One thing you might try is an interface adapter, a USB to DB-9 hardware adapter. They can be purchased for as little as $ 20 with a little shopping. They come with a device driver that turns your USB port into a Com port that will show up in Max as a com port. Since your existing software uses Visa Serial vi's this is the only thing I can think of for you. I have used this method with older hardware and proprietary software for years, and it has always worked for me.
good luck.

How will that work? You convert the PC's USB port to a DB9 serial port which cannot connect to the device because it uses a USB port.
Since the devices doesn't show up as a Com port now, the .llb that was posted just won't work. The manufacturer of the device needs to provide some sort of USB based driver and some sort of manual telling how to interface with it.

If you enjoy reverse engineering this sort of thing, take a look at the community nuggets on USB use using VISA:

It looks like you are saying the PC's physical USB port is made to appear to the operating system as a Com port, then the adapter gives you a DB-9 that you can plug any old serial device into. Is that correct? That could come in very handy... I'll have to search for one of those.
