USB does not errors

Hello

I hope someone can help.
I have a toshiba satellite computer laptop with Vista. The laptop has only 2 USB ports, which stopped working. No indicator error in Device Manager. Just a long list including:
Intel(r) ICH8 Family USB Universal Host Controller - 2830 until 2836
Universal host controller Intel(r) ICH8 Family USB - 283 has
USB root hub figure 7 times.
When I plug a USB key that works on another computer, my laptop for example does nothing, as if I don't have whatever it is inserted in, no response at all.
I tried to unplug and remove and reinsert the battery.
They are dead, or is it repairable. Answers appreciated.

  • USB does not not on my HP DM4-1265DX

    Recently, I had my motherboard replaced by Geek Squad to the laptop and now my USB does not work

    The two 2.0 do not work with any Plug that I put in my 3.0 only works with any type of USB. I tried to uninstall and updated the driver, updating the BIOS, check if the port was clean, reinstall Window (which was a pain waiting), reset the CMOS, reset the default Bios and see that I can't access the menu in Advance on my HP Pavilion dm4 because it doesn't have this option to unlock. Thanks in advance!

    Hello

    You did most of the troubleshooting of your end steps steps only takes a few steps are updated Bios and recovery. If you still have the same problem as you informed that Mottherboard has been replaced you must bring it to the Geek squad and have it checked could be the cause of the motherboard.

    To run all the applications of the laptop or install download applications works does not error message indicating that the application is not valid "win32.exe or win32.application.

    Hello m.velentino,

    Not sure if you are still having the error message isn't valid win32.applicaiton.

    Get the error: not a valid 32-bit application can have several origins:
    I have listed some of them below.

    The file is corrupted, bad or missing.
    -If the hard disk is damaged or hurt it cause work programs to fail, either because not all data can be read from the hard drive the program is damaged on the drive. Run scandisk and defrag on the hard disk to check for potential errors.
    -If you run the program from a shortcut on the computer, verify that the program is still on the computer. In some cases if the program is no longer installed on the computer, you can get this error.

    File is not designed for your version of Windows:
    -If you try to run a program that is not designed for your version of Windows, you can get this error.
    -Although many old programs designed to work in older versions of Windows will work with new versions of Windows, unfortunately, not all programs will not work.
    -If the program is an MS-DOS program more former start program or Windows, you can get this error.
    -If the program is designed for a 64-bit version of Windows and you are running in a 32-bit version of Windows, it will not work and generate this error.

    File is a virus, worm or other malicious program file.
    -
    This error can be generated by a file that is a virus, worm, Trojan horse or other type of malware file. Often, this will result because the antivirus installed on the computer will not allow the file to install or run. Try to analyze the file to check, it is not a virus or infected.
    -If the file has been checked and is clean, it is always possible that the virus protection program or a another program installed on the computer is at the origin of questions during installation or execution of the program. Start the computer in Mode safe and try to run the program. start the computer in Mode safe will be that nothing is running in the background that could cause this problem.

    Hardware incompatibility.

    -If you get this error during the installation of a program, it is also possible that the CD-ROM drive or the drive that you are installing the program from is not compatible with Windows or has drivers that are not compatible with Windows.
    -Download the latest drivers for your CD player or other of the manufacturer of the computer or the manufacturer of the equipment. (Microsoft does not pilot for other materials)

    Recently, addition of windows 7 Home premium stopped detecting my garmin unit. Other USB devices such as my ipod work very well. I was able to detect the Garmin only a few times, he would try to install the drivers, but the drivers would not install. The garmin was working a few weeks ago. Here is a list of what I've tried:

    1. Reset (after all what I try)
    2. Turn off the computer and leave it unplugged overnight
    3. Completely uninstall all the drivers and the software associated with the kid.
    4. manual installation of drivers
    5. uninstall the unknown device and search for new hardware
    6. uninstall the unknown device and do a search for legacy hardware (which produces a device does not not (Code 10) error)
    7. Go back to a restore point before updating the last windows

    Please, any help would be much appreciated. I'm decently computer savvy and have always been able to solve any problems that I have. This one had turn me my wheels for days.

    Thank you

  • IEEE USB does not

    I using LV9.0 and used and converter ICS USB_IEEE. The work of ICS USB for a while then shut himself up. So I thought that I would go to an NI USB-IEEE. I reintalled the newest 488 OR drivers then reboot. The NOR-IEEE would work with Automation Explorer but it will not work using labiew or and LV .exe. I tried to do a simple writing IEEE - reading VI and it still does not work. (0) error. I then uninstalled ICS completely and installed the drivers OR-488 still and always does ' t work. Any ideas?

    Yes, I could send and receive data in MAX. To get it working again, I installed driver IEEE using the windows add/remove function. I then reinstalled driver. Now it's working. Do not know if my previous install driver wrote on a DLL that was bad but uninstalling and reinstalling solved the problem. Thanks for your help

    Hi Ali,

    Thank you for the update.

    I suggest you to run the next Fixit and check the status.

    Automatically diagnose and solve problems with the equipment. (USB) Keyboard and mouse are not detected by the Manager of devices or when they do not work.

    What it fixes:

    • When you install a hardware device, it is not detected
    • Determine if your audio device is plugged
    • The driver updates are not installed automatically by Windows Update
    • You receive one of the following errors:

    Click on run Fixit.

    Please let us know the State.
