    I have a USB printer and a USB digital camera. The camera doesn't get recognized.
    I get the error code 38. Windows cannot load the device driver for this hardware because a previous instance of the device driver is still in memory.
    I tried the simple restart and no luck.
    I can however uninstall it, and go to the add hardware wizard and get it to work, But......
    then the printer doesn't work.
    I have to go and uninstall it and add it in the hardware but then the camera doesn't work.

    Any clues?????

    Wow, THAT is a strange problem. I can see that being absolutely infuriating!

    Any conflicts in your device manager? Please post your system specs with operating system up to the service pack level.

    Dell Dimension 4400
    1.8ghz
    1GB Ram
    60GB HD
    XP Home SP2

    I might try buying an extra USB card. The Dell only has 2 in the back and 2 in the front. I tried both front and back. One in the front one in the back and still nothing.

    Sounds strange, but then again it is a Dell. Im not sure what that problem is more than likely it is a Known issue with your motherboard. Ill look in the Dell Database when I go to work on Friday. Ill post if I find anything.

    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.
