My system is Window 7 32-bit

Labview 2011

I have a usb to serial device. After the device is plugged into the computer, window will show a usb-serial device. Without going to the device manager, is it possible to use Labview to scan to see what COM number the device is enumerated as?

I can use VISA  find resources to check the COM port. But if i have multiple COMs on the PC, how do i know which one is the one from my device?

thanks.
