linux huawei 3g modem ppp vodafone setup

when I bought this modem and the subscription from vodafone like a year ago the above mentioned dudes had no idea how to make it run under linux. they said they do tho. they had an entire dev team developing python guis that weren't working. thats tipical for corporates.



to all who cursed vodafone and friends for not being able to run their ppp, i apologize for writing this quick howto so late.


my huawei is

Bus 002 Device 005: ID 12d1:1465 Huawei Technologies Co., Ltd.

but usb_modeswitch supports many other types of devices. check your dev ids in lsusb output.

prerequisites:
- linux 2.6 system
- comgt (http://sourceforge.net/projects/comgt/)
- usb_modeswitch (http://www.draisberghof.de/usb_modeswitch/#download )

1. install comgt
2. install usb_modeswitch
3. install this as file /etc/udev/rules.d/55-huawei.rules:

ACTION=="add", SUBSYSTEMS=="scsi", DRIVERS=="sr", \
   ATTRS{vendor}=="HUAWEI  ", \
   RUN:=""
ACTION=="add", SUBSYSTEM=="usb", \
   ATTR{idVendor}=="12d1", ATTR{idProduct}=="1520", \
   RUN:="/usr/local/bin/usbflip %s{idVendor} %s{idProduct}"

install this as script /usr/local/bin/usbflip and chmod-it +x

#!/bin/sh
VID="$1"
PID="$2"
PATH=/usr/local/bin/:usr/bin:/bin:/usr/sbin:/sbin
# Need to wait for the device to settle before sending the command
sleep 1
# Huawei recommended switch sequence
echo "FLIP-FLOP: ${VID}:${PID} !!"
/usr/sbin/usb_modeswitch -v ${VID} -p ${PID} -M 55534243EE0000006000000000000611062000000000000000000000000000
sleep 1
modprobe -a option
sleep 1
echo 0x12d1 0x1465 > /sys/bus/usb-serial/drivers/option1/new_id

-insert the modem. you should see /dev/ttyUSB[0-4] being created in dev

-run:

COMGTPIN=1234 comgt -d /dev/ttyUSB0 PIN

you should get a "SIM ready" message

-run:

comgt -d /dev/ttyUSB0 reg

you should get a message like this:

root@pinkpony:~# COMGTPIN=1234 comgt -d /dev/ttyUSB0 reg
Waiting for Registration.........
Registered on Home network: "22601",2

you are kinda ready to run ppp:

pppd /dev/ttyUSB0 call vodafone

you should be getting output similar to this:
