Rather thna pretend I know something about winmodems i hopefully will direct you to the right spot
go to the the one that says december31 release - and you will have to agree about teh license thing - then pink out an appropriate driver for your system. i am guessing that even though it is detected it will not be set up yet and you will need to install the driver.
please check out the docs for installation - they are listed to the right of the page. after they are installed let us know if any issues come up
