USB Universal Host Controllers - Windows 7 Ultimate edition. Does not properly

All my computer controllers USB universal host will not function properly. How can I solve them?

Hello

1. ask at any USB or external drives worked on your computer?

2. What is the brand and model of your computer?

3 do you receive error messages when connecting USB devices to your computer, or in Device Manager?

4. is any device USB detected or can be displayed in windows Explorer?

Please follow the steps below and check if that helps.

Method 1: My drive does not appear in Windows Explorer

http://support.Microsoft.com/kb/330140

Method 2: Uninstall and reinstall the USB drivers

As all associated drivers, USB devices the same facilities also have it. Sometimes proper drivers are not detected after initial installation for the reinstallation of the drivers solves the problems.

You can check after uninstalling and reinstalling USB drivers if you are able to connect. You can disconnect all USB devices and then perform the following steps:

(a) click Startand then click Control Panel.

(b) click system and Maintenance, click System, and then click Device Manager.

(c) Note if the control panel is in Classic view, double-click Systemand then click on Device Manager.

(d) If you are prompted for an administrator password or a confirmation, type the password, or click allow.

(e) in Device Manager, double-click to expand the "USB Bus controllers", right click on the controller host, click "Uninstall" and click "OK".
Check that if at all, there is an exclamation point on the pilot, it suggests problems with the installed driver.

(f) repeat step 2 to uninstall all items under 'USB Bus controllers'.

Then, restart your computer and Windows 7 will automatically reinstall all USB controllers.

If the edge of the issue persists, I'll ask allows you to check the chipset driver updates, you can get on the site of the manufacturer. The chipset drivers normally integrate USB controller drivers as well.

I hope this helps.

  • Windows 7 Starter Edition does not recognize a hard drive WD

    Windows 7 Starter Edition does not recognize a hard drive WD, I used until last month. Device Manager sees it, he sees the USB controller (it lists as a mass storage device), but I can't access the information on the hard disk, or make use of the last backup. I tried to uninstall USB drives - it is not the thing. It gets listed under disk drives.

    Thanks for the reply.

    There was no error message: the device has been recognized (listed) by the USB controller and the Device Manager, but not by the management of the disks - so I couldn't access.

    I managed to fix the problem after:

    -J' scanned the computer (DELL Inspiron) with the Safety Scanner
    -J' completely uninstalled all the software associated with an external hard drive
    -J' uninstalled the USB controllers
    -reboot the system
    -reconnected the external HD
    -After gaining access to the drive, I installed the dedicated software

  • Windows Vista Ultimate Edition will not be upgraded to Windows 7

    Windows 7 Upgrade says he cannot directly upgrade Windows XP, duh?  I ran the Upgrade Advisor before running the upgrade software and did not get this stupid message. I get only when the software upgrade performs its checks.  I am running Windows Vista Ultimate Edition with all updates to September 24, 2013.

    Which edition of Windows 7? It matches the edition of Vista you are trying to upgrade to?

    When important changes to your computer, for example an upgrade, it is always recommended that you back up your system before installing a new version of Windows. In your case, you can upgrade to Windows 7 depending on the edition and the architecture of Windows Vista, you have installed. If you are running a 32-bit version of Vista and upgrade to a 64-bit (Windows 7 edition) version, you'll have a pure make install, it is the opposite case.

    If you are using Windows Vista Home Basic or Premium consumer editions, you can only upgrade to Windows 7 Home Premium or Ultimate. In addition, you can make downgrades, which means, if you are running Windows Vista Ultimate Edition now, you cannot downgrade to Windows 7 Home Premium. You perform logical upgrades:

    Windows Vista Home Basic > Windows 7 Home Basic, Premium or Ultimate

    Windows Vista Edition Home Premium > Windows 7 Home Premium or Ultimate

    Windows Vista Business > Windows 7 Professional, enterprise or ultimate edition

    Windows Vista Business > Windows 7 Enterprise

    Windows Vista Ultimate > Windows 7 Ultimate.

  • Windows XP Home Edition does not load in any mode after reboot to uninstall Norton

    I wanted to get rid of Norton anti-virus, then, I have downloaded and run the Norton Uninstaller. After what seemed an eternity he finished and asked me to restart the computer to complete the uninstalation. I clicked the botton "Restart now" and after the screen, which shows the bios is nothing. No loading screen, no beeps or anything else, just black. In addition, it does the same thing in all modes.

    I removed the HDD and an IDE to USB for connecting to my mobile backup (Win7 Ultimate) and performed a virus with TrendMicro Titanium antivirus scan + and scan with malewarebytes paid version maleware. No virus or maleware found. So, I ran a check/repair through backup with no found error disc.

    I do not have a XP or 7 CD repair/install, nor am I money right now. I really need to get going again.

    You can also communicate with Compaq and request a repair disk.

The House of win 7 was already languages. Please guys help me how to fix my laptop.

    Well, you could have done your own recovery discs when you bought your PC!

    I agree that it is a shame that you can't get a copy of the disks where you live!

    If you are happy to have a cracked version of Windows, it is to you. Even if you can open a Pandora's box, we'll agree disagree on the question

    As for the problem of button, it could be a sign of a faulty keyboard or it could be a software problem. A few copies of cracking are so changed, it could be an error in the code!

    You can try and run a Linux live disk to see if it happens there. If so, then the keyboard will be replaced.

  • Satellite C660-108 - Windows XP Home Edition does not install

    I try to install Windows XP Home Edition on a Toshiba Satellite C660-108, without success.

    I changed the BIOS disk in "Compatibility" mode (what is the same thing as "Legacy IDE"?) by following the instructions on a Yahoo Answers question on the same issue.

    What has improved the situation, in what I now get an error message a few minutes after installing XP said "Starting Windows" instead of immediately after. The error message is the same that I have already received and is as follows:

    "A problem has been detected and windows has shut down to prevent damage to your computer...". "Technical information: * STOP: 0x0000007B (0xF78D663C, 0xC0000034, 0x00000000, 0x00000000).

    Thanks in advance for any help,

    Luke

    PS - I'm a mac user and do not have much experience in the use of Windows laptops, so I need instructions spelled out clearly enough if possible.

    The error could be related to drive HARD and the setting in the BIOS of the controller...
    Probably, you need to install Win XP using SATA AHCI mode and to add the driver SATA as described here:

  • Windows XP Home edition does not charge up - screen Toshiba and then nothing

    I opened my computer to stand by earlier. And received an error message such as:

    WINDOWS CANNOT CONTINUE RUNNING BECAUSE THE FILE IS DAMAGED AND UNREADABLE...
    Then he had a countdown until it restarted. After the computer restarted (loads of screen toshiba upwards) then nothing happends. I managed to get into the safe mode start page, but when I select start in safe mode, it does nothing, actually freezes. Seems that the problem is with XP.

    I also tried to "last good configuration" but who also refuses to load.
    I can, however, in the BIOS.

    The black and white background writes startup screen that flashes briefly upward when after that the toshiba screen doesn't even come to the top.

    I have a P100-429 Satilite using XP SP2 (or 3) does not remember.

    Is this a hardware problem? I lose data?

    I am aware that my system was clean and I was using a good anti-virus.

    Please please let me know if you have any suggestions or comments.

    Thanks in advance, Max...

    Hi RisSsky,

    you are in a deep deep sh... t... No. not really...
    Looks like the filestructure hard disk is damaged.
    the hard drive is recognized by the bios? means, it is listed as a device?
    There is a sound of the hard drive? scratch or buzzing or ticking?

    CHKDSK may help, but I would 'safe mode' where you want not to lose data on disk.

    don't panik, we will do things.

    2 options to solve this problem:
    the first and save:
    -Remove the old hdd (you need later)
    -get a new hard drive and make a recovery/installation on the new drive.
    -also get a usb - hdd connector to access old data hdd and copy on the new disk.
    or the 2nd:
    -run chkdsk on your hard drive, maybe you need to do this with a "live-system-on-cd.
    Be aware that if there is a problem it will get worse...
    -start in safe mode

    If you're lucky, the 2nd option will do.
    as said before I'd do it "the safe way.
