- -------------------------- System information ----------------------------
- CPU=i686, Linux Mint Cassandra
- Linux version 2.6.20-16-generic ([email protected]) (gcc version 4.1.2 (Ubuntu 4.1.2-0ubuntu4)) #2 SMP Thu Jun 7 20:19:32 UTC 2007
- scanModem update of: 2007-20-07
- There are no blacklisted modem drivers in /etc/modprobe* files
- The Advanced Linux Sound Architecture (ALSA) packages providing audio support on your System,
- also includes drivers for some modems. High Definition Audio (HDA) cards can themselves host
- a softmodem chipset, with both audio+modem supported by a snd-hda-intel driver.
- The ALSA diagnostics are written during bootup to /proc/asound/ folders.
- Summary card and chipset information is in:
- /proc/asound/cards:
- 0 [Intel ]: HDA-Intel - HDA Intel
- HDA Intel at 0xd8500000 irq 16
- 1 [CMI8738MC6 ]: CMI8738-MC6 - C-Media PCI CMI8738-MC6
- C-Media PCI CMI8738-MC6 (model 55) at 0xc800, irq 22
- /proc/asound/pcm:
- 00-02: ALC880 Analog : ALC880 Analog : capture 2
- 00-00: ALC880 Analog : ALC880 Analog : playback 1 : capture 2
- 01-02: CMI8738-MC6 : C-Media PCI IEC958 : playback 1 : capture 1
- 01-01: CMI8738-MC6 : C-Media PCI 2nd DAC : playback 1
- 01-00: CMI8738-MC6 : C-Media PCI DAC/ADC : playback 1 : capture 1
- A copy of /proc/asound had been copied to Modem/ALSAroot.tgz
- PCI slot 00:1b.0 has a High Definition Audio Card
- USB modem not detected by lsusb
- For candidate card, firmware information and bootup diagnostics are:
- PCI slot PCI ID SubsystemID Name
- ---------- --------- --------- --------------
- 06:01.0 14f1:2f00 14f1:2004 Communication controller: Conexant HSF 56k HSFi Modem
- Modem interrupt assignment and sharing:
- --- Bootup diagnostics for card in PCI slot 06:01.0 ----
- For candidate card, firmware information and bootup diagnostics are:
- PCI slot PCI ID SubsystemID Name
- ---------- --------- --------- --------------
- 00:1b.0 8086:2668 8086:e307 Audio device: Intel Corporation 82801FB/FBM/FR/FW/FRW
- Modem interrupt assignment and sharing:
- --- Bootup diagnostics for card in PCI slot 00:1b.0 ----
- [ 40.898571] ACPI: PCI Interrupt 0000:00:1b.0[A] -> GSI 16 (level, low) -> IRQ 16
- [ 40.898592] PCI: Setting latency timer of device 0000:00:1b.0 to 64
- === Finished modem firmware and bootup diagnostics section. ===
- === Next deducing cogent software ===
- The High Defintion Audio card with PCI ID 8086:2668 may host a soft modem chip.
- The NotDetermined is not supported by this kernel.
- There is candidate modem software.
- For candidate modem in PCI bus: 00:1b.0
- Class 0403: 8086:2668 Audio device: Intel Corporation 82801FB/FBM/FR/FW/FRW
- Primary PCI_id 8086:2668
- Subsystem PCI_id 8086:e307
- Softmodem codec or chipset from diagnostics:
- from Archives:
- Lacking a dsp (digital signal processing) chip, the modem is a software
- intensive or "softmodem" type. Its primary controller manages the traffic
- with the CPU. But the software needed is specified in the Subsystem.
- -----------------------------------------
- Support type needed or chipset:
- Support can likely be achieved through two mutually exclusive alternatives:
- 1) The hsfmodem software for Conexant chipset modems: Read Conexant.txt
- The following ALSA alternative CANNOT work with Conexant modems.
- 2) An ALSA modem driver plus slmodemd. Read Smartlink.txt for details, and
- to test get the package SLMODEMD.gcc4.1.tar.gz from:
- http://linmodems.technion.ac.il/packages/smartlink/
- Writing Intel.txt
- For owners of a Dell PCs with Conexant HSF modems, a driver source package with full speed enabled is available, but requires driver compiling. Read Conexant.txt
- Read Conexant.txt
- Writing Conexant.txt
- Writing Smartlink.txt
- ============ end Smartlink section =====================
- For candidate modem in PCI bus: 06:01.0
- Class 0780: 14f1:2f00 Communication controller: Conexant HSF 56k HSFi Modem
- Primary PCI_id 14f1:2f00
- Support type needed or chipset: hsfmodem
- For owners of a Dell PCs with Conexant HSF modems, a driver source package with full speed enabled is available, but requires driver compiling. Read Conexant.txt
- The hsfmodem package serves a great variety of Conexant chipset modems.
- Start at http://www.linuxant.com/drivers/hsf for
- eventually download of a hsfmodem-SomeVersion.zip package with
- SomeVersion containing your kernel_version 2.6.20-16-generic in the filename if possible.
- These packages have compiled drivers. Otherwise download the generic
- hsfmodem-Version.tar.gz package. Its usage will require compiling.
- Read Conexant.txt
- Writing Conexant.txt
- Completed candidate modem analyses.
- The base of the UDEV device file system is: /dev/.udev
- Versions adequately match for the compiler installed: 4.1.2
- and the compiler used in kernel assembly: 4.1.2
- Minimal compiling resources appear complete:
- make utility - /usr/bin/make
- Compiler version 4.1
- linuc_headers base folder /lib/modules/2.6.20-16-generic/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 libc6-dev (and for Debian/Ubuntu, linux-libc-dev). The also required headers of package libc6 are commonly installed by default.
- For Debian and some related distributions, a package kernel-kbuild-2.6-20 may be needed to support driver compiling
- 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 pacakage
- 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
- Checking pppd properties:
- -rwsr-xr-- 1 root dip 269224 2007-04-05 11:41 /usr/sbin/pppd
- In case of an "error 17" "serial loopback" problem, see:
- http://phep2.technion.ac.il/linmodems/archive-sixth/msg02637.html
- To enable dialout without Root permission do:
- $ su - root (not for Ubuntu)
- chmod a+x /usr/sbin/pppd
- or under Ubuntu related Linuxes
- chmod a+x /usr/sbin/pppd
- Checking settings of: /etc/ppp/options
- asyncmap 0
- noauth
- crtscts
- lock
- hide-password
- modem
- proxyarp
- lcp-echo-interval 30
- lcp-echo-failure 4
- noipx
- In case of a message like:
- Warning: Could not modify /etc/ppp/pap-secrets: Permission denied
- see http://linmodems.technion.ac.il/bigarch/archive-sixth/msg04656.html
- Read Modem/YourSystem.txt concerning other COMM channels: eth0 eth0:avah
- Which can interfere with Browser naviagation.
- Don't worry about the following, it is for the experts
- should trouble shooting be necessary.
