  Tried to reinstall windows did not help...

  is there a solution?

  Hello

  Hmm. First of all, you should unplug all external USB devices.
  Then go to Device Manager and remove it all concentrators root USB and USB host controllers.
  Reboot the laptop.

  After this procedure, the operating system should recognize and should install new ports.
  Now you can connect to a plug - and play instruments. These devices should be recognized automatically. But some external USB devices need additional drivers.
  Usually these drivers are provided with the USB device.

  I would recommend this review if necessary!

  I really need help! I don't know what else to do... I need to work on this computer. It's a Toshiba Satellite Windows Xp SP3

  I just went through two weeks of tampering with my 'old' computer trying to recognize my new 4370dn Canon multifunction printer after installing Windows 7.  I tried to reinstall Windows XP, uninstall the USB ports and hubs in Device Manager, update the printer drivers and several combinations of these elements.  In my case the ports would recognize external hard drives and flash drives, but my printer would come as a device not recognized.  Finally, what worked for me was to uninstall all the ports/USB hubs listed in Device Manager (they get automatically reinstalled with a soft reboot of the computer) again, download a driver from the Intel website (http://downloadcenter.intel.com/confirm.aspx?httpDown=http://downloadmirror.intel.com/16023/a08/infinst_autol.exe&agr=&ProductID=&DwnldId=16023&strOSs=&OSFullName=&lang=eng) chipset installation utility and restart the computer.  When I plugged the USB cable from the printer, the normal process of new device was launched.

• Peripheral PnP USB - muted, is unplug sound when not touched, "device not recognized" or a malfunction, etc...

  Here is an exhaustive list I hope what happens (it's the Microsoft forums, so I think you guys are going to read a lot of information):

  • The sound on my PnP USB audio device cancels randomly without any reason. It is not to be touched at all, and often happens when I'm even not listen to all the sounds.
  • Before he died, it emits a blur in the helmet noise as it is to be disconnected or the cord is cut or something. I have to unplug it and plug it back several times to make it work.
  • It has been for several months, working properly, this month started anything, for about a week.
  • I can't use my headset because it is loose. I had the USB key to solve this problem, because it's too expensive get taking fixed. I did not buy the device at first hand, I got it from a family member who took my laptop in for repair and the guy he recommended and we sold two of these jacks.
  • When it goes off during a game, I can't sound to return. Sometimes I can fix it on a game (as Portal 2, for example) by going to options and change the type of sound (or any) what's called it headphones to speakers, then back to the helmet. However, the game freezes often when the sound goes off and I have to remove the usb key, and in this case the game should also be repeated. In addition, everything has sound options like that.
  • This happens randomly, but it tends to happen every five minutes or every few seconds, and coincidentally it almost always happens during a loading on a video game screen.
  • It is not always give me a warning sound, especially on the games. He's just quiet.
  • Device Manager does not display a point of exclamation or question marks next to any audio device and the key USB pnp is indicated correctly. In the options of the sound in the Control Panel, there is of the sound bars next to the USB key that indicates that his is read, but it is not in playback mode. The USB pnp is listed as default device, so don't tell me to do. The microphones are turned off as well.
  • It does the same thing in all my usb ports.
  • The driver is up-to-date and meant for Windows 7.
  • I do not install the Windows updates. Updates are bad.
  • Box for what he calls a "USB stereo Audio Adapter external" StarTech.com, or "ICUSBAUDIO". It came with a disc that I used to install the driver, and I went on their website to get one for Windows 7 specifically and installed.
  • I use a computer laptop 64 bit Windows 7. In Device Manager, there are three things listed under sound: Realtek High Definition Audio Intel (r) display Audio and USB PnP Sound Device. None of the USB devices have exclamation points.
  • For the first time today, when the usb unplug sound, my computer tells me "Device not recognized" and said it could have malfunctioned. When I clicked on it for more information, he said that he could not tell me what the usb was even because it was not plugged in, which was not true. I also had a window appears which has tried to install the device driver (already installed) and then was told that the unit had been disconnected before he could do (not true). It just happened, for the second time today a few seconds ago.

• Device not recognized USB keeps popping up - Windows 7

  I have been using a wireless keyboard with the Sony Vaio laptop with Win 7 64 bit for a year and, yesterday, the keyboard no longer works.  The keyboard works fine with 2 other laptop computers (Win7 and XP).  Even when I unplug the dongle, the message "USB device not recognized" keeps popping up ever minute or more.  All other USB devices (i.e., memory keys, portable HDs, etc) work very well.  I uninstalled all the USB controllers in Device Manager and rebooted (multiple times).  I tried to go back to a system since a couple of days restore point.  Nothing solves the problem.

  I connected the USB cord to transfer information from your old phone to new phone via Itunes.  Since that time that I keep getting a pop up message that says: device not recognized USB, the defective device, windows does not recognize.  Nothing is plugged in, but message appears every few seconds.  How can I get him to stop?

  Hello

  It seems that you are getting the popup "USB device not recognized", when nothing is connected.

  What is the brand and model of your computer?

  I suggest to uninstall the USB controllers and check if you get the context menu.

  
  

  Method 1: Remove and reinstall all USB controllers

  
  

  a. clickStart, type devmgmt.msc in the start search box and press ENTER.

  b. expandBus USB controllers.

  c. right-click on each device under theBus USB controllers node and then click Uninstall to remove them one at a time.

  d. restart the computer, and windows will install the rear USB drivers.

  If reinstalling USB host controllers fails to resolve the issue, go to method 2.

  Method 2: See the procedure suggested by johnkelly46 responded on October 26, 2009, from this link.

• USB device not recognized... Unplug the thing does NOT work

  It baffles me that THOUSANDS of people have this problem, or a variant of it, and no ONE at Microsoft or elsewhere also offers a real solution. Unless of course you want to count the method "unplug your computer", which is the most foolish band-aid for a problem I never heard, even if it works for a lot of people (most). I, unfortunately, am one of those for which the "disconnect" method magic does NOT work. I tried everything what all other posters and responder suggested (BIOS upgrade, change Legacy BIOS definition Enable to disable to activate again, driver updates, uninstall all USB, full power down and restart hours later, use CMD prompt to show only devices, etc.) and do not know what else to try. I would really like to see a REAL answer as to the cause of the majority of the questions posted about the USB error outside the usual "restore your settings, use your restore disk, unplug it, replace your USB key, etc etc etc. HEY! MICROSOFT! SOLVE THE PROBLEM! OR, Hey, here's an idea, a news for you, I'm sure that... don't they exude products until they have been tested (NO! I mean really, fully tested [see XBox 360 RROD])

  In case anyone reading this is a real working solution, I'm on a Toshiba A135-S2386, Vista Home, and each USB port is unusable on any device. All ports feeds the device and noise sounds to indicate that a USB device was attached and then proceeds to the display of the error "USB device not recognized" and shows and shows an unknown device connected. It does this for any USB device.

  FINALLY: PLEASE PLEASE PLEASE DO NOT POST A REPLY IF YOU USED THE METHOD OF "DISCONNECT", AND IT WORKED. Grats to you for fixing your computer, but I can just not read another 400 posts of "wow it worked for me great fantastic" when it does NOT work for everyone. I need something new and real. (Sorry to be all grumpy, but I'm tired of these kinds of problems from companies making billions off the coast of junk, defective, half finished, produced a car!) "You listen to Bill?)

  UPDATE: just ran a scan of the system file Confirmation via an administrator command prompt and it's clean...
  ALSO - was not that before, but now whenever I do a complete power down / reboot thing that it gives me a "Bad Checksum" error and I have to reset the date and time in the BIOS. I need to change the battery in MB? As I said it did not have this before and the USB error was produced, but could this be the problem? Bad battery MB CMOS?

  The bios of your motherboard is probably damaged.

  step 1. See if you can find a previous version of the bios of your motherboard and return date of the bios.

  step 2. Find the latest version of the bios of your motherboard and update your bios.

  Do not use a registered version of your current version.

  To check the problem is the motherboard or operating system. find something like a live Ubuntu CD

  http://www.Ubuntu.com/desktop/get-Ubuntu/download.

  or

  Make a Ultimate Boot CD for Windows

  http://www.UBCD4Win.com/index.htm you are using windows xp or borrow a copy to UBD4WIN.

  Both of the above run in memory (does not load on hard drive.

  Both a bit slow, but are excellent tools.

  Works like a normal computer.

  If you can see you USB devices, magicjack, ETC. your BIOS is not corrupt or motherboard problem.

  In normal windows if you see not the USB devices, magicjack, etc your windows install is corrupt.

  Reload Windows of difficulty.

  If you you do not see the magicjack, USB devices, ETC., your BIOS is corrupt motherboard or other problem.

  Redo your BIOS as described above.

• Device not recognized USB - mouse

  Hi - write a new thread that I raised in a previous which I suppose is not sought at the most. Mods - delete please if you always looked at the other thread.

  I started intermittently gel experience with my old USB mouse, so I replaced it, that to have my new mouse (Canyon CNR-MSL7) begin to experience the same problems. Intermittent at first, but it became unusable over time - error "USB device not recognized". I tried two mice in another PC and they work fine. I use Vista is said by the way.

  I had a hard disk separated on my laptop (Sony VAIO VGN-AR71S) failure so I sent away for repair. I advised the hardware failure Sony and my USB mouse problems - she is back with a new HD but they said they found no defects with the USB.
  the mouse worked for about 1 day before I started getting the error 'USB device not recognized' again.

  A system restore will obviously work for me because my hard drive has been replaced and I have the same problem I had before, despite the installation of the more updated version of vista to Sony.

  The laptop has the most until drivers date etc, but does still not more than 95% of the time. I went through different threads here and I checked that everything is fine with the USB etc hubs, but not joy.

  I checked the ports are feeding correctly and that they are.

  I tried power down, stop and remove the advice of battery given here that seems to have worked so well for people but it does not work for me unfortunately.

  Is someone of MS can advise if it is sought in order to create a solution that works for those of us who does not work for the option "disconnect"? I tried all the solutions to this problem listed on the various threads on this subject in this area and other forums. Or can someone tell me if there is anything I can buy to remove the problem? Equipment etc? I thought that an upgrade to windows 7 could help, but I've seen a lot of discussion here that clearly show the same problem that appears for people who use it.

  Another new mouse like the ticket to me if you have hardware problems (and this is
  my best bet).

  "USB device not recognized - one of a mulfunctioned USB devices" - this sign always appears when I sync my Treo 750. After a few attempts WM Device Center finally can 'see' Treo and this sign disappears. What I supposed to do? Find a driver for Treo or what? Could someone help me please?

  In your 750, go to start > programs > USB to PC. There, you will see a check box. If it is not checked, check it, if it is checked, uncheck it. After that try to sync your device to your PC and let me know what happens.

• PRS-600 USB device not recognized

  I am unable to get ereader PRS-600 to be recognized by the computer (Win7).
  I tried to update the software (even if I think it's in)
  (date) but the window 'connect a PRS-600 to update' does not progress and the update button is dimmed.
  I deleted the "unknown device" in the drivers, but when I reconnect the USB cable and the ereader, I always get the display of device not recognized and the message "USB device not recognized".

  I seem to have solved the problem. I contacted Sony through esupport and a chat with a tech.

  Make sure that the battery has some charge inside. Completely charge if you can.
  Stop eReader (fully)
  Remove the SD card
  Press the button Reset (at the bottom of the ereader)
  Turn it on
  While the display shows "Open book", at the same time press the button to "turn the page" (back) and the Volume button until the "Reset All" + screen
  Enter 'Yes' to reset the ereader. You may need to configure the screen (X button with the tip to draw at various points)
  If you charge the battery, you may need to contact the support chat for sorting.

• His number disappointed + B500 USB device not recognized at startup

  Hello

  We have 2 B500

  whenever I'm starting, after loading windows they give me an error "USB device not recognized" I don't know what to do any help will be greatly appreciated as it is strange that both machines are giving the same error.

  also on one of the machines the sound does not work, I tried to get out of trouble, the diagnostic says the speakers are working properly, but not her out at all.

  I'm kind of disappointed by these questions, we always buy at Dell, but we thought we would give Lenovo a chance, the machines were barely a few months, when the problem started.

  advice please?

  That error usually comes up when a non bootable USB device is connected. Check the Bios and make sure that the CD drive and HARD drive are loading first. That should solve your problem. If this is not the case, make sure that you don't have any USB stick or disk external HARD connected until the PC load.
