Смотри MSDN KB article Q259697:
HOWTO: Force Reenumeration of a Device Tree From an Application
http://support.microsoft.com/support/kb/articles/q259/6/97.asp

- --- cut ---
The following code snippet shows you how to reenumerate the entire
device tree. This is the programmatic equivalent of clicking the Scan
For Hardware Changes menu item in the Device Manager.

BOOL ScanForHardwareChanges()
{
    DEVINST     devInst;
    CONFIGRET   status;

    //
    // Get the root devnode.
    //

    status = CM_Locate_DevNode(&devInst, NULL,
                                  CM_LOCATE_DEVNODE_NORMAL);

    if (status != CR_SUCCESS) {
        printf("CM_Locate_DevNode failed: %x\n", status);
        return FALSE;

    }

    status = CM_Reenumerate_DevNode(devInst, 0);

    if (status != CR_SUCCESS) {
        printf("CM_Reenumerate_DevNode failed: %x\n", status));
        return FALSE;
    }

    return TRUE;
}
