static int GetPhysicalPort()
    {
        try
        {
            devices = new List();
            
            ManagementObjectCollection collection;
            using (var searcher = new ManagementObjectSearcher(@"Select * From Win32_PnPSignedDriver WHERE DeviceId LIKE 'USB\\VID%' AND Description = 'USB Mass Storage Device' "))
            {
                collection = searcher.Get();
                searcher.Dispose();
            }
                

            foreach (var device in collection)
            {
                devices.Add(new USBDeviceInfo(
                (string)device.GetPropertyValue("DeviceId"),
                (string)device.GetPropertyValue("Description"),
                (string)device.GetPropertyValue("Location")
                ));
            }

            collection.Dispose();
           
            string LastAdded = devices[0].Location.Substring(6, 4);
            Console.WriteLine(LastAdded);
            return Convert.ToInt32(LastAdded);
        }

        catch (Exception e)
        {
            Console.WriteLine(e);
            return 0;
        }
    }


 class USBDeviceInfo
{
    public USBDeviceInfo(string deviceID, string Description, string location)
    {
        this.DeviceID = deviceID;
        this.Desc = Description;
        this.Location = location;
        
       
    }
    public string DeviceID   { get;}
    public string  Desc      { get;}
    public string Location   { get;}
}

I am using this Method to take the slot you are asking for. In fact I take the slot of the last plugged in USB due to the requirements I have. You can just debug and see the content of the class USBDeviceInfo and then use it for your own purpose.
