Declaration

function RefreshDevices() : Boolean;

Example

// Refresh the list of devices
procedure TfrmMain.RefreshDeviceList();
var
  I: Integer;
begin
  lbxObjects.Items.Clear;
  if fPortableDevices.RefreshDevices = False then
    raise Exception.create( 'Unable to get devices: ' + fPortableDevices.LastError );

  lbxDevices.Items.Clear;
  for I := 0 to fPortableDevices.DeviceCount - 1 do
    lbxDevices.Items.Add( fPortableDevices.Devices[ I ].ID );
end;
