Asunto: Improving USB support
Pedro,
I have to use Wvdialconf because scanmodem does not worked for me. I am
here trying to find the "lost step(s)" ;-) so newbies can have it more easy
next time to plug and surf..
Better USB support is being worked up in recent scanModem updates.
But I need test cases to improve automation.
Please run the current scanModem on your System,
and send me the ModemData.txt

I would also add support for Novatel Ovation MC950D, ZTE MF620 and Huawei
E270 (other used USB modems, see http://en.wikipedia.org/wiki/Huawei_E220 ;
specially interesting is the Novatel).
What about to use HAL instead of lsusb? (USB modem was detected by Ubuntu,
because it mounted 2 USB devices, one of them is the virtual USB CD-ROM with
the Linux drivers in Huawei E220). The other icon, one could (but nowadays
cannot) be used to click and connect/disconnect to the Internet (this would
be very usefull and practical for a newbie).
Here there is ModemData.txt file for Huawei E220 (some more info in
https://help.ubuntu.com/community/DialupModemHowto/Huawei/E220 ):

with USB and bridge devices not displayed.
**********************
If your modem is connected by an external serial cable,
or mounted internally on an ISA card, scanModem would not access it.
Try with Root permission
$ sudo wvdialconf /etc/wvdial.conf
to detect these modem types and some USB modems.
If the detection is successful, read the wvdial.txt .
Edit the /etc/wvdial.conf with Root permission:
sudo gedit /etc/wvdial.conf
will be able to dial out with Root permission:
sudo wvdial
************************
Many modems for which scanModem fails have Conexant chips.
From http://www.linuxant.com/drivers/modemident.php
get the ListModem tool, which will report on Conexant chipset modems
If the above tests fail, please provide any independent information
available on your modem.
If an alternative boot into Microsoft windows can be done, do mouse
clicks on:
Start > Settings > Control Panel > Classical View (for Window XP) > System
Hardware > Device Manager > Modems > Click on the + > Modem. Double click
to
expand the graphic. Manufacturer information may be displayed. For example,
CXT
stands for Conexant. Click the Diagnostics Tab. Record any hardware ID or
vendor
and device information.
Next do the Query Modem and record the ATI specifications displayed such as:
ATI3 - Agere SoftModem Version 2.1.22
ATI5 - 2.1.22, AMR Intel MB, AC97 ID:SIL REV:0x27
Try to identify the modem setup file, with name perhaps MODEM.INF.
If may contain chipset Vendor informaton.
The /proc/asound/ audio+modem diagostics are being copied.

The base of the UDEV device file system is: /dev/.udev
Versions adequately match for the compiler installed: 4.1.3
and the compiler used in kernel assembly: 4.1.3
Minimal compiling resources appear complete:
make utility - /usr/bin/make
Compiler version 4.1
linuc_headers base folder /lib/modules/2.6.22-14-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.
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 package
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

In case of an "error 17" "serial loopback" problem, see:

To enable dialout without Root permission do:
$ su - root (not for Ubuntu)
sudo chmod a+x /usr/sbin/pppd
