The best place to get drivers and information on them is from the vendor. See if they offer a set of LabVIEW VIs that you could use instead of the shipping DAQ functions that only work with NI boards. If they don't have any VIs, then ask what kind of programming interface they offer. If it's a DLL, then you'll need documentation on the function names and parameters. You can then use the Call Library Function. If they offer an ActiveX interface, then you'll need documentation on the available methods and properties. LabVIEW has ACtiveX functions on the Communications>ActiveX palette.
