    I have a bit of a problem with WinXP telling me that one of my USB
    devices would operate faster if it was connected to a Hi-Speed USB 2
    port. But it does not ID the device in question. How do I figure out
    which device it is referring to? It does not happen all the time,
    maybe once or twice a day, so it's hard to pin-point.

    I've attached screen copies of the messages, if that will help ID the
    source. Any thoughts are appreciated.

    Thanks

    Attachment dropped. Probably too big.

    Open Device Manager, by clicking Start, Run and in the box enter:

    %SystemRoot%\system32\devmgmt.msc

    Click OK.

    Do you see any red Xs or yellow ?s in the list? Those are problems
    that need to be fixed.

    Now expand the Universal Serial Bus controllers section and look for
    the words:

    Enhanced Host Controller

    Enhanced is the key word which means high speed. If Enhanced is not
    listed, it is just a USB 2.0, but not high speed but a driver upgrade
    will usually fix it. You can get updated drivers from the
    manufacturer of your motherboard, although the Windows drivers will
    sometimes work.

    Right click one of the USB devices, Properties, Driver, Update and let
    it search Windows for a driver first. Be sure to reboot after making
    any changes.

    Sometimes there is a setting to change in the BIOS. In the BIOS under
    a section for USB, there may be an option for ECxx (enhanced
    controller) that is disabled. Enable it, reboot.

    After the update, there should now be at least one USB Enhanced Host
    Controller.

    It is possible to configure a check box in the properties on the
    device to never warn you about errors. Probably not a good idea.

    To create and post a screenshot:

    Press the Print Scrn button to copy your entire screen to the Windows
    clipboard.

    Press Alt Print Scrn to copy just the active window to the Windows
    clipboard.

    Open MS Paint:

    Start, Program Accessories, Paint

    When Paint opens, press CTRL-V to paste the clipboard, save the new
    Paint file to your desktop or someplace you can remember. JPG files
    take up less hard disk space than BMP files and just as readable.

    Make as many screenshots as you need. Practice makes perfect. Be
    careful your screenshot does not contain any personal information.
    Practice viewing your images before you upload them to be sure they
    are okay.

    You cannot upload a screenshot here.

    If there is no such function in your message board to upload files,
    then use a free third party image hosting WWW site.

    Create a free account on some free picture hosting web site. You can
    always remove your account later if you want. Here are some free
    image hosting sites:

    http://www.imageshack.us/
    http://photobucket.com/

    Using your free account, upload your screenshot(s) (the JPG or BMP
    files) to the site and it will return to you a URL web address (a
    Direct Link) for your new image(s) which you can paste the Direct Link
    in a message post, email, etc.

    When you are done, what you post for others to use should look
    something like this:

    Here is a better example of what you need to see when it is working
    properly:

    There are two sides to the story.

    The other posters have pointed out, that the motherboard "host"
    presents its capabilities, as entries in Device Manager.
    If there is an "Enhanced" entry in Device Manager, that
    logic block supports USB2 rates on a number of motherboard
    ports.

    The other side of the picture, is the "peripheral" plugged
    into the motherboard port. It has capabilities too. In
    the config information coming from the device, is a
    capability field that says the device supports USB2 rates.
    That might be the trigger, for getting a "helpful hint"
    from your copy of Windows.

    To check the plugged-in peripherals, try the UVCView program.
    UVCView was written my Microsoft, but is no longer available
    for download. Copies of the program used to be stored on
    archive.org, but Microsoft had those removed as well. The
    following two links are all that is left.

    *******
    ftp://ftp.efo.ru/pub/ftdichip/Utilities/UVCView.x86.exe
    http://www.users.on.net/~fzabkar/USB_IDs/UVCView.x86.exe

    File size is 167,232 bytes.
    MD5sum is 93244d84d79314898e62d21cecc4ca5e

    This is a picture of what the UVCView info looks like.

    http://www.die.de/blog/content/binary/usbview.png

    Some information on the parameters seen in UVCView.

    http://www.beyondlogic.org/usbnutshell/usb5.htm
    *******

    In your case, it could be that any peripheral with
    "bcdUSB = 0x0200" could be stating it is USB2
    capable. If the host port it is connected to, only
    is currently capable of running USB 1.1 rates, then
    you'll get the warning message in Windows. Once you
    get the driver installed, so the motherboard port will
    support USB2 rates, Device Manager has the "Enhanced"
    USB entry, then you may find the warnings stop.

    When using UVCView, the USB peripheral should be
    plugged directly into the motherboard USB port. I don't
    think the various USB viewer programs, have the capability
    to display entire USB trees, and typically only support
    things directly connected to the computer. The reason for
    this, is the basic code was "sample code" provided by
    Microsoft, and is not an attempt at a fully functional
    diagnostic tool. It is only a start, at the components
    of such a tool.
