Disconnecting USB devices

Hey guys,
i have problem with all my USB devices with memory (external HDDs, lumia phone etc. devices without memory like mouse works fine), they just randomly disconnects - no matter what USB port i use. Sometimes right after i plug them in, then they reconnect after few seconds, then disconnect again and so on. Sometimes they stay connected for a while, then disconnects. I am mostly able to copy what i need, but its very disturbing. Anyone have idea, what could be wrong?
I bought notebook without OS - i got original windows 8 Pro 64-bit with 8.1 update. There was no USB driver delivered on driver CD, windows just downloaded some. And there are none on msi web.

Make sure you installed intel chipset drivers since some times USB host controller driver is in that pack such USB 3.0 controller and so

  • How to stop/disconnect USB device on OSX?

    How do I manually stop a USB device that I don't want the OS to recognize or run?
    On "About this Mac > More info" page, my Dell Axim X51v Pocket PC is listed as a USB device. I'm having problems using the Parallel Desktop running Windows XP to sync to the Axim because Parallel reports that "USB device you are trying to connect to the virtual machine is being sed by another process." Wait 5-10 seconds, then try to connect the device again. If this does not help, find the application that blocked up the device and disconnect it manually."
    AFAIK, nothing on my Mac is using the Axim right now, I have even disabled "Missing sync for Windows Mobile" and stopped it from loading so it must be the Mac OS not releasing the USB link so my Windows XP within Parallel is not able to pick up the Axim right now.
    In Windows, there's a "Remove Hardware" option. But I can't find this on OSX after digging around for half an hour, I think I'll get much better advice here, so I really look forward to your help.

    You wrote: "But I don't see the device as "mounted" on the desktop, or in Finder."1. In the Finder > Preferences > General tab, is the "Show on Desktop" option for CDs, DVDs, and iPods selected? If not, select that option and see if it appears on the desktop.
    2. Is it shown in the Finder Siderbar?
    Good luck!

  • Mac Pro randomly disconnecting USB devices

    Hello All,
    Am hoping someone out there will be able to advise me. I have a 1TB external SATA drive connected directly to one of my Mac Pro USB ports, (that is, not via a USB hub). The Mac Pro has a habit of randomly disconnecting the drive during file transfers. It seems to particularly do it when the screen saver initiates itself. I've disabled the screen saver but unfortunately that hasn't resolved the problem. The problem itself doesn't seem to be isolated to the external USB hard drive either. The Mac has on occasions disconnected other USB devices too.
    Any suggestions or ideas on what the cause of it is and how I resolve it?
    Many thanks
    GPJ007

    Yes Grant, I've exchanged the power suppply, cables, the HUB and also the HDD and checked them on my MBP - they work fine. The only USB slot that's working fine is the one on the PCI-E Card. All internal Ports do eject the USB HDD's and also have problem with Printercommunication. I can mount the USB HDD without Problem, until I want to access a larger File or transfer data from or to it, then it ejects itself - well after freezing the Computer for 5min first, until the unmount message appear.
    By the way: Sorry, was a bit frustrated. I'm working as an Freelance Editor and really need to have a working USB. But the only thing I found were a huge amount of questions to the same problem, but no solution. And from apple side the only advice was to not use third party device or use only powered HDD's and HUB's. That's not really helpful...
    GPJ007:  Ok, I hoped to not have to make a new Setup of the OS and all the program. Well in a few weeks there is a gap in the order chain, I'm going to reinstall the OS then and let you know about sucess or not.
    Thanks in advance

  • Windows 7 not forgetting disconnected USB devices, only on one PC, but not others/difer OS

    Okay so I've got 3 computers:
    1. Asus M5A99X EVO MOBO, Windows 7 Ultimate 64bit
    2. Lenovo Ideapad u310 LAPTOP, Windows 8 (just 8)
    3. Asrock z87e-ITX MOBO, Windows 7 Ultimate 64 bit and Windows 8.1 Pro 64-bit
    This issue only happens on computer 3 under windows 7.
    I've got a KVM switch that's supposed to make switching between these computers easier, it's very basic, it has one USB port going into it, and I plug my keyboard into that, my keyboard has a USB port on it that I plug my mouse into.
    When I'm on windows 7 on computer 3 the KVM works fine for about the first 4-7 switches between it and another computer. But after that I get "USB Bandwidth Exceeded" popups. I can switch the port it's plugged into the computer and it will start
    working again, but that defeats the purpose of having a KVM. And today it even locked up while I was MANUALLY switching the cable between my computers front access ports, because obviously the KVM wasn't reliable (like I switched between computers once every
    4-10 minutes), and even BSOD on me.
    I've contacted both Asrock and the KVM manufacturer and they both say it's the other's fault.
    So I shrank my C: on Comp3 today and installed windows 8.1 on it, and than I spammed the KVM switching like 8+ times, and it never once locked up or complained about me exceeding the bandwidth.
    So that means it's now Windows 7's fault, but it doesn't do this for Comp1.
    Somehow my new computers Windows 7 is not working right, and I don't know any viable options I can do about it. (comp3 is only about 1-2 weeks old) I've ran all the windows updates I can and it no longer says there are new updates when i run it.
    So I need some help about finding out why my Comp3's Win7 isn't forgetting that a USB device is no longer attached, because Win8.1 seems to have no problem with it.
    And just sticking with Windows 8 isn't really the solution, as I can't %^#$#!@ stand Windows8/Metro/Tiles/tablet$@!#onmydesktop.
    (laptop is a work laptop and i have no choice, but it's modded so I have my start menu back, but still it's annoying anytime I accidentally leave my desktop.)

    ...because it happens with even just the keyboard.
    Even though it all works with Win8.1 have you:
    -Tried a different keyboard?
    -Tried connecting mouse and keyboard to an external powered hub and connecting the hub to the kvm?
    -Tried connecting kvm to powered hub?

  • USB not recognized - even when there's no USB device at all (Windows 7, Pavilion dv7)

    Since a few days now I get the message
    'The USB-device was not recognized: One of the USB-devices connected to this computer does not work correclty. The device has not been recognized'.
    It keeps popping up from my right corner below, every 5 seconds if I don't click it. When I click the message, I get a list of USB devices (ports) there are available. There's one 'Unknown device'. Maybe it has something to do with the finger scan (biometric)? This hasn't been working very good lately..
    Even when there's no single USB device installed (normally I have a mouse and a Targus laptop chill mat installed as USB devices), it keeps popping up. I tried deleting the USB port from the list (or uninstall it) in Device control, but it seems it keeps happening.
    I suddenly got it, I did nothing specific of did not connect any strange devices (except for a projector on the external monitor exit, but that has nothing to do with USB). I also hear the sound for connecting and disconnecting USB devics randomly when I'm on my laptop.
    Anyone has any idea?

  • MacBookPro - USB devices/HUB  question... thank you

    I am a new Mac user... and I love it so far. I have the new MacBook Pro and purchased the Airport Express and a Belkin USB hub along with it. I have the USB hub connected to a USB port in my computer (and a few externals connected to that: mouse, external LaCie hard drive, etc.). My question is, when I want to go wireless and move the computer to a different location... how do I safely/properly disconnect the USB Hub? If I just pull it out (gently, of course) I get a window popup that says something along the lines of "device was not properly/safely disconnected... etc." I don't want to cause any short or long-term damage. I just want to know the proper way to disconnect USB devices (hubs, mouse, external hard drive, etc.) before using the wireless feature of the notebook.
    Thanks!

    Bob,
    You're awesome, thanks! I tried that (pulled the external HD icon to the trash) then pulled out the USB from the Macbook and didn't get that "warning" box! I am currently only using two peripherals in my hub (a printer and the LaCie hard drive)... will I only need to do this "eject" thing for the external HDs? Or are there any other peripherals (I might use in future) that I will need to do this for as well?
    Thank you again!!

  • USB Device is gone Errors

    Hello,
    do you know how can we suppress USB disk error in /var/adm/messages?:
    1) First we had these kind of errors in messages:
    Nov 10 02:00:55 server1 scsi: [ID 107833 kern.warning] WARNING: /pci@0/pci@0/pci@1/pci@0/pci@1/pci@0/usb@0,2/storage@2/disk@0,0 (sd2):
    Our monitoring solution keeps an eye on any warnings on errors in messages file and reports false alarms in this case.
    2) Then we tried to suppress this warning by disconnecting USB device:
    server1-root:/export/home/root# cfgadm -c disconnect usb2/2
    Disconnect the device: /devices/pci@0/pci@0/pci@1/pci@0/pci@1/pci@0/usb@0,2:2

    What is trying to access USB? Is it USB controller or disk drive which is causing problems? How to completely disable this warning?
    Thank you

    I don't think it is HW/DVD issue. We have 60+ servers with this problem - the same usb warnings in messages file.

  • I have pluged a portable battery to the USB and my macbook pro stopped working after that, right before it shut down there was a message on the screen that said something like " USB device is withdrawing so much power, please disconnect and connect again?

    I have plugged a portable battery to the USB and my macbook pro stopped working after that, right before it shut down there was a message on the screen that said something like " USB device is withdrawing so much power, please disconnect and connect again?
    if the device I connected have caused this, shouldn't the macbook itself have some type of protection that should prevent this from happening.
    because when I took it to an apple certified maintenance shop, the guy said that now it could only run while connected to the power. it won't run on batteries. and that I have to change the motherboard.
    can I just replace the damaged part only, would apple consider this as a design issue and they could pay for it, or should I just buy a new motherboard for 800$.
    Help.

    BB1B2,
    The problem is in finding a tech shop that will/can do board level repairs on Macs. They are few. And I certainly wouldn't spend $800 on a new logic board - I would replace the computer if I had to pay that much!
    You could call around to a few repair shops and see if they feel competent to isolate the problem and do a board level repair - but I'm afraid, in the end, that your search will be futile.
    Sorry,
    Clinton

  • USB device keeps disconnecting/connecting after upgrading to Windows 8.1

    I have a device(Pedal for Sim Racing) connected via USB, everything is working fine in Windows 7 and 8 but after upgrading my machine to Windows 8.1 the device keeps disconnecting and connecting for like every 2 seconds. But after I open the Property Sheet
    in Game Controllers panel the disconnection issue was gone, if I reconnect the device the issue persist. Other people who have similar device also encounters the same issue after upgrading to windows 8.1. The issue persist with or without the device driver
    installed. 
    Any idea, what might cause this? 
    Best regards
    mark

    I'v got this exact same problem with my Win 7 desktop.  I've also got pedals and wheel but don't see it as different than all the other USB devices.  I'm using a bunch of USB, but no hubs, including 3 external storage hard drives. But the momentary
    disconnect appears in all devices as best as i can see..even my long time trouble free head phones..keyboard..and all.  Sometimes the sound goes away and if I unplug and replug them the sound comes back, and other times I have to exit and re enter the
    game. I also get video crashes ..maybe not related.IDK..and have to restart all, because I've got three black screens in Eyefinity. For years my system was trouble free and its just slowly started getting worse. I've thought it had to do with system "sleep"
    etc but long ago went to never sleep max performance etc..Makes no difference. Keep thinking its my hardware or my house wiring etc..But can't seem to solve it. I replaced my Mobo/chip/ram maybe 6 months ago and that appears to have not helped.  It seems
    to be getting worse. I hate to start replacing parts piece by piece..cost a lot of money and sometimes doesn't help.
    When I'm playing a game I can often hear "faint" sound of USB connect disconnect happening with regularity..that little bing/boink sound etc..So it must just be constantly happening...Seems weird. Didn't have anything like this happening years
    ago with pretty much the same hardware and same Win7 with the continuing updates etc.
    What can be causing this common problem?

  • Closed-lid mode USB devices disconnect randomly

    I just recently connected my MacBook Pro to my Samsung DLP HDTV and started running it in closed-lid mode so my TV is the primary/only display. I also have an external hard drive (USB), external mouse (wireless with USB toggle) and the new Apple bluetooth keyboard.
    The problem I have isn't entering the closed-lid mode. But once in closed-lid mode (after a short period of time) all of my USB devices disconnect and then reconnect. I know this because I get an error saying that my hard drive was removed improperly (please eject before disconnecting, etc) and I also get a message from my mouse software saying that my mouse has been disconnected. But then they reconnect themselves (hard drive shows up again on desktop and mouse software informs me that the mouse is present again).
    Has anyone had this problem before where USB devices disconnect in the closed-lid mode? I just upgraded to Leopard (formatted the drive and started from scratch). I never tried this within Tiger so I don't have that for a reference. This is really annoying because I have my entire music collection on the external hard drive and it just stops playing when this happens and I have to restore the path to my music collection within iTunes' preferences (it defaults back to ~/Music/iTunes/ when it figures out that the hard drive is no longer there).
    The strange thing about this is that when I don't run in closed-lid mode this never happens. I'll be more than happy to provide more details if needed. I greatly appreciate your help.
    Thanks!
    Mike

    i appear to have the same problem under Vista (via Bootcamp) on MBP (2007). i close the lid, and 5-20min later i hear the sound a USB device makes when it disconnects, and a minute or 5 later it reconnects. i don't actually have any USB devices plugged in, but there are several components in the MBP that are connected internally via USB (DVD drive, etc).
    what's almost as annoying is that the LCD backlight will come back on of its own accord, even though the MBP's been idle for more than the LCD/backlight time-out period. after the next idle timeout it turns off, only to turn back on againa while later. i see this under OSX & Vista.

  • ITunes crashes each time I connect/disconnect ANY USB device... OR even Ethernet

    Hi,
    I use the last version of both iTunes (11.1.5 64 bits, last version detected) and Windows 8.1 on an Asus G750J (64 bits) and for several weeks now iTunes crashes EACH TIME I connect or disconnect ANY USB device (not only my iPhone, but my external hard disk or my... mouse) and even my Ethernet port...
    None of my other softawares are impacted
    Thanks for your help

    Reinstalling the 64 bit version in the x36 programm folder seems to solve the problem but it's not satisfactory. I'd prefer to keep the advantage of beeing under the 64 bits version.

  • Ipod disconnects when too many usb devices are connected?

    i have a gigabyte 7VTXE motherboard, the right via drivers and XP sp3
    usb devices where it works:
    keyboard, mouse, ipod
    if i connect a hauppauge USB tv box or my speedtouch ADSL modem, it disconnects sometime soon after
    has anyone else heard of this? annoying isn't the word....

    You may be exceeding the total power available on the USB bus. If that is the case, one solution may be to get a self-powered USB hub. Connect the iPod and other devices that are frequently connected and disconnected on-the-fly to the hub. This will also reduce wear-and-tear on the more valuable USB ports on the computer. You can always get another $20 USB hub. Make sure it is the type that has its own power supply.

  • Mac Mini is disconnecting all usb drives whenever any new USB device is plugged in.

    I have 10.6.7 on a Mac Mini 2 Ghz Intel Core 2 Duo with 2 GB of ram and a 60 gig hard drive.
    It seems that every time I plug or unplug any USB device, it disconnects all the connected USB drives.  This seems to be something new, but I have not really often used the other USB ports either.  It is very frustrating, as you can imagine.  If I plug one drive in, and then plug another drive in, plugging the second drive it often disconnects the first one.
    But it is not just drives.  I can have only one drive plugged in, and unplug and replug the keyboard, and the USB drive will disconnect.  Then I will get message about how I did not safely disconnect the drive.
    Any help would be great.

    Yes.  One is a mini Toshiba USB drive with no other options for power.  But even unplugging an iPhone USB cord with NO iPhone attached to it will cause the drive to drop off.  The second USB drive I plugged in today had the same issues.  Basically I have to unmount a drive, then plug in a second device, then remount the drive using disk utility.  Very painful.

  • Please help me, USB Devices instantly disconnect/reconnect when using keyboard

    I own a Lenovo 3000 C200. IIf I start typing while I have any USB device plugged in (USB mouse, Removable HDD, etc), the USB device instantly disconnects and reconnects again. As long as I don't touch my keyboard, the USB device will work fine. I have noticed that this does not happen when I press the the other keys like the Lenovo care button, volume increase / decrease key, etc. and doesn't happen when I use the touchpad. I have not dropped or damaged my machine in any way.
    At the beginning, thinking it might be a windows problem, I had re-installed windows (XP) with no drivers installed and the problem persisted. I installed the latest update available for the BIOS still with no luck. I have checked the BIOS, however there is nothing related in anyway that can be configured.
    Just now I have noticed that the problem begins, as soon as I turn on the machine. Hardware problem perhapsI
    Please help me.

    This happened to me exactly the same, you must updated the latest bios version 2.06.
    Now go to the Lenovo website to download the oldest version 1.02  and the 1.08, first flash the 1.02 then flash again using the 1.08 that it, don't use the 2.06 which is the porblem source file for some 3000 notebooks.

  • Unsupported USB Device. Disconnect Cable.

    Hello EXperts,
    I am using Nokia Asha 200. I was trying to connect my phone using USB cable with my PC. I want to update the content of my phone. But I tried to connect, my phone shows an error message:
    "Unsupported USB device. Disconnect Cable". & windows didn't detect any device.
    I have Nokia suite 3.6.36 installed & I am using Windows 7 Professional (genuine). I have to restart the PC  but nothing happened.
    Anyone can please suggest my some solution.
    Thanks,
    Anuj Rathi

    i will reply to myself, for unknown reasons, it works when i plug it into the same usb port as previously, but it does not work (error message) when  i plug it into another port than the one where it was connected at first...
