Wierd problems, says the USB device not recognized

I have a 5 generation iPod, bought it Christmas, worked fine until two weeks ago, then whenever I connect it to my computer it sort of "works" for 5 seconds, then windows says "USB device malfunctioned, object not recognized" then the iPod freezes...
Can anyone help me?

I am having a similar problem. I have a new iPod 30GB video and the computer won't recognise it at all. I have restored, reset, downloaded Updater 2006-01-10. Very angry first timer.

  • USB device not recognized in Windows 7?

    I have the strangest problem I've yet to encounter with my computer.
    As you may have guessed from the title, I am constantly getting the message displayed.  Any fix that has been suggested has been unhelpful or worked for a bit until my computer restarted again (I'll get to that)
    First off it started when I noticed my mouse pointer was acting very weird, it was just a vertical line of dots.  A forum said an easy fix to the problem was to update my GPU drivers, which I needed to do anyway.  So after an update to the GPU drivers
    I log into my computer (which is password protected, this is slightly important to remember) and I try to go to youtube.  I click down at the start menu to type in chrome and nothing appeared.  I was able to move the mouse around and click on things
    but I was unable to type anything.
    Luckily for me I have a laptop as well so I checked for any solutions on my laptop and they said that it was a problem with the model of my keyboard specifically  This was odd to me considering most of the problems happened OTB for the keyboard and not
    a month after use, plus I was able to plug it into my laptop and it worked just fine.  When I plugged it back into my desktop it gave me the same problem: I couldn't type anything, I also noticed the little pop-up informing me that the USB device was
    not recognized.  "Well, great, time to get my backup keyboard," I thought to myself.  Except, that was not the case either.  I plugged my backup keyboard into every single USB port on my Computer Tower, even going so far as to unplug
    the mouse.  Absolutely nothing was working.  I constantly restarted my computer and each time got the same problem; I'm able to type in my password to log in and then a few minutes after that the USB device stops working.  Sometimes after plugging
    one of the keyboards back into a USB port I would get a message saying it was installing drivers; and then would fail in installing any.
    After a bit I navigate through the menus with just my mouse and do a system restore to before the GPU drivers were installed.  After that, I started windows in SafeMode and then turned my computer off.  Finally, I unplugged my computer completely
    of all plugs (including my power plug), waited a few minutes, then plugged everything back in again.  Amazingly, this fixed the problem, but then it got worse.
    After about an hour of gaming, my computer BSOD's, most likely because I decided to alt+tab out of Tomb Raider during a loading screen to stop a video I had on.  I restart my computer again, and then the problem returns, only this time absolutely
    no USB devices work except my one keyboard.  The backup keyboard, and both my regular mouse and backup mouse stop working a few minutes after logging in.  I try to fix the problem like before, but to no avail.  Any USB device I plug in either
    gives me the "USB device not recognized" or attempts to install the drivers and then fails.
    If there is ANY way to fix this problem, it would be greatly appreciated.

    Try cleaning the connector on the bottom of the phone. Use a magnifying glass to see what is stuck inside, a dry toothbrush and/or wood or plastic toothpicks (nothing metal). If that doesn't resolve the problem your phone is broken.

  • Windows won't recognize my iPod - USB device not recognized

    This is really frustrating. So I got a 4gb iPod nano on Saturday, took it home, set it up and everything was going just fine, no worry's. About 4 hours later I went to adjust my songs and it would not come up in iTunes. A little pop-up box said that the "USB device not recognized - one of the USB devices attached to this computer has malfunctioned and windows does not recognize it." After owning my iPod for less than an afternoon, I now have an ipod that I can do nothing to including change the music, charge it, etc. It works normally otherwise, it just won't connect to my computer. I then plugged in my older 256mb usb stick, and the same message, it too does not get recognized by windows. So I then tried a brand new 1gb usb stick that I had and the same result, not recognized by windows. I updated my itunes to the latest one after purchasing my ipod (version 7.4.3.1) and have looked up everything that I can and tried everything I saw to try, but nothing, absolutely nothing, worked. However my usb mouse, usb joystick, and usb printer all still work, but my moniter that has four usb outlets on it causes the same message, if I plug in the cable that connects one usb on my computer to the four on my moniter, windows can not recognize it. When I look in my device manager at the "unknown device" under the usb controller list it says that there is not driver for it, however I know that the drivers are either on my computer or built into windows. Any help? Anybody have an idea about what to do? Is it something in my windows registry has changed because of the new itunes, etc.?

    Now that I've had some sleep, I realise I didn't really provide information that may lead to some specific help. Here goes - when I first plugged in the ipod nano (8gb), It displayed the screen it was supposed to - I could see the lightning bolt through the battery icon and knew it was charging. The icon for the ipod also appeared in the left-hand listing in itunes (in the section that existed under Library, before the sections Store and Playlists). This section now does not appear (I can't remember the title of this section, but it might have been 'devices'). In fact, I'm pretty sure this problem started when I clicked on this icon - nothing happened and it disappeared - so did the display on the ipod, which is not just the apple. This means itunes has only Library, Store and Playlist in the left-hand colunm. While I accept that computers do not work on normal logic, this seems to me to indicate that the drivers are fine, the system is fine, my laptop is fine - its the ipod or the usb cord. This morning as I tried again, this time my laptop gave me the option to 'click on the balloon to solve the problem' - let me quote: "One of the USB devices attached to this computer has malfunctioned, and Windows does not recognise it. Try reconnecting the device. If Windows still does not recognise it, replace the device". Come on folks - one of you will surely know how to fix this (short of me taking the ipod back to the store to get my money back).

  • USB Device Not Recognized - USB device attached has malfunctioned & Windows does not recognize it

    I have an HP Pavilion dv4 Notebook running Windows 7 Home Premium and the USB ports worked fine for an HP deskjet printer and an older Casio digital camera. Then one day, the laptop decided not to recognize the Casio digital camera and gave the error message "USB Device Not Recognized" and also indicated that the device attached to the computer has malfunctioned. This prompted me to buy a new Canon digital camera. Well, a new camera did not fix the problem. Now, anything connected to either of the 2 USB ports will not be recognized by my laptop. Help!  I'm at a loss to figure this out.  I've tried the suggested Microsoft help below: 
    Suggestion 1: For the issue with USB devices, uninstall and re-install all the USB controllers. This lets the controllers recover the USB port from its unresponsive condition.
    The USB controllers represent the USB ports in Device Manager.
    a. Click Start, type device manager in the Start search box and hit Enter.
    b. Expand Universal Serial Bus controllers.
    Note: You might have to scroll down the list to find this item.
    c. Right-click the first USB controller under Universal Serial Bus controllers, and then click Uninstall to remove it.
    d. Repeat the above step for each USB controller that is listed under Universal Serial Bus controllers.
    e. Restart the computer. After the computer starts, Windows will automatically scan for hardware changes and reinstall all the USB controllers that you uninstalled.
    f. Check the USB device to see whether it is working.
    This did not correct the problem.  Then from device manager, I tried updating drivers on all the USB controllers and root hubs. While some may have received downloaded software updates, it still did not correct the USB device not recognized problem after restarting the computer.  I'm hoping someone knows of the fix to this situation and can pass it along to me. Thanks for reading and posting any help.

    Hey 655micha, 
    I'm sorry you're having an issue with a USB device. Do you get an error window that pops up? If so what does it say? Have you checked Device Manager? Is is just one device that isn't working? Has it ever worked before? Is it just one USB port in particular that isn't recognizing devices? 
    What model do you have? Here are the steps to find your product number. FN + ESC is the easiest way to find that information. 

  • USB Device Not Recognized Message

    Hi,
    I constantly get this message and it also says
    one of the USD devices attached to this computer has malfunctioned and Windows does not recognize it, For assistance in solving this problem, click this message.
    When I click on it,A box appears and is BLANK( It says the location of the device is shown in bold type).
    I went to system devices and uninstalled 5 USB devices and nothing changed except my computer reloaded them?
    I have a Satellite windows Vista.
    Also I can not start my computer at times and when I push F12. It try's to repair the problem and can't it gives me pretty much the same message.
    Can anyone help?? This darn message go off and on constantly..
    Any info/help appreciated, Valerie

    This did not work for me. I have a laptop that was running Windows XP, and it had no problems recognizing the iPod. I was having problems with XP, and rather then reinstall XP, I did a clean install of Vista. I did a settings transfer, so the new install of iTunes came already configured--I mention this since I don't know if it was a factor.
    When I plugged in the iPod, I got the USB Device Not Recognized. The usbstor.inf file did not fix the problem. However, the solution at http://www.winvistabeta.com/groups/275128/ipod-usb-device-not-recognized/message .aspx did fix the problem. Do this:
    Reset the iPod:
    1. Unplug the iPod.
    2. Turn the hold switch to HOLD and then back to off.
    3. Hold the Center and Menu buttons for 6 seconds until you get the Apple logo when you release them.
    4. Plug in the iPod. It should now be recognized.
    This worked fine for me the first time. Thanks! Jack

  • USB Device Not Recognized issues

    I have a Qosmio X505-Q860 and I've been getting the 'USB Device Not Recognized' error constantly for several months. I've never plugged anything into any of my USBs and the error is now causing a nice Blue Screen (which happened about 4 times yesterday within 1 hour). I've tried uninstalling the problem USB hub but it keeps telling me that it failed to uninstall (I'm on my administrator account when doing this). How in the world do I get rid of this so my computer stops crashing and driving me crazy!?
    Edit: I should also mention that everything is up to date (I check often and checked just now).
    "A stopped clock is still right twice a day."

    I suggest trying another USB cable. If you are positive that your cable is not the issue then try resetting the iPod and booting into disk mode (Hold menu+select down until Apple logo appears. Then hold menu+play/pause down and the iPod will go into disk mode, see if the computer recognizes it then. If that works then their is either a software issue on the computer or a firmware issue. Worth trying to restore but backup all your iPod's files first!

  • 2G Nano-USB Device Not Recognized message

    2G Nano has been sitting for months. Decided to use it as a backup. When connected to computer (tried on 4 different computers running iTunes) I get a "USB Device Not Recognized" message. It shows up in "Device Manager" as an "Unknown USB Device" not an "iPod". Have performed the required 5 Rs and it still will not work. Any help would be greatly appreciated!

  • Zen Extra "USB Device Not Recognized" ??? HEL

    Hi all,
    I had a MPIO 20 gb MP3 player wich was stolen. No biggy, I took advantage of it and upgraded to a Nomad Jukebox Zen Extra 30gb. It look and feel nice and the navigation seems really easy. Where it gets more difficult is the "simple" pluging in!!! No matter wich USB port I use on my PC, I always get the "USB Device Not Recognized" message. Front port, motherboard port nor soundcard port (Audigy2) dont work.
    Any advice, I really need help here!
    Thx for your time,
    Jacq
    Montreal, Canada.

    I just bought a Zen Micro and had the same problem, the issue is with the USB cable. I had an extra cable from my digital camera and using it, the Zen Micro was recognized immediately. I've seen the issue posted here by other people too. You could try to return the player and chance getting another one with the same problem. If I didn't have a spare one, I would have just picked up a new one up at Radio Shack or Best Buy...

  • I have a new Nano and I get a message that says the USB device is not recognized by my computer and I cannot set it up.

    I have a new IPod Nano and when trying to connect to my PC for the first time I get a fault message that says the "USB Device is not recognized by my computer. I have several other IPod devices and have never had this problem. When I go to windows explorer, the device does not show at all, so I cannot manually open it.

    Hello JETaylor2015,
    Congratulations on your new iPod nano!  I would be concerned too if my iPod was not recognized by iTunes or my computer.  I recommend reviewing this article for steps to take when your iPod is not recognized:

  • I have an Iphone 5S and used to sync it to my computer in the past without any problem, but now I can't and appears the message "usb device not recognized", and the cable is good and so the USB port. Do you have any idea what's the problem?

  • TS1369 Hello! I have an Ipod Shuffle 2nd Generation and it is not recognized by my Windows 8 based laptop. An error message of 'USB device not recognized' is shown. I have the latest ITunes version installed, and tested the dock in other pc's.

    Hello!
    I have a problem connecting my Ipod Shuffle 2nd generation to my Windows 8 based laptop. The computer doesn't recognize the Ipod and issues an error message saying 'USB device not recognized'. I tried uninstaling ITunes(latest version) and all other Apple software and reinstaling it back again, checked my USB hubs in the 'Device Manager' section of the Control Panel, you name it.
    I could really use some help solving this.
    I've turned to the troubleshooting section in Apple Support but it has nothing concerning situations in wich the device isn't even shown in the 'My Computer' folder.
    Help a brother out, will you???

    Found a solution in another forum http://en.kioskea.net/forum/affich-63733-ipod-not-detected-on-computer (a few posts down).
    It was for an IPOD so you can see those details in the link.
    Found how to reset a shuffle and inserted it into these instructions - did not have to follow his last steps.
    - Turn off computer.
    - Plug Shuffle into usb.
    - Then you must reset your shuffle
    To reset iPod shuffle:
    Disconnect iPod shuffle from the computer (if connected).
    Move the switch on the iPod shuffle to the OFF position. Note that when iPod shuffle is off, the green stripe by the switch is not visible
    Disconnect iPod shuffle from the computer (if connected).
    Move the switch on the iPod shuffle to the OFF position. Note that when iPod shuffle is off, the green stripe by the switch is not visible.
    - Start computer and it should install the usb driver for the ipod automatically.
    - Your i pod will say do not unplug so don't. then open itunes and it will be there.
    I did not have to do these thing below – did not get error message and shuffle was displayed in Itunes. / LMc
    Just remember to not only eject ipod from itunes but stop usb.
    Go to the program icons near the clock and right click the usb icon and "safely remove hardware" will appear and click it.
    Stop it and select "apple ipod".

    When I plug in my sons ipod nano 7th generation, just recently says usb/device not recognized and doesn't light up when plugged into the wall either??? Any suggestions??

    This came from another thread, but worked for me.  Problem is with newest iTunes 4.62.  Unistall iTunes, as well as its helper programs (Apple Application Support, Apple Mobile Divice Support, and Apple Software Update).  Reboot, and reinstall iTunes.  It will reinstall all the other ones and you should be able to connect your nano.  Good luck.
