    Unknown devices in device manager

    Hi All,

    I installed new software to use USB port to connect the board and program that board During this installation some things went wrong and all my USB port are not responding or not working at all...

    When i checked the Device Manager it shows like Other device -> Unknown device..

    I install the chipset from Toshiba download and still I canít solve the prob....

    my USB all port not working..
    my WiFi is not working..
    my Camera is not working...

    i use..

    Toshiba satellite L300-110 SYSTEM UNIT
    Model No: PSLB0E

    OS - Vista 32 Ultimate x86

    i try to update the driver for that unwknown device from Device Manager but it show the eorror like..

    windows found driver for your device but encounter an problem while attempting to install it..

    inter(R) ICH8 family USB Universal Host Controller 2834

    an error occur during installing of the driver

    The driver installing file for this device is missing a necessary entry. this may be bcz of INF was written for win95 or later, contact ur hardware vendor.. .
    .

    and also i check the Unknown device-> property it show error code (code28)....

    i uninstalled that new software and i try to install the chip set from Toshiba but no change...still it show the same error message as above....

    when i try to install the driver for camera inbuilt in system it stop installing and show error and exit the installation..

    as i installed lot of driver i dont have old restore point to restore my system too....

    i dont have backup for my system also...

    I would try a system restore to before you installed the new software.

    Since the software appears to have corrupted your system, restoring the system to before installing the software should fix that problem and give you time to investigate the problem with the software before trying to install it again.

    Are you saying you booted into Safe Mode; went to System Recovery and checked for older system restore points?

    Oh nutz... You have clicked the "Choose different Restore Point" correct?
    Then "Show Older than 5 days"?

    If you have, you're out of luck.

    If you haven't tried yet, I would uninstall your recent programs. Then in the hardware monitor, uninstall the USB devices.
    This might be best done in "Safe Mode"
