Eureka !!! Connecting to m1 3g vodafone modem in fedora7

Finally I managed to get my m1 3gsm modem working with my vaio fedora 7. This is the procedure I used for got it working.
My system is: Linux 2.6.21-1.3194.fc7 (fedora 7)
Wvdial version : WvDial 1.54.0

1) Create the following wvdial.conf

[Dialer Defaults]
Phone = *99#
Username = ppp@aplus.at
Password = ppp
Stupid Mode = 1
Dial Command = ATDT

[Dialer pin]

Init2 = AT+CPIN=5623

[Dialer A1]
Modem = /dev/ttyUSB0
Baud = 460800
Init3 = at+cgdcont=1,"ip","sunsurf"
ISDN = 0
Modem Type = Analog Modem

2) Then connect your vodafone mobile usb modem. (HUAWEI)
3) Wait till it is detected properly. (You can see logs from /var/log/messages)
4) Try to connect using wvdial.

wvdial --config wvdial.conf A1

For me it fails always like this

--> WvDial: Internet dialer version 1.54.0
--> Cannot get information for serial port.
--> Initializing modem.
--> Sending: ATZ
--> Sending: ATQ0
--> Re-Sending: ATZ
--> Modem not responding.

4) Don't worry about that. Apply the following commands

modprobe uhci_hcd ehci_hcd ppp
modprobe usbserial vendor=0x12d1 product=0x1003
rmmod usb-storage

5) Now remove the usb modem again and plug in back.
6) Wait till it is detected and try the following command again.

wvdial --config wvdial.conf A1

This time you should be able to shout "Eureka!!".
You should get the following message

[root@localhost linux-scripts]# wvdial --config wvdial.conf A1
--> WvDial: Internet dialer version 1.54.0
--> Cannot get information for serial port.
--> Initializing modem.
--> Sending: ATZ
ATZ
OK
--> Sending: at+cgdcont=1,"ip","sunsurf"
at+cgdcont=1,"ip","sunsurf"
OK
--> Modem initialized.
--> Sending: ATDT*99#
--> Waiting for carrier.
ATDT*99#
CONNECT
--> Carrier detected. Starting PPP immediately.
--> Starting pppd at Sun Jun 24 11:03:33 2007
--> pid of pppd: 5255
--> Using interface ppp0
--> local IP address 172.22.33.177
--> remote IP address 10.64.64.64
--> primary DNS address 10.11.12.13
--> secondary DNS address 10.11.12.14

Sorry I forgot one thing, You have to be a super user for doing this.

Hope you succeed on this. Else try plug it in back. It will work for sure.

Cheers!
