Usb port 1.1 too low

our usb ports are 1.1. too low for ipod shuffle which needs 2.0 if we buy a dock or flexible dock, will both work for converting or will we still be in trouble? operating w/ OS x10.2.8

I'm confused, since Apple claims the shuffle will work on a USB 1.1 port using 10.2.8. (Transfers will obviously be slower.)
If your problem is that the ports accessible to you are low power, for which Apple's recommendation is a different operating system, I'd try a powered hub. The shuffle dock I'm familiar with is really an extension cable with a fancy end on it; to use it you'd want to make sure its male connector was plugged into a port which was providing enough power.
Good luck

I keep getting 'USB port is drawing too much power error'

I have an old 2010 13" MacBook Pro. Just tonight, it started giving me a 'USB port is drawing too much power' error. The only thing I had plugged in to my MacBook was my iPhone cable (without the phone) and an Intuos tablet I recently bought. At first I thought it was the tablet, because the tablet started acting wonky after that error message (it worked just fine earlier in the day).
After restarting, the tablet works with no problem so I thought the problem must be the iPhone cable. The thing is, I read in some other forum that a cable not plugged to the iPhone shouldn't draw power, and they said if it does then it's a sign for a short circuit. My iPhone cable is a little bit worse for wear, to be honest.
So my question is: Is the problem my cable and if it is is it dangerous if I use this cable to charge my phone with a USB wall charger? 2nd, Is there anyway to fix this other than buying a new iPhone cable?
Thanks in advance!

Thats a warning. if you continually get that warning with the iphone cable and you keep using it. You could eventually disable that USB port.

MacBook error "USB Port has drawn too much power"

Hi,
I recently found a external hard drive and accidentally forgot to switch the volt down on my power brick, and ended up with 24 volts charging up to my white macbook 2008. It immediately shut down and i could smell some smoke coming from the usb port where i plugged in my ext. HD. I pulled it out immediately and it saw no physical damage to the port. When i turned it on, i got this message
" 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."
I restarted my laptop again hoping it would go away but it kept popping up every time. I plugged in a mouse and it didn't turn on, so i plugged it in to the other usb port and it blinked for a moment and turned off, which i presumed it was being disabled. I did SMC my laptop but that didn't work and i could faintly distinct the smell from my usb port still. Did my USB port get burnt? How to i re-enable my USB port?

No, my apple charger came with my Macbook, the switchable power brick was for the hard drive.

I ve upgraded my MBP to SL and since 3/4 days ago i ve been experiencing problems whit the USB port. A nice "error window" pop up saying that one or few USB port is driving too energy and therefor will be shut down. The error continued to pop again many times, sometimes 5 of this windows pops up simultaneously. Yesterday i took a decision (a big step) and reset my mac (after trying other solutions and check ups such as reset the parameter random access memory (PRAM) and nonvolatile RAM (NVRAM) and hardware check ups). Been there done that. I ve decided to install first tiger and no error was shown, then i ve upgraded to leopard and again no error was shown... At last when i ve finally installed SL and reboot the system the first thing that showed up was was that nice error...At least this time it shouws up only at start up... I must conclude that there is a kind of bug in the SL system is there anyone that has an alternative solution to this annoying problem, apart from changing mac ....=D....?

Marco,
Just to let you know you are not alone. I have a similar problem with my MacBook but the message does not seem to affect operation. It occurs when I plug in my USB speakers, but the speakers work just fine and the message does not reappear unless I unplug them and plug them in again. I chatted with a specialist at an Apple store and it was suggested that I make an appointment with a "genius". Because it does not appear to affect operation, I am inclined to wait and see if 10.6.2 changes this behavior.

New MacBook, New ipod, "Usb port drawing too much power" message?

I just got a new MacBook and ipod Nano, and when I plugged the ipod into the usb 2.0 port, a message came up saying a usb port was drawing too much power and would be shut down. i'm charged and plugged in, is the wire messed up, the port, or the nano?

strange - try the second port.
possibly a bad cable.

Mini DisplayPort TOO LOW!!!!

Seriously? This major design flaw is making me so angry...
Check it out;
http://i36.tinypic.com/1zguolh.jpg
I bought a Mini DisplayPort to DVI adapter. I tried to put it in the back of my iMac but noticed after a lot of frustration that the whole port bay is too low. All the USB ports are ok (still fits the USB) but the Mini DisplayPort won't fit the cable!!!!
Please tell me there is some DIY fix for this because I JUST got my iMac back from repair (hard drive was failing) and do not feel for another 1 week repair. I do not have the time and patience for it.

There is no probable fix you can do yourself. It appears that the technician put it back together wrong. They need to make it right.

USB Ports Not Working Correctly

Firstly, apologies for posting this, I'm almost certain it would have been asked before but I just CANNOT get decent search results from this new support board.
I have two Mac Pro's and a MacBook Pro. I am trying to get a USB drive connected to one of the Mac Pro's in order to format it to use to for Time Machine on my parents iMac. Until recently the drive was being used to store my media for iTunes on Mac Pro 1, I now use a NAS drive for that. When I plugged the drive in to MP 1 it wasn't recognised on any port. I plugged it into MP 2 with the same result. It powers up, I can hear it spinning but the drive doesn't appear on the desktop or system profiler. I have an identical drive (Freecom 400GB) and plugged that in with the same result - not recognised. However, when I plug either into my MBP they are recognised instantly. I tried plugging my USB card reader into the MP's, the card is recognised but I get an error claiming that it has been removed after a few minutes.
Have both my MP's got bad USB? Anyone else had this problem? How can I troubleshoot it and cure it?

One frequent problem with USB-powered devices is Power.
The keyboard-mounted USB port is not available for ANY expansion devices, however small their power requirements. The keyboard and a low-power Apple mouse use ALL available power. The second port is a convenience so that you can plug in the mouse on either the left or the right -- but not both. Devices plugged into the keyboard will not be reliable, and may affect keyboard and mouse operation as well.
In the Mac Pro, there is a per-cable power budget of 500 mAmps, but there is also a shared budget of a certain amount in total for ALL front USB ports, and a different budget in total for ALL rear USB ports. Putting too many devices (drawing too much power) on either the front ports or the rear ports can cause them to go flaky without giving error messages.
So my question would be, "What else are you running through the front or rear ports at the same time? Can you plug your test device into the front ports as the ONLY device or the back ports as the ONLY device to check it out?
EDIT: Another problem is "free" cables that come with some devices. They seem to be free of good connections and good current-carrying capacity as well. Don't give up until you have tried a different cable, preferably USB2 certified.

USB ports going loose.......

Hi,
I have a 2 months old USB modem which i use to connect to internet. I have an HP netbook(1 month old) and a Samsung laptop(2 months old) on which i use the USB modem.
Now this USB modem Huawei EC150 has an issue, it fits a bit tightely in the USB ports and takes a little extra effort to plug it in. After two months of usage it has loosened up the USB ports on both of my new laptops. Now the USB modem plugs in easily on both the machines but the ports have become bit too loose for other devices.
Now i am wondering if this will eventually cause the USB ports to become too loose and cause other devices to dangle too much and cause loose connections to the computer.
As of now this is not too much of an issue cause i have not had loose connections with other devices except for an old pen drive.
If this can be an issue in future, is there an easy way to fix this? Or will i have to just visit the service centres to get the ports replaced. I read on some forum that we can bend the small clips or notches (whatever you would call them) inside the USB connectors on laptops to make them tighter again. Maybe i am just bothering too much about my new laptops.
I suppose its the USB modem that is the culprit here, have never had such an issue with any USB device on my old desktop that i don't have with me now..
Please help...........

I think its the whole socket, connector looks fine and connect well but i can move it up-down and left-right about 3mm
Edit: went to the retailer and tried a new controller, same *problem*

Mac pro usb ports won't work when ipod is plugged in

I just bought a used Mac Pro (2008). 8 cores, 12 meg 0f ram, all of this so I wouldnt be limited as I was with my 4 meg Imac. I go to plug in my ipod, and none of the other ports work, I can't use the mouse or keyboard. Is there any way around this. I had to plug the ipod directly into the tower (the port wouldnt work) This is frustrating, I get this model to be more than capable for what I need, and something like this pops up...always something. If anyone out there has had this experience, and figured out a work around, please help. Thanks

okay, that doesn't sound usual. Sounds to me like the usb port is drawing too much power. Try doing a repair permission or SMC reset. If you are using it with a USB hub, maybe that needs plugging in to the wall, or maybe it has gone bad. I can't help you a lot, but just a little bit. repairing permissions is through Disk Utility. SMC goes like this: shut down the Mac pro, unplug the power cord, wait 15-20 seconds. reattach power cord, wait about 15 seconds, then press power button. you can maybe try resetting the PRAM-shut down Mac, turn on computer, hold down Command, Option,P and R keys before grey screen appears. Hold down until computer restarts again and you hear the 2nd startup sound. Let go of the keys. You can also check in "About this mac" (more info) to see if there's something wrong with the USB ports themselves.
Other than that, could be logic board battery. Maybe Archive and install. Sorry, the crystal ball has gone dark. I"m sure someone else can enlighten you more than I can. I always plugged my ipod directly into my tower via the front USB port...

Dead USB port running hot

I have a mid-2010 white unibody MacBook. It's been running fine, with the exception of a problem with the dashboard after the most recent firmware upgrade about a year ago. I just learned to work around it. But then Friday I got an error saying the the USB port was drawing too much power and was shut down. Sudden and random, as it had never happened before and showed up as I woke it up from screensaver mode. Nothing was plugged in. I have a Magic Trackpad and a Logitech keyboard connected via Bluetooth. Disconnecting them doesn't affect the error. I've tried rebooting and resetting PRAM & SMC. I'm trying to reinstall Lion, but I don't think it's a clean or fresh install. Has anyone encountered a USB port that dies but runs hot? The CPU seems to run a lot warmer than usual, buy about 20° F.
Any help is appreciated!

Take a look at this discussion:
https://discussions.apple.com/message/22922870#22922870
I recommend you make an appointment at an Apple genius bar and take the Mac in for a free diagnosis.

MacBook(2009) disables USB ports!

I use a cooling pad for my 2009 macbook. All of a sudden now when I plug it in to my USB port it tells me the USB port is drawing too much power and it disabled it. (btw: I have it charging and it's at 99%)

The built in USB ports can only supply a limited amount of power. Try to draw any more than that and the Macbook protects itself by turning the ports off.
The way around this problem is to use a self powered USB hub.
You plug the hub into a wall outlet for power, and connect it to the Macbook with a USB cable for data. All your USB devices can now be plugged into the hub, and whatever power they need will be supplied by the hub not the Mac.
Examples of powered USB hubs:

Clicking iMac and Failing USB Ports

Hey. I've had my new iMac G5, 18.ghz for about a month now. I'm new to abll ebut I love it until a few days ago. My iMac every few minutes or so makes a click and then just keeps going. It's a sound from the computer and not the speakers. Also yesterday my lowest USB port at the back of my computer failed and nothhing i plugged into it would work. I ran a hardware test and everything came back saing it was fine. I restarted and all my USB ports were not working! I resttarted again and now everything is fine. Has anyone else had hte same problem?

The keyboard USB port is USB not USB 2 and doesn't have a lot of power. The back ports are USB 2.0 and have more power.
If the USB ports are drawing too much current they will shutdown and there should be a note in the log telling you so.
Open the 'Utilities' folder and then run Console and look at the time it happened and see if its there or not.
If they shut down restarting is probably resetting them.
Well if its the side opposite the CD slot then I'd think hard drive. Run disk utility and see what it says under 'SMART status' It should say 'Verified'
Does it lag when its making the 'Click'? and is it aloud click or more like regular drive activity all of a sudden?
as StevenC said its probably a good idea to back up any data you have.

HELP ! My USB ports seems to be deads !

Hello,
For my weekly back-up, I use an USB external HDD that have to use 2 USB ports.
In order to use only 1 port, I've connected my external HDD to a power supply.
Unfortunately, it seems that the power suplly I used wasn't the goos one for my HDD and when I've connected the HDD to the MacBook, the MacBook as turned off. So, I quickly have unplugged the USB and I've reboot the MacBook but it told me that the USB port was using to much energy and that it will be disabled.
So, I've unplugged all the rest on the USB (my keyboard with my mouse plugged-on) and I've reboot the MacBook. Unfortunately, it told me again that the USB port was using too much energy.
So, I turned off the MacBook, unplugged the power supply and removed the battery and I plugged my mouse to the 2 USB ports in order to unload a possible capacitor too much loaded and I turned my MacBook back on.
Now, I don't have any message but the 2 USB ports are not working. Here is a capture of my System Informations :
http://dl.dropbox.com/u/331131/info_sys.png
I searched how to activate my ports on the Internet but the only solution I found was to reboot the laptop, and it's not working for me...
Do you know how to activate manually the USB ports or do I have to make my mourning ?
Thanks,
-Pit

Bonjour,
Pour mon back-up hebdomadaire, j'utilise un disque dur externe en USB.
Malheureusement, celui-ci m'oblige à le branché sur les 2 ports USB de mon MacBook, ce qui fait que c'est assez chiant de bosser dessus pendant que le disque dur est branché.
J'ai remarqué que mon boîtier de disque dur avait une prise pour alimentation externe. J'ai donc branché la première alimentation qui m'est tombée sous la main et qui semblait être faite pour lui. Comme ça, j'avais l'intention de ne brancher le boîtier qu'à un seul port USB et ça aurait dû fonctionner...
Sauf que voilà, de toute évidence, l'alimentation utilisée n'était pas la bonne et lorsque j'ai branché le boîtier, le MacBook s'est éteint.
Je me suis empressé de le débranché et j'ai redémarré le MacBook.
Au démarrage, celui-ci me dit qu'un port USB consomme trop d'énergie et qu'il sera désactivé. Et effectivement, il l'est. Je redémarre donc en débranchant tout ce qu'i y a sur les ports USB (mon clavier et la souris qui est branchée dessus) et je redémarre. Rebelotte, le même message qui revient. Je l'éteint donc, le débranche, enlève la batterie, branche ma souris en USB pour "décharger" un éventuel condensateur trop chargé et je relance la bécane avec la batterie et l'alimentation.
J'ai plus le message, donc j'ai un peu d'espoir qui revient et je rebranche ma souris pour tester le port... rien.
Je redémarre, re-test... rien.
Je vais dans les informations système, et j'ai ça :
http://dl.dropbox.com/u/331131/info_sys.png
J'ai cherché comment ré-activer mes ports USB mais la seule solution que j'ai trouvée c'est de redémarrer la machine, ce qui ne marche pas dans mon cas.
Avez-vous une solution pour ré-activer mes ports ou dois-je faire mon deuil ?
Merci.
-Pit

Try to reset the parameter random access memory (PRAM) and nonvolatile RAM (NVRAM) on your computer. Turn off your computer, then restart it and immediately press and hold the "Command," "Option," "P" and "R" keys on the keyboard. Release the keys after you hear the startup chime for the third time and your computer should boot normally.
To avoid such issues you may use a self-powered USB hub (one that comes with a separate power brick).

KT4VL USB Ports

I have had 2 KT4VL motherboards where the top 2 USB ports nearest the PS2 ports have stopped working. I sent the first motherboard back and it was found faulty and replaced with the exact same model. Again, after a few days, the very same 2 USB ports on the new board broke in exactly the same fashion. I have sent the motherboard back but the place I bought it from say they can't find a fault. How can this be when the faults are identical, one being found the first time and not the second?
I am using WindowsXP Pro but they are testing the board with Windows 98. Will this make any difference?
Thanks.

my usb ports are screwy too. my webcam works sometimes and doesn't other times. seems if i have all 6 ports used then it doesn't work but with only 5 used it works. i also have two kbs plugged in and both are 2 port usb hubs as well so that might be affecting it. also, when i have my printer turned on and plugged in my kb doesn't work in dos or to get into bios. i have to have the printer turned off. it's really weird and i don't know why. i also can't have both kbs plugged in when i want to get to bios.
these are just some examples of the weirdness on my comp. some of the problems are probably the mobo and some are probably windows. i find that if i leave one kb alone in the top ports then most of my issues go away except if i use all 6 ports.

My laptop macbook pro has a problem with usb port they are not working.
