Hello All,

I am able to get the list of all USB drives into a dropdown.
But I only need the list of attached Pen Drives to a system only. I do not want to add the other attached devices to the computer. The devices like : Mobile phones, Camera, USB HDD, USB CD/DVD drive etc.

~~I need the solution ASAP, because I can not move to next step of my application without doing this.~~

Edit: here is the code

C#

try
{
    Cursor.Current = Cursors.WaitCursor;
    var drives = DriveInfo.GetDrives().Where(drive => drive.IsReady && drive.DriveType == DriveType.Removable).ToList();
    cmbDrive.Items.Clear();
    foreach (var dir in drives)
    {
        cmbDrive.Items.Add(dir.Name);                 
    }
}
catch (Exception ex)
{                
    MessageBox.Show(ex.Message);
}
finally
{
    Cursor.Current = Cursors.Default;
}

Please help me friends....

Thanks
Kapil

Please use "Improve question" to post your code so that it can display syntax-highlighted (already done this time ;-) ).

You can check device status by IsReady property of DeviceInfo for checking whether its attached and ready to use or not.
But IMO you cant fetch only pen drives because other devices like USB HDD is attached to machine than this will also be listed.
Code sample:

C#

DriveInfo[] allDrives = DriveInfo.GetDrives();
            foreach (DriveInfo d in allDrives)
            {

                if (d.IsReady && (d.DriveType == DriveType.Removable ))
                {

                }
            }

Hello All,

I am very happy to say you that I have done this task.

I am going to provide you the links which helped me to make it possible : [The links are really AWESOME ]

1) http://usbspeed.nirsoft.net/usb_drive_speed_summary.html

I got the list of USB and their VID and PID. Then I created a serialized list of the sorted list. I made some changes into the serialized list

2) http://emmet-gray.com/Articles/USB_SerialNumbers.htm

Go to the end of page and get the "USBView.zip".
