I'm having the same problem as originally described, except I also get the same error message "Insufficient location information or the device or resource is not present in the system" when I try to "Open VISA Test Panel" in MAX. I checked the Device Manager and there is one Serial port listed, but its properties say "Location: Unknown". How can I get Windows to recognize the serial port?
It would have probably been more beneficial to start a new thread as this problem is a bit different. Anyway, we can continue here. Can you attach a screenshot of your COM port in Windows Device Manager and NI MAX?
It should show up in MAX under Devices and Interfaces>>Serial and Parallel
Pablo, I did not mean to be hostile, but mainly offer the advice for your future posts. You usually want to reply when you are building upon the original post. While it is great that youfound this post, and ruled out this as a possibility, I would have started a new post and linked to this one stating you have seen it and it was not helpful.
Hope that helps, looking forward to helping you out!
