    In Device Manager under both x86 and x64 there is one item listed under Unknown Devices.

    Everything I have, both internal and external, seems to be working properly and listed under the
    various categories of Device Manager as working correctly.

    Is there any way to determine what this device might be?

    My computer starts, restarts, turns off, sleeps, and hibernates correctly.
    Might this be a component of the motherboard?

    Quite possibly the Game Controller on your sound card.

    No Game Controller on my sound card (Creative XFi)
    The Enumerator on the Details tab is ACPI
    Cannot recognize any on the other items on the Details tab
    Have searched Microsoft.com for some of the strings listed and can't find anything
    I thought it might be the Sleep button on my keyboard, but it works correctly

    Darrell,

    Details tab Hardware ID (Vista):
    ACPI\AWY0001
    *AWY0001

    In XP Device Manager, View, Devices by Connection, ACPI Multiprocessor PC, Microsoft ACPI Compliant
    System

    There is an entry for MS ArACPI Driver that is not in Vista x86 or X64 with the same
    Hardware ID:
    ACPI\AWY0001
    *AWY0001

    Regards,

  7. Only YOU know what is physically installed in your computer and what is not
    working as it should.

    In my case, the modem is not being detected (unidentified) and is therefore
    unusable.

    Not sure of that, but searching Google using

    PNPB02F

    brings up lots of things. looks like it could be a joystick port?

    If you open the properties of the unknown device under the Details tab there
    should be a dropdown box with Hardware IDs

    What are the numbers/letters after VEN_ and DEV_

    for examlpe VEN_109E&DEV_036E

    about 60-70% of the time a google search of these two feilds will tell you
    approximatly what it is.

    After a quick search I found this on google...

    Device Properties:
    Driver Description Standard Game Port
    Driver Date 23/09/1998
    Driver Version 5.0.0.0
    Driver Provider Microsoft
    INF File gameport.inf
    Hardware ID ACPI\PNPB02F
    PnP Device Game Port Joystick

    listed driver is for XP but game port drivers are generally generic you
    should be able to add a manual driver for it.

    On my 939 motherboard the unknown device went away after installing some
    driver from the manufacturer. (some nvidia PCI root driver). It doesn't seem
    to have any useful function (correct me if I'm wrong please).

    ACP sounds like ACPI?

    *AWY0001

    *That* unknown device I recognize -- it was in all the builds up toand
    including 5744 and I *think* it is in the RTM but I "upgraded" from 5744 to
    6000 after I had already "fixed" it.

    As far as I know, the error is harmless. If it annoys you, as it did me
    (lol), follow this link to the AMD forums:

    http://forums.amd.com/index.php?showtopic=80556

    and then download:

    ftp://ftp.asus.com/pub/ASUS/mb/socketAM2/M2N32-SLI%20Deluxe/AMDLive.zip

    The (supposedly) harmless unknown device error will go away. I do *not*
    think AMD Live gets enabled. AMD (and ASUS) still have some developing to
    do.
