Windows 7 upgrade now USB ports not working 82810 G (ICH7 Family) USB Universal Host Controller 27C9 and 27CC have errors in device manager

    Question

  • I upgraded from Vista Business x32 to Windows 7 Ulitmate x32. 
    My USB ports are not working. 

    When I plug in a USB Hard Drive, thumb drive or card reader, the device gets power from the USB ports, but the device is not installed, recognized or accessible in Windows.

    I get the error "Windows has stopped this device because it has reported problems. (Code 43)" on both:
    Intel(R) 82801G (ICH7 Family) USB Universal Host Controller - 27C9
    Intel(R) 82801G (ICH7 Family) USB2 Enhanced Host Controller - 27CC


    I've tried updating the drivers from 6.1.7600.16385.  Windows says these are the most current drivers.
    When I uninstall the drivers and reboot my machine there is no yellow ! error message until I try to plug something in, then the error message appears.

    I have a Gateway E155-C.  2GB RAM, Intel GMA video.  945GM chipset.

    Thank you in advance for your help.

    I tried this hotfix http://support.microsoft.com/kb/976972
    It updated my drivers from 6.1.7600.16385 to 6.1.7600.16445
    But the problem is still exactly the same, USB ports not working:
    I get the error "Windows has stopped this device because it has reported problems. (Code 43)" on both:
    Intel(R) 82801G (ICH7 Family) USB Universal Host Controller - 27C9
    Intel(R) 82801G (ICH7 Family) USB2 Enhanced Host Controller - 27CC

    I then plugged a keyboard & mouse into my USB ports.  They were recognized by Windows.  I unplugged these items and was able to plug in my USB HDDs, USB thumb drive, USB card reader and it recognized all of them. 

    Not sure how or why this worked, but I hope it helps someone.
