Windows 10 and WMI Query change

Question

0.00/5 (No votes)

See more:

I have been using a WMI Query to detect when a new device has been detected, in this case a USB device. A Bluetooth dongle that creates a virtual comport.

The WMI Query string is "Select Name, Status from Win32_PnPEntity" for the Plug and Play entity.

This works great for me except for Windows 10, it cannot sense that the device has been inserted and therefore removed.

I have done a search for any changes to these queries but cannot find anything.

Does anyone know where I can find a list of the changes between the different operating systems?

Thanks

I downloaded the WMI Code Creator and used it to get c# code for 'Win32_PnPEntity' using the name property.

In WMI Code creator lets you search for the property values for the name property and I did get a list for the USB device, however when I copied the code and put it in my program, it does not list the device that I want.

Both programs obviously run on the same OS and so I don't understand why it wont list the device in my program. The code below is what I extracted from WMI CC.

C#

using System;
using System.Management;
using System.Windows.Forms;

namespace WMISample
{
    public class MyWMIQuery
    {
        public static void Main()
        {
            try
            {
                ManagementObjectSearcher searcher =
                    new ManagementObjectSearcher("root\\CIMV2",
                    "SELECT * FROM Win32_PnPEntity");

                foreach (ManagementObject queryObj in searcher.Get())
                {
                    Console.WriteLine("-----------------------------------");
                    Console.WriteLine("Win32_PnPEntity instance");
                    Console.WriteLine("-----------------------------------");
                    Console.WriteLine("Name: {0}", queryObj["Name"]);
                }
            }
            catch (ManagementException e)
            {
                MessageBox.Show("An error occurred while querying for WMI data: " + e.Message);
            }
        }
    }
}

Any ideas what this could be?
