List available COM ports

Question

I have a very small code that shows available COM ports.

My question is:

Is there an easy way to have the program to run in the tray and only popup when a new COM port is available and is it possible to add the name for the COM port that you can see in device manager ec "USB serial port"?

I often add/remove a USB->RS232 comverter and find it a pain in the ass because I must go into the device manger to see what COM port it is assigned to. It's not the same each time

Maybe there already is a small app that can do this but I havent found it on Google yet

using System;
using System.Windows.Forms;
using System.IO.Ports;

namespace Available_COMports

{
    public partial class Form1 : Form
    {
        public Form1()
    {
        InitializeComponent();

        //show list of valid com ports
        foreach (string s in SerialPort.GetPortNames())
        {
            listBox1.Items.Add(s);
        }  
    }

    private void Form1_Load(object sender, EventArgs e)
    {
    }

    private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
    {
    }
}

}

Take a look at this question. It uses WMI to find available COM ports. You could keep track of what COM ports exist, and only notify about new ones.
