USB Modem Does Not Dial

Support knowledgebase (jbartsh_usb_modem)
Applies to

SuSE Linux: Version 7.3

Symptom

After the successful setup of a USB modem, it is impossible to dial with the created configuration.
An error message, like the following one, is displayed: /dev/ttyACM0 invalid argument

Cause

An error in the by default installed Kernel 2.4.10

Solution

You can download an official kernel update from our FTP server to fix this problem.
Please proceed as follows:

Log in as user root.

Check which kernel version you are currently using:

uname -r

rpm -qf `awk -F= '/image/{print $2}' < /etc/lilo.conf`

An output example:

tux# uname -r

2.4.10-4GB 

tux# rpm -qf `awk -F= '/image/{print $2}' < /etc/lilo.conf`

k_deflt-2.4.10-23

Download the corresponding kernel from the following URL.

ftp://ftp.suse.com/pub/suse/i386/update/7.3/kernel/2.4.16/

Install the kernel with following commands:

rpm -Uhv k_XX.i386.rpm

mk_initrd

lilo

(Obviously XX stands for the version you are using)

Finally, restart your computer
