Modems supported by the Conexant drivers

Note: Conexant does not provide drivers for Linux, but commercial Linux drivers are available from Linuxant, a separate company. Licenses cost 19.99 US dollars. (But note that full-featured versions of the drivers are also freely available from Dell.) That comes with at least one year support and kernel-version upgrades, after which you need to purchase it again if you are running a different kernel which needs a newer version of the driver (although if you have the kernel headers installed it may be able to rebuild itself for your kernel, depending on what changes have been made in the driver - just try installing the deb and see). Without the license, the drivers are limited to a maximum speed of 14.4Kbps (this restriction does not apply to the drivers supplied by Dell). However, some Conexant modems can be run with the sl-modem-drivers (smart link) or an open source driver. Note that in general, you can buy a Lucent or Intel (smartlink, or other brand with intel chipset) modem for less than 19.99 US.

Conexant drivers provided by Dell (full-speed and free)

  • Dell provides drivers for the Conexant modems of their Linux-based laptops which should work with almost all Conexant HSF modems [1]. These drivers can be downloaded from the following addresses:

    For Ubuntu 11.10 (Oneiric Ocelot): You can follow the steps on this thread.

    For Ubuntu 11.04 (Natty Narwhal): You can follow the steps on this thread.

    For Ubuntu 10.10 (Maverick Meerkat): You can follow the steps on this thread.

    For Ubuntu 9.04, 9.10 and 10.04: Use this file. Unpack it and enter the resulting directory, do sudo make install and sudo /usr/sbin/hsfconfig

    • Note: The above didn't work for me when tested on listed-as-supported Conexant HDA modem. See section below for instructions of installing updated alsa-drivers-linuxant + latest hsfmodem + Dell's free & full-speed binaries on Ubuntu/Jaunty 9.04 which works with HDA based Conexant Modems Big Grin :)

      The above driver worked for me and didn't break my sound, if after sudo hsfconfig say NO to the option, "Would you like to use the replacement HDA modules? [yes]" - Hosed Nov162009

    For Ubuntu 8.10 (Intrepid Ibex): This hybrid approach has been reported to work (you can use this more recent package from Dell instead of the one mentioned in the forum post). For the lazy, just download this ready-made package; after unpacking it and entering the resulting directory, do sudo make install and sudo /usr/sbin/hsfconfig

    For Ubuntu 8.04 (Hardy Heron): http://linux.dell.com/files/ubuntu/hardy/modem-drivers/hsf/.

    For Ubuntu 7.10 (Gusty Gibbon): http://linux.dell.com/files/ubuntu/gutsy/modem-drivers/hsf/.

    • Download the .deb file there, double click it and it will be installed automatically.

    Ubuntu 7.04 (Feisty) users can use this link to install their Conexant HSF driver.

Building latest hsfmodem driver + free & full-speed Dell binaries

Preparation

Note: For modems hosted on High Definition Audio (HDA) cards, there is dependence upon the snd-hda-intel ALSA driver already on your System. If you upgrade ALSA beyond the version supported in the Linuxant-based driver code (including the oem distributed by Dell), the hsfmodem drivers will fail and your sound will most likely break.

Note: Ubuntu Jaunty (9.04), Hardy (8.04) and SUSE (11.0, 11.1) users with HDA modems: Installing the latest alsa-driver-linuxant package is necessary before installing this driver.

  • Installing a pre-compiled alsa-driver-linux package:

    If your distribution/architecture is not listed, or you are using a special enterprise/secure/SMP or custom (self-compiled) kernel, or the package does not work with your kernel version, try generic source package:
  • Installing Generic alsa-driver-linux package with source:

    • Note: Before installing this package, make sure that you have the build-essential installed (for gcc and make are required). Additionally, the kernel headers are also needed, this is the linux-headers package.

    •   wget http://www.linuxant.com/alsa-driver/archive/alsa-driver-linuxant-1.0.20.3/alsa-driver-linuxant_1.0.20.3_all.deb.zip
        unzip *.zip
        dpkg -i alsa-driver-linuxant_1.0.20.3_all.deb

Step 1

  • Download latest generic TAR package from Linuxant

     wget http://www.linuxant.com/drivers/hsf/full/archive/hsfmodem-7.80.02.04full/hsfmodem-7.80.02.04full.tar.gz

Step 2

  • Download oem TAR package from Dell in same directory

     wget http://linux.dell.com/files/ubuntu/hardy/modem-drivers/hsf/hsfmodem-7.68.00.09oem.tar.gz

Step 3

  • Extract both tarballs
     for i in *.tar.gz; do tar -xzf "$i"; done

Step 4

  • Replace the modules/imported/ sub-directory of the Linuxant (latest) driver with that of Dell

     rm -r hsfmodem-7.80.02.04full/modules/imported
     cp -R hsfmodem-7.68.00.09oem/modules/imported hsfmodem-7.80.02.04full/modules/

Step 5

  • Change working directory to the Linuxant (latest) driver folder and install
     cd hsfmodem-7.80.02.04full
     sudo make install
     sudo hsfconfig

For Ubuntu 9.10 Karmic users

Note: Using this driver may cause sound problems for (karmic) users. Read this post to fix it: http://ubuntuforums.org/showpost.php?p=8258559&postcount=21

After "Preparation" section download this zip archive, extract it & directly go to step 5.

  •  wget http://www.bargweb.net/images/2009/november/hsfmodem-7.80.02.05-DiacoEdition.zip

Troubleshooting - string.h error

  • If using Jaunty 9.04 (or recent kernel on Hardy 8.04), you will get an error like the following (unless you first take the steps described below to circumvent this issue): /usr/lib/hsfmodem/modules/imported/include/osservices.h:356:20: error: string.h: No such file or directory To fix it, you have two options:

  • Option 1:
     sudo gedit /usr/lib/hsfmodem/modules/imported/include/osservices.h

    Then, on line 356: change string.h to linux/string.h Then re-run sudo hsfconfig

  • Option 2:
     cd hsfmodem-7.80.02.04full
     gedit modules/imported/include/osservices.h

    Then, on line 356, change string.h to linux/string.h Then reinstall and recompile driver sudo make install && sudo hsfconfig
