according to the information you have provided, this modem is connected 
to the HD Audio bus which is not supported by the current version 
( of the HSF modem driver.

We will release very soon a new version of the HSF modem driver that 
will support the HD Audio bus.

Our modem drivers are based on source code provided by Conexant.
