the USB device drawing too much power has been disabled.

I am a developer and had this problem when plugging an iphone or ipad mini directly to my macbook retina. I swapped cables and problem solved.

SO - problem is - bad apple lightning cable. I am swapping it out at the apple store today.

eskim023 is right.. it's a **** lightning-usb cable. freakin Apple was saying its a maleware on my phone or macbook and I should pay them 99 bucks to solve that.. *** em.. bunch of aho and sscammers.. not gettin money from innovation so now they want to scam us

See my earlier post two back - nothing to do with cables as none was plugged in. It then just stopped doing it for no apparent reason.

Today, though, it's back. And it's not even the same computer. It's now happening on my six-week-old Mac Mini (2.5GHz i5 running 10.8.3). First time it's shown up since I bought it, following a re-boot earlier today with no changes made to peripherals, cables or anything else.

And, incidentally, if the computer has disabled the devices allegedly 'drawing too much power' why does the warning still keep coming up when you close the window?

Like so:

Yes, I'm having this too. First my phone stopped charging in my car (Subaru). It would either not charge at all or it would begin charging and then stop. I switched white cords, using a cord that works on my computer, and that would not work. I just plugged the car white cord into my computer and got the same message. Time to switch back to the cord that works. Hmmmmm... Yes, phone charges. Yep, definitely seems to be the white cord. And I am getting the warning even when nothing is plugged in. Strange. To the store I go. Thanks for having this info here!

I'm getting this error when just plugging in a micro USB cable with nothing connected to the cable!

Try another cable, same result?

I posted here a year ago saying that I have this same problem even though no usb device was plugged in ( I also had followed every suggestion that had been made here, no change). It is still there a year later, and just has become a nuisance that I ignore the best I can every morning I start up the machine. I also had stated that it was an Apple problem, and all the advise by apple staff here was just a cover up - the apple staff then removed my post. Well, I was right, a year later customers are still coming in here, reporting the same problem. I still have the same problem too, no matter what hard drive I start up from and no usb device attached. I think the time has come that apple will have to step up to the plate and admit its shortcomings, and there are plenty, that were easy to cover up before because the public was on their side. BTW, I have been on the mac since the early 90ies, and I repeat itagain here, Apple has become a greedy company like the rest of them, ruling with an authoritarian fist. Now watch the apple police remove this post again.

I've read of the same problem in Hackintosh forums (e.g. Tonymacx86.com's) so it would appear to be a software issue rather than a hardware one.

I fixed it for now by turning my Mac off, removing all USB cables, unplugging it then leaving it turned off for about ten minutes. Only after re-booting did I reconnect any of the USB cables and (so far) it's been OK for several days now.

No, it must just be that cable.

I got it without any USB cables attached at all.

Reboot

I've been getting the same issue for weeks now on my new 27' iMac (late 2012). Its driving me crazy, I've done all the resets and even an os x reboot. I constantly get the error with nothing plugged in. I've used different power cables and wall circuits to see if I could isolate anything causing the issue. I've brought my iMac to an authorized repair center and after they 'tested it hard' for 4 days they were somehow 'unable to recreate the issue'. So I brought it back home, booted it up and it instantly happened and has occured 100% of the times I've booted since. This is rediculous. Here is a video of it as well: http://vimeo.com/65979238

Our two year old was watching Dora on Netflix when my wife smelled something burning. She ran into the room to find the belkin charger smoking. It's the usb charger for wife's ipod touch 4th gen. The 20" imac had this same message on the monitor.

I read all the posts here, and i am still not sure if this is a bad cord issue or is it possible that the mac is spiking electricity?

I will try to call Apple, but if anyone has any good advice-- phone numbers, real people who are concerned, that would be good. The 2 year old could easily have burned himself or worse today.

Thank you for your help.

I fear the Standard Answer:

"Belkin, you say? You have reached Apple Computer, sir. We don't do Belkins."

Hopefully, the Next Step won't be attained:

"As a Post-Mother's-Day Special Treat, your warranty has been voided..."

Apple's so unpredictable these days...
