Hello Ashraf.

Thanks for posting your query in Microsoft Community Forum.

  1. You did it any significant hardware or change software on the computer before this problem?
  2. Do you have an error message when it is not detected? If YES, what is the exact and complete error message that you receive?

I understand that the USB device is not detected by your computer. The question may arise if the currently loaded USB driver has become unstable or damaged or if your PC requires an update for problems that could conflict with a device USB and Windows. This can also occur if your USB controllers may have become unstable or corrupt. So, I would suggest trying the following steps and check if the problem persists.

Method 1:

Please try the fixit (s) provided below which will help you solve common problems associated with devices and USB ports.

If method 1 does not work, try Method 2.

Method 2:

Remove and reinstall all USB controllers.

  1. Open Manager devices by clicking the Start button, click Control Panel, click system and security, and then, under System, clicking Device Manager. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.
  2. In the list of the categories of equipment, locate and expand Bus USB controllers.
  3. Right-click every device under the Bus USB controllers node and then click Uninstall to remove them one at a time.
  4. Restart the computer and let the USB controllers get reinstalled.
  5. Plug in the removable USB device and test to make sure that the problem is solved.

If the problem persists, go to method 3.

Method 3:

This method will install the latest drivers from device to your USB device.

  1. Click the Start button, type Windows Update in the search box, and then click Windows Update in the results pane.
  2. Click find updates. When the scan finished, click optional review updates.
  3. Click the check box next to the update, and then click install updates.
  4. If you are prompted, read the license agreement, then click I agree.
  5. Follow the instructions on the screen to download and install updates.
  6. If you are prompted, restart your computer.

More information: Update a hardware driver that is not working properly

If the device fails after updating the driver, you can try to roll back the driver with its previous version.

Restore a driver with its previous version

Hope this information is useful. If the problem still persists, please post back for further assistance, we will be happy to help you.

  • The Windows XP Explorer crash when checking the USB SD OEM-builtin card reader properties

    Hello, people.

    It's my only known PC malfunction, and initially, it worked without problem. The question began at a time not very long before a recent update failure. The problem is related to the card reader SD OEM-builtin of the Pavilion. Windows XP is unable to connect to this player when my 4 GB SDHC card is slipped into the SD card reader, an error box quote as 'due to an error IO peripheral."  and somehow this blocks / crashes Windows explore (IE no.not) with the 4 GB card in drive F:-SD reader.  But Windows and the reader work very well when my 32 MB SDHC card reading. Both the 4 GB and 32 MB cards work fine in my Canon Power Shot and I can download the contents of the card of 4 GB (JPEG format) via a mini-USB cable for the camera as always, but burning the battery juice in the batteries in the camera. I'd rather take the camera SDHC card and empty its JPEG files in the SD drive. I don't think that it is able, barely used player until three or four months ago. I'll also post this question to the Canon forum and maybe HP forum, but I would like to have some ideas as well on the side of Windows.

    It occurs to me, I don't know how many contacts on the card is active in dealing with the 32 MB. I expect that the 4 GB card should use almost all of the pins; I was wondering if a unused pin in size of 32 MB can be failed do contact and this could corrupt the ease of use of the 4 GB card.

    FYI - my system is HP Pavilion a1020n, five years old. It includes the processor Intel P4 CPU, has 130 GB free on the system partition, and has been upgraded from two years to 2 GB RAM DDR2 PC2 - 4200. OS is Win XP Professional x 86 SP3 with .net all Frameworks 1.1, 2.0, 3.0, 3.5, 4 customer and extended 4, IE 8.00.6001.18702, most Silverlight 4.0.50917.0 to patched. All the .NET Frameworks are patched, except that the last .NET two patches for the version 2.0 and 3.5, KB2418241 and KB2416473, both failed several trying to install, and I'm looking for help with that in a posted question, but if you think of these malf are linked, please let me know.

  • Satellite U840-10N - Windows Installation can not see any drive

    Hi all, this is my first post so I hope that I chose the right place to post in.

    I just bought a new Toshiba Satellite u840-10n ultrabook. He joined WIndows 7 Home Premium 320 GB HHD + SSD of 32 GB.

    Even though I prefer Linux, I need Windows because of Microsoft Visual Studio. I downloaded Visual Studio (legally throught dreamspark.com), but it looks like it has some issues. In particular, I can't create any project.

    After searching the Web for this problem, I decided to try reinstalling Windows, hoping that this will solve the problem, and here's the point.

    Installation process of Windows 7 can not find any drive. I looked through the web a lot to solve this problem, even, without understanding.

    I read a lot of other people had the same problem. I tried different ways and I'm about to throw the laptop out the window.

    Is there anyone can help me?

    See you soon,.

  • During the installation of Windows 7 or 8.1 using a USB stick - get the message "cannot be installed, it is a GPT.

    Hello

    During the installation of Windows 7 or 8.1 using a USB stick - get the message "cannot be installed, it is a GPT partition.

    I have 64 bit install discs for Win 7 and Win 8.1. These two install on my desktop in duel boot. I made a Flash DRIVE of each disk so I can install it more quickly.

    Problem: I get the cannot install because it is a GPT partition.

    Y at - there no way to make these 2 USB sticks work?

    Thank you, Brad

    Make sure you create your media recovery HP or USB Flash Recovery discs before you edit or change anything.

    Your computer does not have Microsoft's Downgrade rights and you must buy a copy of Windows 7 with a valid Microsoft COA and product key.

    The screenshots below is from a laptop HP 15 t-j100... options and the configuration on your computer screens may differ.

    You will need to DISABLE "Secure Boot" and ENABLE "Legacy Support" in the "Configuration of the BIOS start-up secure" on the settings page similar to what is shown below, until you try to install Windows 7.

    After you save the changes, the computer will ask you to confirm the changes... Accept the changes by typing the four digit code and press the ENTER"" key.

    If you install Windows 7 from a USB and see a message of "load a driver - a required CD/DVD drive device is missing", it's because as 'System Configuration' > 'Config USB3.0 in pre-start' is set to 'Enabled '. This should be set to 'Auto '.

    In addition, as the factory hard drive is partitioned as TPG, you must start using the internal CD/DVD UEFI or UEFI-Key/key USB to install Windows on a GPT-partitioned disk. Turn on or restart the computer and press "F9" or "ESC", then "F9" when prompted. Select the source of boot UEFI you use and you press "ENTER".

    I suggest using Windows 7 SP1 for the best installation experience. If the DVD does not start as UEFI, you may need to use a USB Flash drive (can ask "Quick start" DISABLING in BIOS) as the installation media. Please note that some computers may not recognize a valid active UEFI USB Flash drive if it is formatted in NTFS and may require only a FAT32 formatted USB Flash drive. You should be able to make a FAT32 formatted Windows 7 installation USB Flash drive using Rufus, UNetbootin, Universal USB Installeror WiNToBootic. I like Rufus, because it contains options for 'Plan of GPT partition for UEFI computer' and 'FAT32'.

    If you have any other questions, feel free to ask.

  • Windows 8 not to recognise or install USB devices

    Windows 8 will not recognize any device I plug.  Some devices operate independently of not having a driver installed as my Passport external hard drive and printer Dell.  I've tried three different USB, Sony, Cruzer Mini and Cruzer Ultra jump readers, all are not recognized, and I can't manually install drivers (if they exist for Windows 8) on these, or any other devices.  I also have a HTC 8 x Windows phone which she also does not recognize.

    I tried many solutions, including:

    • Uninstalling in Device Manager and reinstall
    • With the help of 8 all of my USB ports, including 3.0
    • A clean boot and install
    • Manual installation of the driver - device manager does not recognize the driver on my hard drive
    • Re-the drive mapping (to jump readers) - they do not appear on Drive Manager to remap
    • Reset the BIOS

    I'm at my wits end here.  I don't know how Windows 8 will not recognize anything, or that it doesn't seem to be a reasonable solution!  Help, please!

    Hi Matt,

    I apologize for the delay in responding to your request.

    In order to detect any what equipment connected to a port on a computer, Windows is based on the drivers or firmware that controls those ports. After reading your description, I think that 'all' the USB ports on your computer are unable to read the devices that you have mentioned and you already reinstalled all your drivers. Please let me know if it is otherwise.

    At this point, the problem seems to be caused by a lack or an incompatible driver. You must first with the computer or motherboard manufacturer to verify if a Windows 8 compatible chipset driver is available for your computer/motherboard model. If no Windows 8 compatible chipset driver is available, try to install the drivers for Windows 7 in compatibility mode in Windows 8.

    This is how you run a setup in Compatibility Mode:

    1. download the installation file, right-click on the file and click on Properties.

    2. click on the compatibility tab.

    3. Select the compatibility mode that you want to apply, and then click OK.

    4. then run the installation using the downloaded installation file.

    Let me know the status of the issue once you have installed the appropriate Chipset drivers. If you are not able to determine which driver you should install, let us know your computer or the name of the manufacturer and motherboard model number.

    Thanks and regards-
