Need Help: How to design USB Driver for USBN9603

[LabViewFreak]

Hi,
I want to communicate with this USB-Interface-Chip USBN9603 -> http://www.farnell.com/datasheets/35246.pdf

When I take a look at this tutorial http://zone.ni.com/devzone/conceptd.nsf/webmain/6792BAB18242082786256DD7006B6416?opendocument I have to know things like vendor ID, product ID, manufacturer name, and model name of my device. Does anyone know how I can communicate with this USB-Device?
I think this is very difficult, isn't it?

Well, I don't see how you could get at the information necessary to talk with this device from the link you provide. Doesn't National Semiconductors have a Software Reference driver with SDK you can purchase for this device? You definitely need Software driver specific informations, such as the manufacturer and product ID, but also some more informations about the endpoints and possible stream formats.

Yes it seems rather difficult to me. Not a single weekend project for sure.

Actually, if the information is available, the development of a VISA driver can go pretty quickly. A coworker designed a USB board and got some basic communication done in less than a day I believe.
