Using a USB winmodem with a Conexant driver in (K)Ubuntu 11.04 (Natty)

**Ganton** · June 13th, 2011

With the information given by Diaco, Lamp20, Shizeon, Backu and the writers of http://help.ubuntu.com/community/Dia...Howto/Conexant I have used a USB winmodem with a conexant driver in (K)Ubuntu 11.04 (Natty).

When I plugged that modem, I executed

Code:

lsusb

and it said:

[...]
Bus 006 Device 002: ID 0572:1300 Conexant Systems (Rockwell), Inc. SoftK56 Data Fax Voice CARP
[...]

so I knew that the HSF modem was recognized by the system.

As I had a previous internet connection, I upgraded the system

Code:

sudo apt-get update && sudo apt-get dist-upgrade

I checked that I had no previous Conexant drivers installed. For example: I executed "ls /usr/sbin/hsfconfig", and it said that that file did not exist; if it existed I would have thought that something was still installed.

I made sure that I had gcc prepared, executing

Code:

sudo apt-get install gcc

Then I executed those steps told there:

Code:

sudo -s
cd /lib/modules/$(uname -r)/build/include/linux
ln -s ../generated/utsrelease.h
ln -s ../generated/autoconf.h
exit

I prepared the files for the driver compilation, executing

Code:

mkdir ~/conexant_modem
cd ~/conexant_modem

and if I had a 64-bit operating system I executed

Code:

wget http://linux.dell.com/files/ubuntu/hardy/modem-drivers/hsf/hsfmodem-7.68.00.09x86_64oem.tar.gz
tar xzf hsfmodem-7.68.00.09x86_64oem.tar.gz
wget http://www.bargweb.net/images/2009/november/hsfmodem-7.80.02.05-DiacoEdition.zip
unzip hsfmodem-7.80.02.05-DiacoEdition.zip
cp -a hsfmodem-7.80.02.05-DiacoEdition/modules/imported/include/framewrk.h hsfmodem-7.68.00.09x86_64oem/modules/imported/include/framewrk.h
cp -a hsfmodem-7.80.02.05-DiacoEdition/modules/imported/include/osservices.h hsfmodem-7.68.00.09x86_64oem/modules/imported/include/osservices.h

else, if I had a 32-bit operating system I executed

Code:

wget http://linux.dell.com/files/ubuntu/hardy/modem-drivers/hsf/hsfmodem-7.68.00.09oem.tar.gz
tar xzf hsfmodem-7.68.00.09oem.tar.gz
wget http://www.bargweb.net/images/2009/november/hsfmodem-7.80.02.05-DiacoEdition.zip
unzip hsfmodem-7.80.02.05-DiacoEdition.zip
cp -a hsfmodem-7.80.02.05-DiacoEdition/modules/imported/include/framewrk.h hsfmodem-7.68.00.09oem/modules/imported/include/framewrk.h
cp -a hsfmodem-7.80.02.05-DiacoEdition/modules/imported/include/osservices.h hsfmodem-7.68.00.09oem/modules/imported/include/osservices.h

A note for the curious ones: those "framewrk.h" and "osservices.h" files were the different ones between the directories "hsfmodem-7.68.00.09oem/modules/imported" and "hsfmodem-7.80.02.05-DiacoEdition/modules/imported".

If I had a 64-bit operating system I executed

Code:

wget http://www.linuxant.com/drivers/hsf/full/archive/hsfmodem-7.80.02.06x86_64full/hsfmodem-7.80.02.06x86_64full.tar.gz

else, if I had a 32-bit operating system I executed

Code:

wget http://www.linuxant.com/drivers/hsf/full/archive/hsfmodem-7.80.02.06full/hsfmodem-7.80.02.06full.tar.gz

A note for the curious ones: that file was the newest one in http://www.linuxant.com/drivers/hsf/full/downloads.php

And then, if I had a 64-bit operating system I executed

Code:

tar xzf hsfmodem-7.80.02.06x86_64full.tar.gz
rm -r hsfmodem-7.80.02.06x86_64full/modules/imported
cp -R hsfmodem-7.68.00.09x86_64oem/modules/imported hsfmodem-7.80.02.06x86_64full/modules/
cp -R hsfmodem-7.68.00.09x86_64oem/modules/imported hsfmodem-7.80.02.06x86_64full/modules/

else, if I had a 32-bit operating system I executed

Code:

tar xzf hsfmodem-7.80.02.06full.tar.gz
rm -r hsfmodem-7.80.02.06full/modules/imported
cp -R hsfmodem-7.68.00.09oem/modules/imported hsfmodem-7.80.02.06full/modules/
cp -R hsfmodem-7.68.00.09oem/modules/imported hsfmodem-7.80.02.06full/modules/

The next step was to clean the present directory.

If I had a 64-bit operating system I executed

Code:

rm -rf hsfmodem-7.68.00.09x86_64oem
rm -rf hsfmodem-7.80.02.05-DiacoEdition
rm hsfmodem-7.68.00.09x86_64oem.tar.gz
rm hsfmodem-7.80.02.05-DiacoEdition.zip
rm hsfmodem-7.80.02.06x86_64full.tar.gz

else, if I had a 32-bit operating system I executed

Code:

rm -rf hsfmodem-7.68.00.09oem
rm -rf hsfmodem-7.80.02.05-DiacoEdition
rm hsfmodem-7.68.00.09oem.tar.gz
rm hsfmodem-7.80.02.05-DiacoEdition.zip
rm hsfmodem-7.80.02.06full.tar.gz

Then I had to change some files to adapt them to work with the 2.6.38 kernel.
If I had a 64-bit operating system I executed

Code:

cd hsfmodem-7.80.02.06x86_64full
xdg-open modules/GPL/serial_cnxt.c

else, if I had a 32-bit operating system I executed

Code:

cd hsfmodem-7.80.02.06full
xdg-open modules/GPL/serial_cnxt.c

and then a text editor was executed. I searched for the string

Code:

#ifndef FOUND_UART_REGISTER_PORT

Below I found the string

Code:

static DECLARE_MUTEX(cnxt_port_sem);

and I deleted that string, and wrote there

Code:

static DEFINE_SEMAPHORE(cnxt_port_sem);

I executed

Code:

xdg-open modules/osdiag.c

and then a text editor was executed. I searched for the string

Code:

.owner	= THIS_MODULE,

Below I found the string

Code:

.ioctl	= diag_ioctl,

and I deleted that string, and wrote there

Code:

.compat_ioctl = diag_ioctl,

I executed

Code:

xdg-open modules/osnvm.c

and then a text editor was executed. I searched for the string

Code:

static LIST_HEAD(nvm_newinst_list);

Below I found the string

Code:

static DECLARE_MUTEX(nvmelem_writelist_sem);

and I deleted that string, and wrote there

Code:

static DEFINE_SEMAPHORE(nvmelem_writelist_sem);

A note for the curious ones: the source of those changes in those files was http://www.openmamba.org/showfile.ht...l-2.6.37.patch

And finally...
If I had a 64-bit operating system I executed

Code:

cd hsfmodem-7.80.02.06x86_64full
sudo make install
sudo hsfconfig

else, if I had a 32-bit operating system I executed

Code:

cd hsfmodem-7.80.02.06full
sudo make install
sudo hsfconfig

It asked "Where is the linux source build directory that matches your running kernel?", then I simply pressed the return key to accept the default answer. I also accepted the default answer in other questions.

I executed

Code:

dmesg

and at the end I saw

Code:

    [59190.782005] hsfengine: module license 'see LICENSE file distributed with driver' taints kernel.
    [59190.782011] Disabling lock debugging due to kernel taint

    [59196.994150] usbcore: registered new interface driver hsfusbcd2

which meant, among other things, that the USB modem was detected at /dev/ttySHSF0, so I could use kppp (for example) and configure it specifying that the modem was at /dev/ttySHSF0.

Note: as they said in https://help.ubuntu.com/community/Di...Howto/Conexant: "do not delete or move the source tree [in our case: ~/conexant_modem] from your system after these steps, it will be required to uninstall and patch the driver."

Note: if you find any problem, or want to make any change to the method, please write it in this thread, so we can have a proper final document.

This thread is about "Using a USB winmodem with a Conexant driver in (K)Ubuntu 11.04 (Natty)". Using the version 3.0.0 of the Linux kernel is not what expected

Well, I had a fax to send out, and only 3.0.0 kernel machines to work with, so I slugged through making this work for the 3.0.0 Linux kernel, for use on Ubuntu 11.10. Here's what I had to do, beyond what was originally specified above:

1. In modules/osservices.c, use the new mutex.h header, define a mutex, and replace all instances of lock_kernel() and unlock_kernel():

Code:

- #include <linux/smp_lock.h>
+ #include <linux/mutex.h>
+ DEFINE_MUTEX(os_mutex);

- lock_kernel();
+ mutex_lock(&os_mutex);

- unlock_kernel();
+ mutex_unlock(&os_mutex);

2. In multiple files (in modules and modules/GPL), replace SPIN_LOCK_UNLOCKED declarations:

Code:

- static spinlock_t dcp_lock = SPIN_LOCK_UNLOCKED;
+ static DEFINE_SPINLOCK(dcp_lock);

or

Code:

- static spinlock_t atomic_lock __attribute__((unused)) = SPIN_LOCK_UNLOCKED;
+ static DEFINE_SPINLOCK(atomic_lock);

The files I found that in were:

modules/osdcp.c
modules/osdiag.c
modules/osfloat.c
modules/osservices.c
modules/GPL/oscompat.h

...and then run 'sudo hsfconfig' again, and it builds! I tested it thereafter with efax-gtk, in which I used "ttySHSF0" as the Serial Device, as was specified by hsfconfig. Your device may have a different name.

Hope this helps!

Yes! Your writings helped me to make the driver compile and execute in the new 11.10 version ("Oneiric"). I'll try the driver more times. If it works OK, I'll create a new page, particular for the 11.10 version ("Oneiric").

Thanks!
