Get RemovableMedia devices info using C#

I want to get detailed info about all removable media devices such as USB disk,Smartcard reader etc. and integrated devices such as Fingerprint reader,integrated camera etc on my Windows system using C#. If it can be done through WMI then please tell me detailded approach as I've tried querying "Win32_LogicalDisk" class but that didn't yield much helpful results. Also there is windows API "DeviceIOControl",can it help me much in this regard?

Did you check the below class?

  System.IO.DriveInfo

What detailed information are you looking for in addition to the ones provided by this class?

http://msdn.microsoft.com/en-us/library/system.io.driveinfo.aspx

You can check other classes in this namespace.

Edit based on the comment:

If you want to detect the device at runtime, you may use:

ManagementEventWatcher & WqlEventQuery

Below is an example:

WqlEventQuery _q = new WqlEventQuery("__InstanceOperationEvent", "TargetInstance ISA    'Win32_USBControllerDevice' ");
        _q.WithinInterval = TimeSpan.FromSeconds(1);
        _usbWatcher = new ManagementEventWatcher(_q);
        _usbWatcher.EventArrived += new   EventArrivedEventHandler(OnUSBDetectedOrDetached);
        _usbWatcher.Start();

and in the event handler:

void OnUSBDetectedOrDetached(object sender, EventArrivedEventArgs e)
    {
        ManagementBaseObject _o = e.NewEvent["TargetInstance"] as ManagementBaseObject;
        if (_o != null)
        {
            using (ManagementObject mo = new ManagementObject(_o["Dependent"].ToString()))
            {
                if (mo != null)
                {
                    try
                    {
                        string devId = string.Empty;
                        devId = mo.GetPropertyValue("DeviceID").ToString();
                        if (devId != string.Empty)
                        {
                            Trace.WriteLine("Detected USB Device, DevId: " + devId);
                        }
....
