I'm trying to run a LabVIEW program on older Window XP computers (small portable with display, bought 10 of them). I have a USB data acquisition device connected to an USB port.
The virtual serial port is not seen by VI. It does not show in NI MAX either.
But it shows in Device Manager.
It works fine on Windows 7.
Drivers are installed.
Works fine with a terminal program (Win7) .
What could be the problem?
Changing the name to "COM" in Device Manager, as some suggested, was not possible.
