Just recently, I keep receiving an error, every couple of minutes or so, thats states: "A USB device is currently drawing too much power. The hub to which it is attached to will be deactivated." Now I have seen this same problem posted, but I have No Device hooked up at all. I have a 2 year old macbook pro 2.4 GHz, running 10.5 I've tried rebooting but it continues to occur.

I get this strange message every so often, sometimes more often than other times. It says:
USB port drawing too much power. The device that is plugged into it will be deactivated.
There are only two things plugged into the USB-The keyboard and mouse. When I get this message, the mouse freezes. If I jiggle the mouse cable where it is plugged into the USB, it comes back and everything is fine until this message comes up again.
I have Macbook Pro Early 2011. recently my USB device stops working and I am getting message " The USB device drawing too much power has been disabled"and MacBook Pro getting over heated.

i just recently got a keyboard i had back and plugged it in with a mouse i typically use all the time. when the keyboard was plugged in i got the typical message for "USB device drawing too much power, has been disabled…" i just want to re enable the mouse. it was quite obvious it was the combination of BOTH devices that caused this, but i'd really like to just get the mouse working again. I've Tried Resetting the SMC and ran the diagnostic but nothing has worked.

This is my first post on the forums, although I'm planning on looking around in here once in a while, to see what people are posting.
For starters, I just wanted to tell you about this little problem I've been having with my MacBook 1,83GHz.
Sitting at my desk at work one morning, peacefully drinking my coffee, I suddenly received a rather discomforting error-message from my shiny new (about 1 month old) MacBook;
"A USB devise is currently drawing too much power and the port will be deactivated.".
Whilst working on my iMac as per normal, I get this little window that pops up declaring that a USB decice is drawing too much power from my computer and as as a result, one or more of my USB devices has been disabled.
This is not an alien dialogue box to me, I have seen it many times. The problem this time is that, when I removed all my devices to see which one was causing the message to pop up, I discovered that it was my keyboard that was misbehaving.
When the message pops up it states that the offending device has been disabled. This cannot be the case however, as I am able to press enter to close it, and if the keyboard truly is the problem then I shouldn't be able to close it with enter because it would have been disabled... right?
Wondering if anyone else has had this problem. My keyboard is the standard wired + number pad one shipped free with new iMacs. It's not a custom one, it's apple stock through and through.
The baffling thing is that this has only just occured. In the year or two since I bought my iMac it's never been a problem.
Yes I have tried using a different USB slot, and no that doesn't fix it.
This box keeps popping up unless I disconnect my keyboard which of course is no way to use the computer, and I don't have a spare keyboard handy.

i currently traded in an old macbook and gave my mom my imac. I bought a new mac pro but there is an issue with find my mac. i disabled find my mac on the imac and the macbook was wiped by bestbuy. however, both computers still show up on my find my mac app. it's not a huge deal but it's just annoying seeing 2 devices in there that will never actually be found.

Well, I just recently received a used wired apple keyboard, but whenever I try to plug it into any USB port, I get the following error: Even when I unplug every other USB device, I get this error. I'm using a Mac Mini.
View 8 Replies View RelatedTonight I've been transfering all my files over from my old MacBook and everytime I try to connect my IPhone 3GS by USB to my Mac a message comes up straight away saying "A device conected to your computer is drawing too much power, apple has disconected this device to prevent damage occuring to your computer"
I have tried to connect my phone numerous times while it has been conected to the power cord and also running on battery.
It also took my new Mac a good half an hour to recognise my external hard drive was connected and let me use it..
I have had this problem once or twice with the same IPhone and my old mac so im thinking it may be a problem with my phone considering it is 2 years old now?
But then again, my old mac that is nearly 4 can still connect to my phone when my new MBP can't.

I have a total of 10 USB devices connected to my G5 Mac, including hubs, printers and scanners. Most behave fine, but one or two cause minor problems. The worst offender is a Sierra Wireless 875U Aircard, which is a wireless broadband modem I got through AT&T. I use it for my Internet connection.
Every time I power up my Mac or bring it out of sleep, it won't recognize the 875U, even though it's plugged directly into the Mac's front panel USB port. I can't even see it on System Profiler. Having it in a different port or going to a hub port doesn't make any difference.
To make it work, I have to unplug it, wait a few seconds and plug it back in. My Mac then recognizes it and it works fine until I shut down the Mac or put it to sleep again. Granted, this is only a nuisance level problem, but it would be nice if the Mac recognized all the ports all the time. I'm running a duel G5 2.0 GHz under Mac OS 10.4.10. I see the exact same problem in my G4 iBook (1.0 GHz) also running Mac OS 10.4.10.

I hope the following problem is not too long winded. we have 3 identical Dual 1.8Ghz G5 Power Macs all with 30" Apple LCD screens, when any usb storage device is connected powered or unpowered, memory stick or hard drive, any pictures copied over to the mac are corrupt (lines through them, half the picture sheared off to the left or right, half the pic in another colour etc). f i connect the device to one of our older G4 machines or one of our new imac's there is no problem.

This is a problem that's been bugging me now for a while: when I plug in my iPhone or even a measly Usb Flash drive into my Apple Keyboard's USB port, a message appears on my Mac's screen saying: "A USB device can't draw enough power to operate properly. If the device came with a power cord, plug it into an electrical outlet. Otherwise, connect the device to a USB port on your computer." Does anyone know why the Apple Keyboard has a weird indented USB connector?

Everytime I plug the mic in it says, "USB device requires too much power." I just bought the mic. I tried calling the Blue mic costumer service but no one answers.

I was wondering if anyone knows of a fix for my iMac 21.5" which seems to disable the onboard sound upon restarting?
I understand that this can be remedied by resetting the SMC but I cannot be expected to do this each and every time the machine is restarted. Is there any way I can get it to work permanently?
Upon restarting the volume icon is greyed out, and pressing the volume up/down keys bring up the volume box with a "no entry" sign underneath the icon. I've tried unplugging and replugging the external speakers to no avail, and this occurs with the internal speakers also. I've checked the correct device is selected in the volume settings and the optical output is not switched on.
