Win32_SerialPort Class not working in Windows 8.1 Pro

Question

In Windows 8.1 Pro, the connected USB device list is not showing while USB device is showing into Device Manager(Control Panel).

 

I have a .NET 3.5 application, where I am using the following code to get the list of connected USB Serial Port device 

ManagementObjectCollection collection;
using (var searcher = new ManagementObjectSearcher(@"Select * From Win32_SerialPort"))
{
    string paytmUPIPort = "";
    collection = searcher.Get();
    foreach (var serialDevice in collection)
    {
        paytmUPIPort = string.Format("{0}", serialDevice.GetPropertyValue("DeviceID"));
        if(paytmUPIPort.ToUpper().Contains("COM"))
        {
            collection.Dispose();
            return paytmUPIPort;
        }
    }
}
collection.Dispose();
