    hi guys,

    i have a clone box...horrible thing!!! it had a power supply that blew...and i replaced the power supply
    then it was freezing after a few minutes of operation...truly freezing clock didnt change

    i narrowed it down to the front usb ports...in fact none of the usb seemed to work...and yes...i did check in the bios
    and everything was enabled except legacy usb...but this didnt make a difference
    as soon as i plugged usb in it froze

    so i disabled USB and added a pci usb expansion card
    now im getting unknown device usb errors and the big black usb icon in the task bar.

    is the card still using aspects of the on board usb...or is it totally seperate...?
    do you think the card is gone too?

    any suggestions...please

    Do you have the latest Service Pack? You may need to update if you haven't

    Whether you have an expansion card or not, you still need to have USB enabled in the BIOS.

    Here is one approach to cleaning up and reinstalling the USB support. You will probably need to uninstall the USB Controllers and let them be reinstalled. Usually a couple of reboots are needed to complete it. You should remove ALL USB devices before doing this and temporarily rely on a ps/2 mouse and keyboard, especially if you have password protected the system. Otherwise you may not be able to log in until the USB ports are reloaded.



    To do this you have to first install a registry patch >> http://forums.techguy.org/attachments/100544d1173412107/usbghosts.zip

    Best to create a restore point before proceeding.

    Then once the patch is installed and with that USB device NOT connected open the Device Manger, and under "View" select "show hidden devices"

    Then drill down to Universal Serial Bus Controllers and remove the "ghosted" "code 45" entries (check the properties if you are unsure)

    There is a more complete procedure which involves uninstalling ALL USB devices, not just "code 45" ones but you MUST be using a PS/2 mouse and keyboard to do this, especially if you are on a password protected system.

    Yes it should -- but what do you mean "clean install"? Are you referring to the operating system or the expansion card?

    SP2 should have all the USB support you need and no further drivers should need to be installed -- even with the new card.

    Have you checked the Device Manager for errors under the USB device tree?

    You should be looking for the "Enhanced" drivers there

    In my 2nd screenshot you see the entry for a VIA enhanced controller card installed on my old Dell XP SP3 system. The drivers for this are the same as the other.
