USB Mass Storage Devices Unrecognized (Vista)

    Hi all,

    It appears that I'm one in a growing number of people with this
    problem, so I figured I may as well jump in! I recently upgraded to
    Vista Ultimate and backed-up all my XP files (music, photos, etc.) to
    a brand-new Maxtor OneTouch III external USB drive. After installing
    Vista, the drive was detected as a mass storage device and worked like
    a charm (this was about a week ago); I've used it up until yesterday
    with no problem. I also have an iPod Shuffle and a USB memory stick
    that both detect as mass storage devices, and they worked fine as

    Yesterday, I went to burn a CD from some music files stored on the ext
    HD, only to find... none of those three devices listed in Explorer!
    Naturally, I tried unplugging and re-plugging the ext HD. After a few
    seconds, Vista says 'installing drivers for your device' and then 'usb
    device unrecognized' -- no dice. I tried unplugging, powering-down,
    and re-plugging the drive -- no dice. I even tried unplugging,
    powering-down the drive, rebooting the computer, then re-plugging the
    drive -- still no dice. It always tries to install some driver (no
    specifics given) and then fails to recognize the device.

    The closest I've come (and this is interesting) is by uninstalling the
    USB Controller device listed in Device Manager. Immediately after
    uninstalling, Vista detects all 3 of my devices and pops-up the
    explorer browser windows for each! I was stoked, until... 'installing
    new drivers', 'unrecognized device', *poof* they all disappear again
    from Device Manager and Explorer. So close.

    What have I done between the time those devices worked and yesterday?

    1. Extracted the GART driver from the Nvidia nForce 5.11 XP driver
    package and installed it (my FPS in games were absolutely horrid until
    I did this).

    2. Disabled indexing (for performance)

    3. Installed my 3rd gig of RAM (now running at 3GB RAM)

    4. Set my CPU to high performance in Power Options

    Here's my system specs:
    AMD 2800+, 3GB RAM, Asus K8N mobo (nForce3 250 chipset), GeForce
    7800GS OC AGP

    I've already installed all the Vista updates I can find, and tried all
    the power-off/on combos mentioned by everyone else. No, the ext HD
    doesn't appear in disk management nor explorer or device manager. I
    know my mobo is USB 2.0 compliant, and that all 3 devices worked only
    a few days ago without a hitch (eliminates faulty devices, power
    issues, etc.). I've found the following MS KB articles and will
    investigate more when I get home:,

    Any additional help/troubleshooting would be greatly appreciated!

    Here's what comes in the nForce 5.11 driver package (I only installed
    the GART driver):

    Audio driver version 4.42 (WHQL)
    Audio utility version 4.44
    Win2K ethernet driver version 4.16 (WHQL)
    WinXP ethernet driver version 4.16 (WHQL)
    Ethernet NRM driver version 4.82 (WHQL)
    Network management tools version 4.88
    GART driver version 4.36 (WHQL)
    Memory controller driver version 3.38 (WHQL)
    SMBus driver version 4.04 (WHQL)
    Installer version 4.46
    IDE driver version 4.46 (WHQL)

    I'm wondering... should I install the SMBus driver? I have no idea
    what it is, but perhaps it has something to do with USB devices? Could
    be bad though since they're XP drivers. I've read plenty of people
    installing the GART drivers on Vista with no problem, but nothing else
    from this package.

  3. I believe there is some sort of problem with Nvidia M/B's when it comes to
    installing 3 gig of RAM.

    I have an Asus A7N8X2.0 deluxe. Using 2 gig of RAM is ok. When I install a
    3rd 1 gig stick (matched) I have all sorts of problems.

    Did you install the most recent BIOS?

    Fabulous question! I'll have to check when I get home as to which BIOS
    revision I have installed.

    This is an interesting idea... but I can't seem to find any related
    posts/discussions about this topic. Do you have any links to resources
    and/or fixes for it? I could try removing the new memory this evening
    and see if it helps, but I'd hate to be stuck at 2GB forever.

    Apparently, everyone's saying that

    it tonight.

    I do not believe that this problem is either Nvidia chipset or 3GB memory
    as I face the very same problems with Intel made DG965SS motherboard and 2
    GB of memory. I have the latest BIOS (10th of May, 2007).

    This problem was somewhat common in XP, though I haven't yet seen it in
    Vista. When you plug in the device, do you get an opportunity to manually
    select a driver? If so, try pointing the search to the \WINDOWS\inf
    folder. If that works, see the ongoing fix under "XP asks for drivers or
    just want to install new hardware" in the link below.

    There is some other good information on that page for troubleshooting USB
    storage device problems. Although it is written for XP, most of it will is
    also applicable to Vista.
