    Specs: Windows XP Home, Dell (POS) Dimension 2400

    I'm at the end of my rope with my computer. I've been able to deal with the annoying quirks (software randomly deciding to never work again, ect) but now it's gone over the line.

    My USB ports won't recognize anything. Or, it will recognize it, but then refuse to do anything. It's happened with my plug-n-play Pentax camera, and more recently my brand new iPod. My older cameras and mp3 players are recognized correctly, and show up with the light gray and lime green icon in the taskbar. The new devices show up with the strange green/brown/silver icon as "Found new Device - Camera" or "Found New Device - iPod" and then it just sits there. Restarts have done nothing, uninstalling and reinstalling software has been a waste of time.

    Help me out before I kill this machine.

    Hi I may be able to help, if you could go ahead and pm me your service tag for your computer so I can look up your specs in the Dell database and see what hardware/mobo you have.

    First step, Start, Programs, Accessories, System Tools, System Restore. Create a restore point and name it something like "Before USB Fix". This is to bail you out if something goes wrong during the following process and makes things worse.

    Create a file with NOTEPAD containing the following lines and save it as FIX.REG

    -------------------------- Use text after this line --------------------------------
    REGEDIT4
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment]"DEVMGR_SHOW_NONPRESENT_DEVICES"="1"

    -------------------------- Use text 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.

    NOTE: If you have a USB keyboard and/or mouse, you'll have to modify the instructions and leave enough parts for those to function. I don't have one yet, so I haven't had time to modify the instructions.
