It's getting complicated... I can't find the device that you're talking. But let me resume:
1 - you've some sensors
2 - they are connected into a certain device that translates de analogue signal into a certain way trought USB
3 - this supplier MUST give you de driver so that you can understand what you're receiving on the USB port
4 - after all of this, you can use it on Labview or other language.
I hope this can clear you out
