    When we plug a new device into USB, windows will show the found new hardware
    wizard. When we cancel it, it shows a baloon notification that the device is
    not configured properly. But the device will be shown in yellow ? mark in
    device manager. i need to search for an unconfigured device shown in yellow ?
    mark in Device Manager and delete it programatically using VC++ (the same
    thing we do by rightclick and uninstall in device manager). I googled and
    found that SetupDiXXX API's are there to do device management functions. But
    i'm not sure which API's to use, MSDN having only limited documentation. I
    have Device's Name( the name which is listed in devicemanager) so i need to
    find using that name. please do help me doing this..., its an urgent
    matter... Thanks in advance

    Yes, use SetupDiXXX API.
    You can find devices with yellow ? and other install problems by
    quering SetupDiGetDeviceRegistryProperty SPDRP_INSTALL_STATE.

  3. you do realize that uninstalling the device will not matter b/c as soon as
    the usb bus rescans (due to any change or the user asking for it), it will
    show up again and you will see the same process with the pop up and the ?'ed
    device. i think what you want is to disable the device, which will persist
    across reboots and rescans and the user will not be notified again until it
    is enabled

    The best source of sample code for the SetupDi functions is the "devcon"
    tool in the DDK/WDK. I don't know whether this exact case is covered, but
    you'll see the general philosophy.

  6. can you provide me a sample? i'm tired of searching for a sample on
    this topic. i found SetupDi API's which helps me uninstalling an
    installed driver but not removing unknown and not-installed device in
    yellow question mark. thanks in advance

    Sorry I can't. Also, Doron is right, maybe what you actually need is
    disable the device.

    (A side note: having unusual requirements often indicates going to a
    wrong direction ... )
