    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...

    So was the iPod touch plugged into the Belkin charger or the iMac?

    What was plugged into the Belkin charger at the time?  (when I think charger, I think power adapter)

    What was plugged into the iMac to prompt the message?

    Either way, of course stop using the Belkin charger and make sure everything else works.  Does a different charger work?

    I had a similar problem with my MacBook Pro Retina 15" & my iMac showing that my iPhone 5 was drawing too much power and the sync was not possible.

     

    I pulled out all my original and non-oem data cables and started testing one after the other and i found out that the issue did not araise when i was using a Genuine Apple Data Cable.

     

    The Genuine Data cables allowed me to Charge & Sync with my Apple computer while the NonOEM allowed me only to charge.

     

    So i marked/coded my original data cables for the sync and the non oem for charging.

    I now make sure that the non oem data cables are charging from a USB outlet that gives only only a 1.1amp or 0.5 amp to protect my iPhone battery on the long run.

     

    I understand that Apple must have put in some kind of a chip on the original data cables to make you buy the genuine ones.

    I hope this post helps everyone facing similar problems.

    It can happen without any USB cables attached at all.

    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.

    Use the Apple charger instead of the Belkin, call Belkin to deal with the smoking Belkin charger, their customer support number is 800-223-5546

    I do not think that it can happen without any devices drawing power from the machine.

     

    Logically speaking..If that happens it must either be a software problem or a hardware issue.

     

    I once had a refurbished HP Pavillion DV6Z (Z=AMD & T=Intel) machine whose power charging light would switch on without the power cable being connected to it in the middle of night!!.

    It was very scary, i called up HP and they changed the motherboard.

     

    Hope that helped...Thanks.

    It even happens on Hackintoshes (suggesting it's a software problem):

    I've had it on two different Mac Minis, even with no USB devices attached. Turning off and unplugging for a few minutes before re-starting sometimes fixes it but there's no common cause. Hasn't happened to me for a few months, though.

    "I do not think that it can happen without any devices drawing power from the machine."

     

    Well I can assure you that it does. See, for instance, my post on 07-Mar-2013 09:16.

    No USB devices connected never happens, this is a report from an MBP with nothing plugged into the USB ports, but there are still 4 USB devices 'connected' (as you can see from the report)

    Any one of those can be defective and that could cause high current drain from the USB bus.

    Hi, Frankly some of those accessories out in the market may be compatible with Mac but may not be optimised with a Mac and will land U in lots of trouble.

     

    Apple has the best customer support programs in the industry.

    Call the Apple helpline, if ur problem is caused due to a manufacturing defect/malfunction and ur product is under warranty they will repair or replace your item free of cost.

     

    I advice that you buy the legendary Apple Care for all your Apple products.It is so much peace of mind and reassurance for a little more.

    Oh really? Are you saying I have been dreaming this usb message for almost a couple of years now every morning when I turn on my imac? I have different operating systems on various hard drives attached by firewire to the imac, no matter which one i startup on, i still get the message, WITHOUT any usb attached. Recently I installed a new hard drive with Lion - first start up I didn't see the message and I thought: hurray! Well, second startup it's back to the usual message on the screen. Luckily I only have to click it away once, it used to be many, many messages. I have gotten used to it, but my concern is: what if I want to sell the machine? Nobody will buy it :<

    Once again, that condition is impossible regardless of whether anything is plugged into the external USB connectors, read my previous post.

     

    Your iMac has a minimum of an iSight Camera, an IR receiver and an internal memory card reader, all of which are connected, and all of which are USB.

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