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

So have I .
This is occurring regularly on my 27" Mac. It doesn"t SEEM to be causing a problem, and I just switch it off. But the only thing I have plugged in is a USB keyboard.
I did have a hub, and an external hard drive but have removed these. Still getting the message.
I have switched off and disconnected from the socket etc. Still there.
Even when U had itenms plugged in, they all seemed to work OK.
I shall try getting a new cord to sync my i pad and i phone.

Acting on advice from another Communty, I did a "Safe" boot. I then did a restart. IT SEEMS TO HAVE WORKED. The problem has not recurred in the last month, and I have reconnected my external hard disc.

Yesterday on my PC on work (that I "Don't trust" on iPhone4) didn't want to charge my phone...same error as the rest of you...
Today, everything works!
A PC at work is a new, 4core i5 CPU, 8GB of RAM, 128GB SSD with USB2.1 & 3.0 working on Win7 SP1...what do say about that? Electricity? :/

Ok, let's retake this longlasting thread...
At work I am provided with a Dell Vostro model GodKnowsWhat desktop. Up front, discreetly hidden with a natty sliding lid you have a universal card reader, audio in and out via standard RCA jacks and six (6) USB ports. Great! Goody goody!! I'll be able to charge and use all my gadgets all at once!!!
Only the leftmost port will deign to charge (@500mA) any device. The rest are data only. Regardless of whatever is running in the box, Linux or Windoze.
So, I have glued a six outlet power strip on top of the Dell's case and have a spare iPad power brick in the drawer.

It happens on my hackintosh with mavericks too.
Oddly, the only way I got to fix that is to turn off the Mac, switch the main power button to Off, unplug the power cable, and then plug it in again, switch on, and restart.
The usb pop up message will disappear.
Maybe with an iMac you could simply shut down and unplug the power cable.
hope this helps
