Hi, I used to think I was capable of handling the difficulties I face in Linux, until I tried to get my modem work in Ubuntu Gutsy. Here I present you the ScanModem output of my laptop (fujitsu-siemens, amilio pro with Intel duo processor) and give my best appreciations for any help about what I should do. I couldn't work out even the chipset of the device from the ModemData.txt :(((. Thanks, Janberk -------------------------- System information ---------------------------- CPU=i686, Linux version 2.6.22-14-generic (buildd@palmer) (gcc version 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2)) #1 SMP Sun Oct 14 23:05:12 GMT 2007 scanModem update of: 20071030 The modem symbolic link is /dev/modem -> ttySHSF0 There are no blacklisted modem drivers in /etc/modprobe* files Potentially useful modem drivers now loaded are: hsfusbcd2 hsfmc97sis hsfmc97ati hsfmc97ali hsfmc97via hsfmc97ich hsfpcibasic2 hsfserial hsfengine hsfosspec hsfsoar The Advanced Linux Sound Architecture (ALSA) packages providing audio support on your System, also includes drivers for some modems. Diagnostics are under the /proc/asound/ folders. For modems using the snd-hda-intel audio+modem driver, upgrades to a new ALSA version are sometimes necessary to achieve function. See for example: http://linmodems.technion.ac.il/bigarch/archive-seventh/msg02144.html. Audio cards with the ALC883 chipset may require an upgrade to ALSA version 1.0.15 for modem support, see http://linmodems.technion.ac.il/bigarch/archive-seventh/msg02577.html Copying ALSA diagnostics to Modem/ALSAjanberk.tgz ALSAversion = 1.0.14 Summary card and chipset information is in: /proc/asound/cards: 0 [Intel ]: HDA-Intel - HDA Intel HDA Intel at 0xdc240000 irq 23 /proc/asound/pcm: 00-01: Conexant Digital : Conexant Digital : playback 1 00-00: CONEXANT Analog : CONEXANT Analog : playback 1 : capture 1 USB modem not detected by lsusb For candidate card, firmware information and bootup diagnostics are: PCI slot PCI ID SubsystemID Name ---------- --------- --------- -------------- 00:1b.0 8086:27d8 1734:10ad Audio device: Intel Corporation 82801G Modem interrupt assignment and sharing: 23: 609436 0 IO-APIC-fasteoi HDA Intel --- Bootup diagnostics for card in PCI slot 00:1b.0 ---- [ 16.872000] ACPI: PCI Interrupt 0000:00:1b.0[A] -> GSI 22 (level, low) -> IRQ 23 [ 16.872000] 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 8086:27d8 may host a soft modem chip.

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. 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 269256 2007-10-04 22:57 /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) sudo chmod a+x /usr/sbin/pppd or under Ubuntu related Linuxes sudo 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 eth1 Which can interfere with Browser naviagation.
