1,It is not a NI USB-Serial Convertor.
2,Unplug USB-Serial Convertor Cause Computer dead.

1, Windows Boot with USB-Serial converter Plug in,this serial port
does not work.In MAX-Devices And Interfaces, see a yellow ! mark on
that com port.
After plug out and Re-plug in the converter,this com port work.why?

attached to it? If you remove the convertor you are yanking a COM
port out from under LabVIEW and this results in an unhappy
application. I do not know
