Hi Gilson,
Can you be more explicit about how CVI "cannot locate the port of this card"?  Because the card is not a National Instruments card, it will not be available in MAX and you will have to make direct calls to the Agilent drivers to do communication.  I am sure that Agilent exports functions to make programming the card from C (CVI is an ANSI C enviroment) possible.  Refer to the user manual for the card for more information.  
Hope this helps,
