How to install and configure Reliance Mobile broadband with Samsung Corby Speed SCH-F339 – on Debian GNU/Linux (etch) or Ubuntu?

Since I am using Mobile broadbrand with Reliance(Samsung Corby Speed) I was searching for drivers to install the modem in Linux machine. After a long search I tried for an hour and came up successfully installing the driver with Ubuntu(9.10).

Follow the simple 7 steps to configure the USB EVDO modem to conneect in Ubuntu.

1. Find The Modem, Vendor and ProdID
2. Detect the modem using modprobe
3. Plug in modem and see whether it has been found by using dmesg
4. Install dialer “wvdial” if it is not already installed
5. Configure /etc/wvdial.conf to put phone number, user name and password
6. Connect to Internet

Before installing the modem login as root in Terminal (Sudo -i)

STEP I Find The Modem, Vendor and ProdID
cat /proc/bus/usb/devices
S a m p l e
cat /proc/bus/usb/devices

Bus 006 Device 002: ID 04e8:6640 Samsung Electronics Co., Ltd Usb Modem Enumerator

Note: the above command will give a list of devices connected.
Please Find your device and its Vendor and ProdID

OR directly grep it
cat /proc/bus/usb/devices | grep Vendor

will give the Lines with word “Vendor” only
These are the lines significant in my case

cat /proc/bus/usb/devices | grep Vendor



OR use command

lsusb

lsusb

Using any of the above three you can find your EVDO modem – Vendor and ProdID

The vendor should be like

vendor=04e8

product=6640

STEP II Detect the modem using modprobe

Now use modprob to detect the modem

modprobe usbserial vendor=0×04e8 product=0×6640

Note : REMEMBER to add “0X” before your Vendor/ProdID
if Vendor=04e8 on modrpobe vendor=0×04e8
if ProdID=6640 on modrpobe product=0×6640

After Command ‘modprobe’ Plug the EVDO Modem to your USB port

STEP III Plug in modem and see whether it has been found by using dmesg

check the debug message using command ‘dmesg’

dmesg | tail

from the above dmesg command, you can find the modem device attached to which port.
In my case it was ttyACM0.

STEP IV Install dialer “wvdial” if it is not already installed
use command “wvdial” for connecting to internet
if ‘wvdial’ not install, install using command

apt-get install wvdial

(You can download wvdial from http://open.nit.ca/download/wvdial-1.54.0.tar.gz

or ftp://ftp.us.debian.org/debian/pool/main/w/wvdial/wvdial_1.54.0.orig.tar.gz)(check for the latest version)
STEP V Configure /etc/wvdial.conf to put phone number, user name and passowrd
then use command ‘wvdialconf’ for configuring wvdial

edit the file /etc/wvdial.conf to add phonenumber, username and passwd using command ‘gedit /etc/wvdial.conf’

gedit /etc/wvdial.conf

eg:
[Dialer Defaults]
Stupid Mode = on
Modem = /dev/ttyACM0
Baud = 9216000
Init = ATZ

Phone = #777
Username =93xxxxxxxx
Password = 93xxxxxxxx

New PPPD = yes

STEP VI Connect to Internet
Connect to Internet

use command wvdial in the terminal

wvdial

now you are connected to internet
