhone since November and have never had this problem with it before. Sometimes if I unplug it and plug it back in it will begin to charge. Other times it will just be sitting there, not touched and keep switching between charging and not. I have tried it with my Macbook plugged in as well and this does not change anything. Does anyone know how to fix this problem?

Might want to have your MacBook looked at.
