    USB ports not working

    using a Toshiba L500 laptop with Win 7 Ultimate 64 bit CPU Two USB ports

    Mouse works in both USB ports. Extrenal Hard drive nor Thumb drives are not recognized in either port.

    uninstalled all USB controllers. let windows reinstall USB ports inserted thumb drive it was recognized
    but said it needed new drivers.

    I looked on Toshiba support site - No Usb drivers listed.

    Where would I find new drivers?

    Thanks for your help.

    What manufacturer are the thumb drives? I wonder if the manufacturer site would have drivers.

    Try looking into updating the "chipset driver", or perhaps a reinstall of it.

    USB 2.0 drivers will be included in the chipset package. USB 3.0 drivers will be a separate download and install package.

    I would recommend that you remove your email address from the first post. It's never a good idea to post your email address on a public forum.

    Three are from Kingston. I reformatted one of the Kingston drives still was not recognized
    one from sandisk all fail to be recognized

    Thumb drive is seen in Device manager.

    Talked to Kingston Technical support. They said drivers are part of Win 7 OS.

    Suggested I run computer repair from Win 7 CD . That did not repair anything.
    Tried to do custom upgrade. Told that the installed OS was later version than on the OS on CD. Do I need to uninstall SP1 and all the updates??

    No need to uninstall SP1 to do a repair install. You can download the relevant Win7 installation disc with SP1 integrated from

    This may be too obvious, but I may as well post it anyway. Did you reboot? I almost never reboot my own laptop, just let it go into sleep mode and then wake it up. Turns out there is a Win7 bug which can sometimes prevent your USB ports from waking up. There is a registry change you can make to avoid this issue detailed in this MS technote : http://support.microsoft.com/kb/928631

    It is for Vista, but applies to all Windows OS. Or you can just reboot to see if the USB ports are once again recognized.
