    Hi,
    Can anyone help me out. I have a P4 PC running windows XP with SP2 installed but my USB ports won't pick up anything when I plug in my camera or iPod. Basically the USB ports aren't working. do I need to change a setting or enable them in some way?

    Do they appear without errors in Device Manager? If so, try this:

    Create a file with NOTEPAD containing the following lines and save it as FIX.REG
    -------------------------- cut after this line --------------------------------
    REGEDIT4

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment]

    "DEVMGR_SHOW_NONPRESENT_DEVICES"="1"
    -------------------------- cut before this line --------------------------------

    Double click on FIX.REG and say yes to the Merge Into Registry question.

    Unplug ALL USB devices.
    Open Device Manager.
    View, Show Hidden Devices.
    Uninstall all devices under USB Controllers.
    Uninstall all devices under Disk Drives that you know are not present.
    Uninstall all devices under Storage Volumes. Say no to any reboot prompts until you are finished. Also, if a Storage Volume doesn't uninstall, ignore it and move to the next one.
    If you have a yellow ? with unknown devices, uninstall all of the entries there as well.

    When this is done, reboot TWICE.

    Reconnect the USB devices and see if they're recognized properly.

    You might also check properties in the USB Root Hub entries in the Device Manager and make sure that this setting is unchecked:

    I tried that - no luck. I have a Code 1 Error (used to be a code 28 Error). I know what these are but I cant re-install the driver through the Hardware Update Wizard because the wizard "cannot find the neccessary software" when I try to install the software automatically. Its recognising the fact that I've plugged in a USB device, it just doesnt let me do anything with it.

    did you try to reinstall SP2 like I said ? but before you reistall SP2 backup your files can also mean you need to update your mobo chipset drivers or mobo bios
