winmodems are notoriously hard to get working,
Because Lazy hardware vendors are too slack to support linux.
Next time you buy a computer, show your support for linux and
buy one which supports linux
Of course, that doesn't help you right now.
The only drivers for connexant winmodems I know of are the Linuxant drivers, which you can get here :
http://www.linuxant.com/drivers/?PHP...749e21787cc2c4
Unfortunately, to get full speed out of them, you need to buy the driver.
(Which sucks, but it was the only way they could get around Connexant's NDA and still have a usable driver)
