  Hi all

  I've already installed Windows 8.1 Pro x 64 and on Device Manager, I always 2 missing drivers, they are PCI Device and unknown device?

  Please see attached a printscreeen. Any idea of what are the missing drivers?

  Thanks to you all

  Hello:

  You need this driver for the PCI device...

  http://h20566.www2.HP.com/hpsc/SWD/public/detail?sp4ts.Oid=7089928&swItemId=ob_134503_1&swEnvOid=4158

  I gave you the driver for the unknown device when you W7 on the machine, so it's probably the same as.

  http://h20566.www2.HP.com/hpsc/SWD/public/detail?sp4ts.Oid=7089928&swItemId=ob_132986_1&swEnvOid=4158

  If it's not this one (or you had two unknown devices at the same time and already install the driver 3D driveguard), then it's probably that one...

• One of the USB devices attached to this computer has malfunctioned and Windows does not recognize it. The location is the root (2 ports) USB hub: 1-unknown device and Port 2-not used

  Original title: USB device not recognized

  Over the last 2 weeks, I get a message on a USB device.  The message said that one of the USB devices attached to this computer has malfunctioned and Windows does not recognize it.  The location is the root (2 ports) USB hub: 1-unknown device and 2-unused Port.  I have no idea what it means.  I hesitated to first click the icon (it does not last very long) thinking it could be a scam.  Can someone help me?  Thank you.

  Hello

  (1) is the specific question of specific USB devices?
  (2) did you of recent changes to the computer before the show?
  (3) have you tried plugging the USB stick on another computer?

  (4) what is the brand and model of the computer?

  I suggest to refer to the following methods and check if it helps to solve the problem.

  Method 1: Hardware devices do not work or are not detected in Windows

  Run Microsoft Fixit mentioned in the article.

  Method 2: USB Port may stop working after you remove or insert a USB device

• Why am I suddenly "USB not recognized, one of the devices USB has malfunctioned and Windows does not recognize"

  Hi all. If anyone out there in Cyber Land can solve this problem for me so I've personally you will issue an eight-pack of ice-cold beer (or a bottle of wine for the ladies lol)...

  I'll try not to waffle too guys, so here's...

  Right my PC running Windows XP. I also have itunes installed on my PC (I have an iphone 4). Upward until yesterday my iphone and itunes were working well, (once I plugged my iphone in the itunes USB port recognised that my iphone was plugged and synchronization was fine etc.).

  But now when I plug my iphone to PC to sync with itunes, I get a pop up box on the lower right part of the screen that reads... "USB not recognized one of the USB devices has malfunctioned, and Windows does not recognize."

  After visiting about 5 different sites now "Ways to solve this problem", believe it or not, I still have the problem bloody! :(

  A site proposed shutdown PC and unplug it from the power supply, then plug it back start-up and back... this as did not work!
  The other they say that I should go to Device Manager, uninstall all the USBs then restart... it did not work either.
  Tried a system restore
  Tried to reinstall itunes

  When I check the names USB in Device Manager, there is one who reads unknown device. I am literally pulling what's left of my hair now. I tried to solve this problem for almost 2 days now and still no joy. That's why no matter what input you guys would be very appreciated. I'm no PC Wizard, so please, don't think you're patronizing me if you break down things step by step for me.

  Thank you comrades, cordially, Freddy frustrated. :)

  Another said I should go to Device Manager, uninstall all the USBs and restart.

  Usually, this works... but can be very dangerous, unless you have a PS/2 keyboard.

  I also assume that you have tried all other USB ports on the computer. tried a verified USB device (for example, a flash drive) in the USB usually when you plug in your iPhone. and I tried your iPhone in another computer (I know it's rare for an error message Windows really means what he says, but sometimes the material lacks).

  Is the charge of the iPhone when it is connected to the USB port (I don't think)?  This happened to me recently, but a reboot fixed it.  I guess that that happened to you.

  I guess that you don't see the error messages in Device Manager or you must declare them.

  You can uninstall all USB devices that do not exist as follows:

  • Open a command prompt window (start > run > cmd > OK)
  • Enter the following command and press enter

  Set devmgr_show_nonpresent_devices = 1

  • Start the Device Manager by typing the following in the same command prompt window

  devmgmt.msc

  • In Device Manager, click the view menu and select "Show hidden devices".
  • You should see a category just after "Non-Plug and Play drivers" named "other devices."  Chances are that there will be a big exclamation yellow mark beside it.  When you expand the "other devices" you should see several non identified "USB devices."  Uninstall all this.
  • Reboot (with the iPhone NOT connected).

• Error "one of the USB devices attached to this computer has malfunctioned and Windows does not recognize it." when you connect Logitech M225

  Original title:

  My wireless mouse works fine for the last 2 months, now, all of a sudden it doesn't work at all.

  I get a windows notification that says-

  "One of the USB devices attached to this computer has malfunctioned and Windows does not recognize it."

  I have Vista 32 bit OS on my laptop.

  My office has Windows 7 32 bit and I am able to use the mouse on this computer, then the M225 is not defective.

  I tried to look for a download of update on the site of Logitech & only found:

  6.32.20 set - point it did nothing to help.

  I also tried to move the receiver to the other 2 ports USB w / still the same results.

  Are there other downloads or solutions that will help w / this problem?

  You can also try searching for devices strangers (with yellow symbols) in the Manager under the mouse devices and other pointing devices and other devices (if any). Right click and uninstall unknown devices. Then restart.

  Also try the steps below to reset the power of USB:
  (a) the laptop off, unplugged from the wall outlet.
  (b) remove the battery for a few minutes, then reinstall it.
  (c) then restart the laptop.

• Device USB not recognized - device connected USB has malfunctioned and Windows does not recognize it

  I have a HP Pavilion dv4 laptop running Windows 7 Home Edition Premium and the USB ports worked well for a 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 connected to the computer has malfunctioned. This prompted me to buy a new digital camera Canon. Well, a new camera has not fixed the problem. Now, anything that is connected to one of the 2 ports USB will not be recognized by my laptop. Help!  I am at a loss to understand this.  I tried using Microsoft suggested below:

  Suggestion 1: the problem with USB devices, uninstall and reinstall all USB controllers. This allows controllers to recover the port USB of his condition does not respond.
  USB controllers represent the USB ports in Device Manager.

  a. Click Start, type Manager of devices in the search box of start and press ENTER.
  b. expand Bus USB controllers.
  Note: you may scroll through the list to find this point.
  c. the first USB controller under Bus USB controllers right click and then click on uninstall to remove it.
  d. Repeat steps above for each controller USB is listed under Bus USB controllers.
  e. restart the computer. After the computer starts, Windows will automatically check for changes on the hardware and reinstall all USB controllers that you uninstalled.
  f. check the USB device to see if it works.

  This has not fixed the problem.  Then the Device Manager, I tried to update the drivers on all the USB controllers and root hubs. While some may have received software updates downloaded, it still has not corrected the problem of unrecognized USB device after the computer is restarted.  I hope that someone knows the solution to this situation and can pass it on to me. Thanks for reading and any help display.

  Read previous messages revealed the solution for USB devices not recognized on my HP Pavilion as well as several other laptop models.  Shut down the computer and remove the battery and wait for about 15 minutes. Reinstall the battery and restart the computer.  USB ports are working to download pictures from my digital camera from Canon and charging a cell phone, etc...   I hope it helps others with this problem!

• found new hardware wizard appears and unknown device device Watch Manager

  Since a few days ago, the Add New Hardware Wizard keeps popping up. I looked in Device Manager and found an unknown device (yellow exclamation mark) should I delete the device? I don't know what to do to identify which device is unknown.

  If you remove it, then he'll probably be back the next time that you start.

  go to start / all programs/windows update (at the top of the list of the menu), custom search, watch your optional hardware updates and search for a driver that you have not already installed, you can get lucky. Otherwise post the details of your specifications and ask again.

  Furthermore, it can take a while to get the pages updated and you may need to install active x on the way, a line will appear at the bottom of the fixed part of your browser screen (the same as when you download) If this is the case, click on it and install active x, then a box should appear and tell you allow I think.
