Hi Bjorn,
I tried your modules but they wouldn't work:
FATAL: Error inserting snd_hda_intel (/lib/modules/2.6.25-gentoo-r6/kernel/sound/pci/hda/snd-hda-intel.ko): Invalid module format FATAL: Error inserting agrmodem (/lib/modules/2.6.25-gentoo-r6/extras/agrmodem.ko): Invalid module format Sep 23 07:23:10 [kernel] snd_hda_intel: disagrees about version of symbol struct_module... Sep 23 07:25:05 [kernel] agrmodem: disagrees about version of symbol struct_module
MODVERSIONS was enabled in the kernel.

With the previous attempts I've always removed the agr* modules from the extras directory that I had created after unloading them. I verified this by checking the output of lsmod and then copied over the new files and ran depmod -ae. Afterwards I would load them and check the version with modinfo. The 2.6.25er installation was from scratch. I had entirely removed it's module directory from /lib/modules before installing the modules and the kernel again so there couldn't have been any stray files lying around. The 2.6.24er download is almost complete. I'll see how it works in combination with the driver and report back any success or failure in a few minutes :).

kind regards

Hi Mehdi,
I am currently running the drivers on 2.6.25.11 with no problems. I will
forward you the precompiled modules that I have built. In theory they
will work on your system.
I deal with newer kernel versions as my distro (SuSE) provides them, so
it is not bleeding-edge, but also not too out-of date.

I should also point out that those kernel errors are oft triggered by an
odd combination of snd_hda_intel and agrmodem/agrserial.ko modules, or
any stray copies of these modules in /lib/modules.

Compiling from source is not an easy task, so please try the attached
precompiled modules first. ( be sure to remove duplicates from your
/lib/modules, issue 'depmod -ae' and then reboot to ensure all traces of
the old modules are gone).

Mehdi,

Bjorn is best qualified to comment.

What info do you have about the USB modem, when you run diagnostics
under Microsoft, as instructed in SoftModem.txt

I've used both the Alsa 1.15 and the 1.16 kernel modules. I am using the
In-Kernel drivers shipped with the kernel (on gentoo you can also use the
alsa-driver package with slightly more up to date drivers) and the version
reported is 1.16. I've nonetheless tried the 1.15er drivers to make sure
they also don't work. Using the 2.6.25er Kernel I get a little farther.
Since the 2.6.25er Kernel - I am talking about the gentoo patched kernels
that contains a number of patches and not about the vanilla kernel here -
ships alsa-1.16pre it gives me the "No stream" error mentioned on the Howto.
Thus I've used the 1.15er driver and I can at least query the modem using
Kppp. Trying to connect with the internet using wvdial or Kppp however
results in a full scale Kernel-Panik :-(. I want to make sure these issues
are related to the 2.6.25er and 2.6.26er kernel before going through the
hassle of downloading the 2.6.24er kernel sources in the hope of having more
success with it. Can anyone tell me about the state of the drivers regarding
the newer versions of the linux kernel I mentioned above?

Completed candidate modem analyses.

The base of the UDEV device file system is: /dev/.udev

Versions adequately match for the compiler installed: 4.3.1
           and the compiler used in kernel assembly: 4.3.1



Minimal compiling resources appear complete:
 make utility - /usr/bin/make
 Compiler version 4.3
 linuc_headers base folder /lib/modules/2.6.26-gentoo-r1/build

However some compilations and executable functions may need additional
files,
in the FileNames.h (so called kernel "h"eaders) collection installed in
 /usr/include/ .
For martian_modem, additional required packages are needed. The also
required headers of package libc6 are commonly installed by default.
Compiling hsfmodem drivers does require linux-libc-dev and libc6-dev
packages, for kernels 2.6.24 and later versions.
In not included on your install CD, search for them at
http://packages.ubuntu.com
or comparable Repository for other Linux distros.
When compiling ALSA drivers, the utility "patch" will also be needed.




If a driver compilation fails, with message including some lack of some
FileName.h (stdio.h for example), then
Some additional kernel-header files need installation to /usr/include. The
minimal additional packages are libc6-dev
and any of its dependents, under Ubuntu linux-libc-dev

If an alternate ethernet connection is available,
$  apt-get update
$  apt-get -s install linux-kernel-devel
will install needed packages.
For Debian/Ubuntu related distributions, run the following command to
display the needed package list:

Otherwise packages have to be found through http://packages.ubuntu.com
Once downloaded and transferred into a Linux partition,
they can be installed alltogether with:
$ sudo dpkg -i *.deb
