So when I plugin in my iPhone 5 this message pops up? And don't say it's because my computer is unplugged because it is plugged in and charging right now!

Tried it in my Macbook Air and did the same thing, then used my car charger and worked fine! Thank you, but what is the worst the cord could do to my computer?

When I plug in my iPhone to my iMac my computer flashes a box that says my USB device is drawing too much power from my computer and claims one or more of my devices have been disabled. Then it will not sync my iPhone. Any solution ideas?

Try unplugging any other USB devices. If you are using a hub, don't, connect the phone directly to a computer USB port.
None of these are necessarily things you should do, but might help. For instance, if you plug the phone to an already busy hub, the phone might be "the straw that broke the camel's back" and lock out the hub.

I don't have anything else plugged into my MBP, so I am confused as to what's going on. This problem has never happened before. MBP is less than a year old - about 9 months old. HELP

Get a powered USB hub.

The rest of the message in the pop up window says "To prevent damaging your computer, the USB device drawing too much power has been disabled. Other devices may have also been disabled. When you disconnect the device drawing too much power, your other USB devices will be enabled again."

If you just bought the iMac and the Sjuperdrive take the superdrive back and get a refund. The by any other brand external DVD drive that connects by USB and try that. Most come with a Y USB cable to allow you to connect to 2 USB ports to supply enogh power to the drive IF Needed.
Or take both back and get a refund on both, you have 14 days to return it no questions asked, and buy another iMac and some other brand external DVD drive.

Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled. - This is what shows up sometimes even when no USB is connected. What could be the reason?

Try a different USB cord, seen this many many times, its highly likely a damaged USB cord.
Restart the computer to redefine Port definition. If still a problem

Sometimes you have to reset the SMC two or three times for it to work, don't know why. I've seen that error message before and 100% of the time it was fixed with an SMC reset. I suppose it's possible that your keyboard or mouse IS drawing too much power, do you have access to another you could try?

Check to see if you have a bad cable. After rebooting, connect a new one and see if it works.

I had the same problem with mine when I connect the ipod when it's full charged and turn on. The problem never happen when the ipod is charging or i'ts full charged and it's turn off. So just turn off your ipod down and connect to your mac again.

I've bought a new USB flash memory. I plugged it in the USB port then a message come out: Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled.... Please help...

I don't know what to do. I plugged that USB in both ports but the same message came out. I charged my laptop and the same thing happened again. The surprising thing is that I tried plugging the USB in my cousins laptop (Macbook Pro) and it worked!!! but not with mine. The USB flash memory made by PNY. Please help...

There are two types of USB 2 devices - low power which consume 100 milliamperes or less from the USB bus and high power which consume up to 500 milliamperes. Your flash drive is probably a high power device and is overloading the USB bus of your computer. (Some notebooks can support only low power USB devices.)
I know that my MBP's USB ports support high power devices but I've come across reports that not all high power devices will work on the MBA and that might be the case for your flash drive. My guess is it has a large capacity? 32GB or more?

When I plug my iPhone 5c into my Macbook an error message will come up saying "Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled" and it won't charge or sync

I have had my iPhone since November and have never had this problem with it before. Sometimes if I unplug it and plug it back in it will begin to charge. Other times it will just be sitting there, not touched and keep switching between charging and not. I have tried it with my Macbook plugged in as well and this does not change anything. Does anyone know how to fix this problem?

HT1338 what to do when this happens Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled.

Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled.

update to the above (my edit has disappeared !)
This appears to be a problem with the USB cable. I can make this message happen during a sync with itunes. If i lift the cable with my finger about a cm away from the join between the cable and the USB connector head of the cable I get this warning message each time I try. I must have a loose wire/connection in the cable.
Thanks

Everytime i plug in my USB for my android, i get the message that the device is drawing too much power from my computer. i just want to download my pics.

Everytime I plug in my android USB, I get a message that states the USB device is drawing too much power from my computer. The only other USB device connected to computer is my printer. Even when I disconnected the printer, I was still unable to use the android. When i use a non-android USB to say charge my phone, it will charge it, but it won't recognize any of my android data. What gives?

I'm going to guess that you are plugging into either the USB port on your keyboard or an unpowered hub. USB has two both low power and high power port specifications that determine how much electricity the port can supply to a device. The ports on back of your iMac are high power, the keyboard ports are low power. If you have an unpowered hub it has to 'share' power with all the devices you plug into so it too would have low power ports.

Would anyone know why my macbook says "USB device is drawing to much power" when I have my iPhone 4 plugged in?

When I have my phone plugged into either one of my USB ports, my computer sometimes will say "USB device is drawing to much power, to prevent damage the ports been disabled until the device is unplugged" or something along those lines...i was just wondering if anyone knew why...it does it to both ports.
Thanks

The first time it happened my cooling mat was plugged in, but its still been doing it even though it isnt anymore.
