the USB device drawing too much power has been disabled.

FYI, what you did was (a) dangerous) and (b) unforgivable on the part of D.Link.

You plugged a cable carrying 110 or 220 volts into a socket designed for 5 or 10 volts. You're lucky you're OK.

I don't know where in the world you are but I would report this dangerously poor design to the relevant authorities.

Don't buy D.Link again, and never change cords unless they are just a piece of wire, no wallwart.

I simply don't understand what could be going wrong.

I have tried all of the resets and even completely reinstalled my OS after wiping my computer. However, it has to be some kind of software issue. I plugged in my external speakers into one of my usbs and it worked. The other one isn't working. And when I plug in my mouse, I get nothing.

What in the world?!? I need my usb ports to make music this week!

Hi Guys,

I have read the entire thread but am unable to find a solution that would get my MBP's USB drives back again. The only thing that I connected to my USB drive was my iphone and that too with the original charger cable. This was 1 month ago. It gave me the "drawing too much power error" and has stopped working since then.

Now I have nothing connected to my USB drive. I have tried resetting the PRAM (or whateve its called) as recommended on this thread, tried removing all attachments, restarting, etc etc.. However nothing seems to work.

Now when I try and connect a 2GB/4GB or an 8GB "pen drive" (portable USB drive), it does not seem to work. I have even tried connecting an original apple keyboard, a mouse, iphone/ipod/ipad, yet nothing works.

I did a hardware test today. The test says all is in order.

Can someone recommend a solution apart from the ones mentioned here (and please dont say that I need to take this to the apple store, coz I can figure that out for sure)

Thank you

I didn't find a definitive solution – it just eventually resolved itself. Have you tried disconnecting everything, shutting the Mac down, removing the battery, unplugging it from the wall and leaving it for a while rather than just re-starting? Worth a try (if you haven't already).

This JUST happened to me. I used my sisters cable and VIOLA lol. it worked.

My cable was also quite old and it had a twist in the plastic tubing so maybe that had something to do with it. I say just get another cable to use.

This problem is bizarre.

Basically - I have an audio interface connected via USB, then one day i get the message 'usb device disabled drawing to much power....'

So i tried a few different cables, and 1 cable worked fine.

Now all of a sudden, the problem is back - the cable that was working fine is now not working fine.

I've tried 8 USB leads, reset the SMC, reset PRAM, etc etc......

All the 8 USB leads i have work fine with other stuff, but as soon as i plug this audio interface in, it doesnt see it. The interface is fine because i've tried it in another computer.

I've lost a lot of faith in apple products over the last year or 2. It seems like theres always some sort of bug/problem. This will be the end of the line for me now. I just can't trust the quality or reliability of their products anymore.

Losing patience too a bit.

I guess the jury is still out, but both mavericks and ios7 have had some problems that I was used to with Apple back in the day but that we have been largely free of for many years now.

No statistic evidence really. But the rotating lock bug in ios7 and this one is something I am not used to seeing

on all my Apple stuff. Ah well, material world.

Yes, this was aggravating. It did finally shut down the port I have my keyboard plugged in to. The USB Port Hub worked for me. Buy one that has its own power source, of course. I plugged a hub with its own power source into one of my working USB ports and voila! No more error message. Thanks for that advice. I just bought a "Belkin" brand for @ $29.00. It has its own power source and seven USB ports. Again, thanks for the help.

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!!!

WRONG.

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

Hi,

I was having the same problem. Got really frustrated and connected my usb to lightning chord to another computer and the same error message popped up. Found out the problem was the usb to lightning chord! Threw away the chord and used another. Problem solved!!! Make sure you check the chord before taking it to the genius bar!

This just started happening to me when I upgraded my iPhone and my iPad to iOS 8.1 - there must be some connection. I tried it with several different chords. I think it is an iOS bug. Happens even when nothing is plugged in.
