USB Port Shut off

At least three times over the last several days, I've encountered a frozen cursor, after the computer has been sitting idle for a while. Neither my external mouse nor keyboard function, otherwise the computer seems to work ok. I assume that this is caused by a non-functioning USB port. Only way to clear the problem is to restart, which I have to do from the power button on the MacBook. How do I fix this problem? I've turned on the Console so I can capture the event associated with this problem. If I capture this event, what is the Apple address to send it to?

Perhaps you can figure out a good course of action after reading this: [MacBook Service: Frequently Asked Questions|http://www.apple.com/support/macbook/service>

  • USB Port shutting down...

    Anytime I plug in my Blackberry Storm to my USB port it gives me an error that it is drawing too much power and the port will be shut off...
    Why is this? I have had the phone for nearly a year and just now it is giving me an issue.
    Recently I upgraded my ram to 4gb, my HD to a 500gb 7200rpm drive. and updated the OS on my blackberry. Could any of this cause an issue?

    did you do the drive yourself? not saying you are not capable... the hard drives on these models are not very user friendly to install yourself. apple recommends a service provider do this for you...
    if you are fairly handy, mistakes can happen tho, something may have been messed with during the process.
    also, are you getting this on both ports? if so, how did you re-install OS X - o9r migrate to the new drive?
    are any other bb users complaining about usb issues with the new BB OS?
    Things to try: use the USB port towards the front, reload the OS on the phone, try a different cable, a powered usb hub, reinstall OS X from scratch.

  • K8N Neo Platinum USB ports turning off?

    Hi there,
    I've had a K8N Neo Platinum board (in an ANTEC Sonata case, Athlon64 3200+) for a quite a while now and it recently developed a troubling new problem.  Every now and then, the all of theUSB ports will simply shut off, dropping whatever devices happened to be connected to them.  I have a USB keyboard and mouse, so this is a bit of a problem...   If I connect a PS2 keyboard, I get a keyboard back, but it's not a realistic compromise.  Also, once the ports have been dropped, trying to inspect them in Device Manager hangs the machine. 
    I've read through the forum and see other problems related to USB ports with this board, but nothing quite like this.  I have already performed the cable snip trick for the front USB ports on the Sonata case (quite a while ago in fact, and it worked nicely) and I've already gone in the devices and turned off the "Allow this device to be turned off to save power" option.  Any other ideas on what to check? 
    I recently added two new USB devices to the machine: an Apple USB Pro keyboard connected via a Geffen USB KVM, and the USB hub that's sitting inside my Dell 24" LCD.  I'm going to try disconnecting the Dell's USB hub to try and eliminate it as a problem, and if that doesn't do it, I'll try running with a PS/2 keyboard for a while. 
    Anyway, if anyone else has seen this problem, I would love some assistance in fixing it.
    Thanks,
    --ben

    AFAIK, there is no 1.B bios for the Neo Platinum (MS-7030), only for the Neo2?  Am I mistaken?

  • PowerNap Time Machine backup?  USB Data shuts off in sleep mode!

    So how is PowerNap supposed to do a Time Machine backup when USB is turned off in sleep mode?  Everything else seems to work, but when I wake my computer back up, I am greeted with a message that the external hard drive was removed improperly, and no backups were completed overnight.
    I'm using a MacBook Air Mid-2012 and a 2TB WD External HDD that uses it's own power supply.

    A USB drive should be fine.
    Right before going to bed, I duplicated a bunch of large files and then went to sleep with my USB hard drive plugged in. When I woke up I realized that Time Machine did back up about one hour after the computer was asleep.

  • K8NGM2-FID and USB ports when off state

    I have a light "problem" which seems to come from the mobo.
    I'm using an iMon Knob remote controller (http://www.soundgraph.com/pr/e_pr_3.asp?m1d=1&m2d=3).
    The receiver is connected in USB to the mobo.
    Under operation, it emits a blue light permanently and flickers for each key hit.
    The problem is that, when I shutdown my HTPC completely, the blue light remains lit.
    The manufacturer sent me this explanation:
    Quote
    KNOB led lights on when USB 5V is active. When system is off state, generally in most of M/B USB 5V is inactive , but in your system USB 5V is active.
    Please update your M/B BIOS to the latest version.
    Is it relative to a BIOS parameter (3.20) ?
    It does not occur on my other PC.
    Thank you.

    Deckard,
    It sounds like you have a BIOS Parameter set which keeps some juice in the USB Bus while your system is powered down. (Remember ATX Spec does not turn fully off like the old bATX used to.) It could be that you have Wake up on LAN, USB Keyboard settings with a Wake Setting, there are several options in the BIOS that can do this.
    I would start with the manual and go though the BIOS Settings.
    Take Care,
    Richard

  • USB Hub Shuts Off

    I keep getting the following message when connecting my iPod after enabling disk mode:
    "USB Over Current Notice
    A usb device is currently drawing too much power.
    The hub it is attached to will be deactivated."
    This prevents the iPod from being mounted at all, so I can't change the disk mode setting which I think is the culprit.
    Any ideas?
    Message was edited by: cclarke

    Depends on what's in there... if the issue occurs with multiple cables, though, it's possible there's an obstruction in the port. You could go to any electronics store and get one of those cans of compressed air, you might be able to use that to blow out whatever's in there. They're good for cleaning out keyboards and laptops and the like. I've seen them at WalMart, RadioShak, Best Buy, etc.

  • Shutting off port

    I have a USB hub which is plugged into Pci 6-7 ( not sure until I pull case apart), I am using the Deck keyboard which really has bright keypads and a mouse that has led lights. My problem is the lights on keyboard and mouse never shut off when the computer is off. Is there a way to have the ports shut off when the computer is off?
    Thanks for any help.

    Do you have I-Charger or Super-Charger loaded & enabled? Maybe a Power Option setting that keeps the ports enabled? Is the hub self powered?

  • USB ports no longer working after 10.4.7 update

    Hi, I ran the latest update (10.4.7) on my machine which is a G4 Quicksilver PowerPC. I have an Apple 17 inch flat screen display that has two USB ports attached. I had my keyboard plugged into one of the USB ports on my flat screen. After the update both USB ports on the flat panel no longer work! I can use the USB ports directly off the G4 itself and it works fine. Has anyone seen this issue? I guess I am stuck now until Apple decides to fix this?
    Thanks,
    Rob

    In my experience, the USB ports on the back of an Apple monitor can be re-enabled simply by unplugging and plugging back in the device in question. You might also check to see that the USB Monitor hub shows up in System Profiler. My Apple monitor USB ports experienced no changes in moving to 10.4.7.

  • TS2634 When I connect iPad to Macbook Pro through USB Port or even charge my iPad via the apple adapter, it has no response at all. I can only charge my iPad when I totally shut off the iPad. Pls advise.

  • IMac Retina shuts off USB ports when sleeping

    I have a new iMac Retina i7 with 32GB RAM running Yosemite. Approximately 60% percent of the time, when the iMac goes to sleep, it shuts off all of the USB ports. This includes dumping hard drives without properly ejecting them, as well as shutting off powered USB hubs. Switching the drives and hubs around to different ports does not help the problem, and it appears to be becoming more frequent. Any suggestions would be welcome.

    I too am having hub issues with my 5K iMac. I purchased an Amazon Basics hub, that never worked at all. I returned it and got one made by vantec. I have two external hard drives connected to it, and they always are recognized after sleep or restart. But other things get dropped, like my two printers. I seem to be able to resolve the dropped hub ports by ejecting my external hard drives and then unplugging the power to the hub, then reconnecting the power. When i do, all the indicator lights come on again, and things work.
    I am working with Vantec about this issue, they have been terrific by email, and they are offering to replace the hub. But now I am wondering if something more basic is wrong, like this SMC reset that has been mentioned in this thread. I was about to ask if that was hard to do, but I just looked at the link provided by Ralph, and doing it is easy-peasy. I will give this a try, and try to remember to report back.
    thanks, Peter

  • USB port use causes shut off

    Hi,
    My lemony Macbook Pro (4,1) which has had two Hard drives, a logic board and a keyboard replaced in it's slightly 3 plus years (AppleCare just ran out) is at it again. Now any time I use a usb device, after a few moments, the computer shuts off (sometimes it restarts on it's own). This happens with a printer, scanner or even a flash drive. It's a new behaviour as of yesterday. Am I screwed?
    FYI, after the second HD failure I got a Macbook Air with SSD because I travel a lot and figured it was too rough a lifestyle for the macbook pro, so now this computer doesn't get moved and is treated lovingly... it just hates me.

  • Anyway to bypass a broken USB port? I got an error saying that my USB device was drawing too much power and had to shut off.

    I have a macbook pro. I just upgraded to Mavericks last night hoping this would fix the problem, but it hasn't. I received this error message and now none of my USB ports are working. I researched some and people have told me to reset the nvram, yet it is still not working. I have seen Thunderport docks that include USB ports on them, but they cost around $200. Just seeing if there is some sort of adapter or clever way to get around this problem? I mainly use my USB port for a Wacom Tablet. I was thinking about replacing the logic board, but that would be my last option. also, when i plug my phone into one of the USB ports, it shows that it is charging my phone, but it doesnt show up on my computer.
    thank you!

    You may see if you can get a rise out of it by use of another reset...
    •Intel-based Macs: Resetting the System Management Controller (SMC)
    http://support.apple.com/kb/HT3964
    Generally when combined total of items plugged into USB bus, where
    ports are powered from one internal source, is too high, you'd get &
    use a USB powered hub. This has a power adapter, so the USB bus
    in computer does not need to try & support more load than it can.
    Avoid charging an iPhone, iPad, etc from the computer, those little
    USB chargers are better. And the Wacom tablet may be OK when
    the computer is running on the power adapter.
    The computer may not need a new logic board, but an adequate diagnosis
    should be done before any major efforts are made into a big takeapart.
    If you are in the USA or Canada, an Apple Store with Genius bar could
    help determine the issues in the portable computer, if you check ahead &
    set an appointment to discuss and diagnose this issue. This should be free
    however the repair of any issue is another matter, and would cost. You can
    take the unit anywhere qualified certified authorized trained Apple specialists
    hang out, for further testing and repair. Or trust a reputable repair company
    at a distance, and mail the computer away, after contacting them for details
    on how they prefer to set up the repair, and how they want it shipped.
    If you do get it repaired for one thing, while it is open consider items such as
    a new larger capacity hard disk drive, etc. Otherwise a little while later, it may
    be due for one, as they will fail. Even the fancy SSDs can fail quick enough.
    Hopefully you can get USB to work good enough to further troubleshoot.
    Good luck & happy computing!

  • HP Pavilion P6-2220t. All security USB connections are shut off in BIOS. Need to turn on.

    I was told that all of the Security USB connections was shut off in the BIOS. The only controls for this PC is USB ports for the mouse and keyboard control ect.  How can I get into the bios without the keyboard and mouse in operation? There is no other way to control this model computer. The only connections on this PC is USB connections only. Again If I can, somehow get get into the BIOS I can turn the Security USB connections on as they should be.

    Hi Big_Dave,Yes the ALL security USBs in the Bios are in fact shut off. I saw it done in front of me.The person was trying to install Windows 7  but the usbs in the bios stopped workingeach time he tried the install the software. He thought that shutting off the securityUSB in bios would stop the security only and allow windows to be installed. He thensaw that all the security USBs in bios had completely shut down the usb connectionscompletely. I didn't know that is what he actually done until he went through with meand told me everything that he had done step for step with me. Then it dawned onme that was in fact what I saw him do. Anyway the Security USBs are all shut off.Money is hard to come by here so it will remain disabled until someone can walk methrough getting it turned on somehow without working usb connections. I refurb.laptops but not PC desktops like this one. This is new to me also. I think I will stick torebuilding laptops after we figure out how to get into the back door or find a way tohelp[ him fix this problem if I can. Anyway thank you for your input into this problem.

  • Can you turn power off of the USB ports

    I have a powerbook g4 800 and it has an external fan that is powered by USB. When I put the computer to sleep and have the power adapter not plugged in, the fan still gets power. So I occasionally have the power completely drained after the laptop was in sleep. Usually I remember to shut off the fan, but it's an extra step that seems like it could be solved by setting something somewhere to power down USB on sleep.

    Unfortunately the Mac holds the USB ports in an active state to allow mice and keyboards to wake the machine - I don't know of any way to change this.
