Windows USB device refresh in C\C++

I am trying to find a way to programmatically re-enumerate the USB devices connected to the USB ports of a pc.  In windows XP, it is possible to open the Device Manager, right click on the PC name and select "Scan for Hardware Changes".  How can I execute this (or something similar but specific to the USB bus) from a C\C++ program?  MSDN website is not helpful.

Got it.
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;
}
