Win32_SerialPort Class not working in Windows 8.1 Pro

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();
