BSNL's WLL(Clarity IIA) does not work with Ubuntu jaunty(9.04)

I done the following(and many others also):

1. Just download this executable…..bsnlclarity and save it to your home folder.

2. Connect your phone to the system with the usb cable.

3. Now at terminal type

$ sudo ./bsnlclarity

You will be asked for your username and password for accessing the internet enter it …..
now start surffing

Ctrl+C to stop

Here is the step by step method

1) Step 1 Load the driver

$ sudo /sbin/modprobe usbserial vendor=0×15eb product=0×0001

2) load ppp driver

$ sudo /sbin/modprobe ppp_generic

3) Check dmesg output

$ sudo dmesg

I got
[ 227.271459] /build/buildd/linux-2.6.24/drivers/usb/serial/usb-serial.c: USB Serial support registered for generic
[ 227.271485] usbserial_generic 2-1:1.0: generic converter detected
[ 227.271616] usb 2-1: generic converter now attached to ttyUSB0
[ 227.271627] usbserial_generic 2-1:1.1: generic converter detected
[ 227.271687] usb 2-1: generic converter now attached to ttyUSB1

[ 276.412779] PPP generic driver version 2.4.2

4) run wvdialconf

$ sudo wvdial.conf

This create a skeleton wvdial.conf

5) Edit it so that it looks like

$ sudo gedit /etc/widial.conf

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init3 = at+crm=1;+cmux=1;+cps=33;+cta=0
Modem Type = Analog Modem
ISDN = 0
Phone = #777
Modem = /dev/ttyUSB0
Username = YOUR_USERNAME
Password = YOUR_PASSWORD
Baud = 460800
Stupid Mode = 1
Auto DNS
Check Def Route

Enter your username and password…username is your phone number including your std code but no zero at first….password is the last four digits of your phone number..

eg: My phone number is 0470-2150026 , so my username and password is :
Username : 4702150026
Password : 0026

6) run wvdial to connect

$ wvdial

I got
