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.
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.".
an error message comes up when i try to plug in my iphone. it says usb drawing to much power.....?

Tonight 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.

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.

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 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.

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?

View 4 Replies View RelatedI have a tough one regarding an iMac G5 ALS 17" 2Mhz I am fixing. First I want to point out that I am familiar with the innards of these ancient beasts as I have fixed a couple 1st gen iMac G5 as well as iSights and Duos.
When I plug in the cord in the PSU, the 1st diagnostic LED comes on but when trying to start the computer the second diagnostic LED comes briefly on and then goes off. Nothing else happens, no chimes, nothing. According to Apple KB this is the sign of a faulty PSU. Yet, I have tried replacing the PSU and I get the same result.
Now the weird part is that if I unhook the LCD cable the computer starts normally (it chimes) with the display off. What is most puzzling is that it will start with the inverter hooked up but the LCD display cable off but will not start with the inverter entirely taken off but with the LCD cable on. It seems that it is the LCD itself that prevent the computer from starting. I thought the inverter would draw current but not the LCD itself so it's probably something else.
Anybody had anything similar happen to them? Could it be that the inverter is faly but it only draws when the LCD is hooked? Could it be some kind of short in the LCD or something that make it draw even with the inverter unhooked?
