mainegeek, sorry, i didnt read what BFOJ said quite the same way as you need. Now i understand your post a lot better.
I took what BFOJ said and i figured he wasnt understanding that he could look on the chipset and get chip info that way. So maybe i had better explain myself a bit better as well.
BFOJ, if you look on the part, somewhere, usually on the chipset, you will find names and numbers. Sorry, i dont mean to sound simplistic, but i pretty much always have success by taking this info and plugging it into google and finding drivers, manuals, and other info. Usually you find something like : ctm3605 and under it something like;
4604 embec. So i take all these numbers and letters and google them. If i dont find anything then i shorten them and look for, say, in my example, 4604 instead of 4604 embec. Or even ctm instead of ctm3605. And also you can find info written on the card or part itself, not on the chip. You can plug any of the info into google and see if it gets you anywhere. Sometimes you have to do a lot of work and its discouraging. You go thru 3 pages of junk and all of a sudden, on page 4, there it is, just what you wanted. But its easy to get discouraged too! thing is that i can remember being pretty successful with modems as there are not even all that many mfgrs, a lot of them use the same drivers.
Failing which, you could try the FCC number, as mainegeek has already mentioned.
