Windows raises events to tell you when a USB device is inserted and removed.

If you search for WM_DEVICECHANGE you should find many example, like,,

vb.net Code:

Public Class Form1
    Private Const WM_DEVICECHANGE As Integer = &H219
    Private Const DBT_DEVICEARRIVAL As Integer = &H8000
    Private Const DBT_DEVICEREMOVECOMPLETE As Integer = &H8004
    Private Const DBT_DEVTYP_VOLUME As Integer = &H2
 
    Protected Overrides Sub WndProc(ByRef m As System.Windows.Forms.Message)
        'check for the DEVICECHANGE message (Detects USB devices)
        If m.Msg = WM_DEVICECHANGE Then
            Select Case m.WParam.ToInt32
                ' if a device was added or removed then update usb drives list.
                Case DBT_DEVICEARRIVAL, DBT_DEVICEREMOVECOMPLETE
                    Dim DevType As Integer = Marshal.ReadInt32(m.LParam, 4)
                    If DevType = DBT_DEVTYP_VOLUME Then
                      ' DO SOMETHING...
                      '  Me.BeginInvoke(New Action(AddressOf GetPenDrives))
                    End If
            End Select
        End If
        MyBase.WndProc(m)
    End Sub
 
End Class
