Trying to somehow make low-level USB bus commands is the wrong mindset here.
You'll want to get whatever LabVIEW driver the vendor offers. Taking a look at the
software page on their Web site, it appears that there are LabVIEW driver libraries for a nominal charge (near bottom of the page).
For a completely "free" solution, it looks as if you can get a DLL set upon request. However, the time you spend wrapping those functions in LabVIEW would likely far outweigh the relatively small cost of their LabVIEW driver. Of course, if they do actually charge you something like $80 for the LabVIEW driver, then you are beginning to see why it might have been more cost-effective for you to just go with NI hardware in the first place, and the concomitant excellent and free LabVIEW integration, the numerous programming examples, the excellent user community, etc.
