How do I detect when a particular USB device is plugged in?

[TusharD]

Hi,

I am writing an application that communicates to an external device using a USB port. I am able to access and manipulate the device from within CVI. Right now, I have to manually select the COM port to which the device is connected. Is there a way for the application to automatically detect the COM port?

Thanks !

Hello TusharD,

In your post you mentioned that you are using a USB port, and you also mention COM port. Typically COM ports are used to name Serial Communication Ports. Are you using a USB to Serial converter, perhaps?

Assuming it is serial communication, there is no built-in tool to see what is connected to each COM port. The VISA Find Resource VI will give you a list of available VISA resources which will include any serial ports.

Hope this helps, Cheers.
