the USB device drawing too much power has been disabled.

external or internal: still an apple problem, isn't it? a problem the company is obviously sweeping underneath the carpet.

I would appreciate some help from Apple even if I am out of warranty. Thanks.

This is an Apple users forum, it is not Apple. Take your MBP to an Apple Store.

Its a bad power cord. Switch cords and all works great!

I think you mean "It's a bad USB cord."

Swapping USB cords did the trick for me! What an odd situation.

im getting this problem ever since i plugged in a d link hub now no usb is working and the curser keeps freezing every couple of seconds help?? tried every solution ats next

are your usbs working? found out my problem fried logic board due to power surge fkin joke has to be replaced costing 650! crazy and no choice but to go ahead with it

I doubt that your logic board was fried by a peripheral device, especially one connected via USB.

How do you know what happened, or is this just a guess?

What is this hub that can destroy a Mac by using the wrong cord, and which cord, AC or USB?

it was a D-link powered usb hub i used wrong AC, i also had a ex hardrive plugged in to hub now no more good another 100 quid!

Did it have an external transformer (wallwart) and you replaced that cord with a standard cord?

ya i lost it and found which i tought was it but turned out to be two powerfull i guess.

I had this problem yesterday on stage with a midi controller keyboard. Today through trial ad error i have locatd the problem to be with the usb cable and not hardware. Gig was fun though!

This happened to me today for the first time too. And the only hting I have plugged in is my iPhone as well. With the original cable. Very odd and would liek to have a real solution.

If your charger does do this, u can go to a genius bar and tell them that your charger has an error when you plug it in. and they shooulg give you a new one

Replace the cable with a new one. It worked for me.
