Hi undergraduate,

the first post shows how you can get the event if a new USB device was attached. If you need the available COM Ports, then you can use the "VISA Find Resource" function.

Hi undergrate,

where do you have problems with it? If you use it, you'll get a list of found devices.

Hi undergraduate,

what is your problem with this function? Is the help not self-explaining?
