For the above explained application we are using NI USB-8451.
Now for reading the data , should i use VISA vis or DAQmx VIs.

A quick search of USB 8451 turned up the following links:

The last one has a link to the programming manual at the bottom.

Hello R,
No, you don't communicate with the USB-8451 using DAQ VIs; the 8451 has it's own driver (NI-845x), and the first link Dennis provided above will take you to the download page. Also, when you download the driver, you will find some shipping examples in the example finder, which will help you get started. Hope this helps. Thanks!

HI
How can we configure the spi frequency of operation for NI-USB-8451
I am developing a testing tool which requires the data to come from PC instead of a card reader which speaks to the testing device on spi.
however different card readers speak on different spi frequency and i need that to be configurable. Can this be done in lab view. And I need some more i/o signalling along with the spi. Is this possible.

The 8451 SPI frequency is set the "NI-845x SPI Script Clock Rate" VI. Check out Chapter 8 of the software manual.
In terms of "more I/O signaling" the 8451 has 8 general purpose digital I/O lines. This information is in the User Guide and Specifications.
