  I am using Visual Basic Express 2008.  Is there a way to check each USB port for device captions(description) and then when the device is found, connect to that device?

  I have an application that uses 2 USB devices; I currently have to tell the programme which port each USB device is on; for example by using the line Device.Device_Connection(12) in the main class:

  Class Device

  Function Connection (ByVal COM_Port)

  SerialPort.PortName = "COM" & COM_Port.To String

  SerialPort. ect ect   .Open()

  Problem is..by nature of the application...these ports keep changing (the devices are the same) 

  Is there a way that the status of every port can be automatically detected, for example.. For Each port: check device ID or caption, if caption is the Required Device then connect to that port? 

  I think that this may be done by accessing WMI or with the My.Computer.Ports statement however I am unsure how to go about using these?

   Any advice or pointers recieved with thanks
