最近入手了中国移动的G3无线宽带，G3引领3G生活嘛，自然也有咱Linuxer的份。
确定关键字之后便去Google了一番，马上便有了结果，嘿嘿。
需要安装usb_modeswitch(附加libusb) wvdial。这些软件一般都是系统自带的,手动安装在此不赘述,如: zypper in wvdial 即可，Google上查去。
请先检查您的系统里面是否已经安装有所需软件。
#zypper install wvdial
在安装好usb_modeswitch 之后编辑usb_modeswitch.conf，
其中DefaultVendor 和DefaultProduct等值是根据您的3G设备而具体设定的
比如我的设备如下：
openSuSE:/etc/udev/rules.d # lsusb | grep Huawei
Bus 005 Device 005: ID 12d1:1da1 Huawei Technologies Co., Ltd.
那么我就将/etc/usb_modeswitch.conf配置文件修改成如下：
openSuSE:~ #cat /etc/usb_modeswitch.conf
#----------------------------------
# HUawei ET128 TD-SCDMA/GSM
# Editor: l1nuxer
# Date: 2009-07-10
DefaultVendor=0x12d1
DefaultProduct=0x1da1
TargetVendor=0x12d1
TargetProduct=0x1da1
HuaweiMode=1
然后添加udev rule，这样就不需要每次插入3G设备的时候手动运行usb_modeswitch了。
openSuSE:~ #cd /etc/udev/rules.d/
openSuSE:/etc/udev/rules.d # ls
40-alsa.rules 42-bluetooth-serial.rules 52-irda.rules 65-wacom.rules 77-network.rules
40-bluetooth.rules 42-gsm-drivers.rules 52-usx2yaudio.rules 70-kpartx.rules 79-yast2-drivers.rules
40-lomoco.rules 51-gpsd.rules 55-libsane.rules 70-persistent-cd.rules 81-mount.rules
41-bluetooth-hid2hci.rules 51-hso-udev.rules 56-sane-backends-autoconfig.rules 70-persistent-net.rules 81-mptctl.rules
41-soundfont.rules 51-lirc.rules 60-pcmcia.rules 71-multipath.rules 99-iwlwifi-led.rules
在此我直接编辑42-gsm-drivers.rules 文件，您也可以自己添加任意的以.rules作为扩展名的文件，比如42-my3gmodem-drivers.rules，按照约定一般都不使用50开头的文件。
openSuSE:/etc/udev/rules.d # cat 42-gsm-drivers.rules
......
#SYSFS{idVendor}=="<YourDefaultVendorID>", SYSFS{idProduct}=="<YourDefaultProductID>", RUN+="/usr/sbin/usb_modeswitch"
SYSFS{idVendor}=="12d1", SYSFS{idProduct}=="1da1", RUN+="/usr/sbin/usb_modeswitch -c /etc/usb_modeswitch.conf"
......
可以看到输出有变化，证明我们转换成功了。
openSuSE:/etc/udev/rules.d # lsusb | grep Huawei
Bus 005 Device 005: ID 12d1:1d09 Huawei Technologies Co., Ltd.
然后运行wvdialconf 来配置modem和初始化wvdial.conf
openSuSE:/etc/udev/rules.d # wvdialconf
Editing `/etc/wvdial.conf'.
Scanning your serial ports for a modem.
Modem Port Scan<*1>: S0 S1 S2 S3 S4 S5 S6 S7
WvModem<*1>: Cannot get information for serial port.
ttyACM0<*1>: ATQ0 V1 E1 -- OK
ttyACM0<*1>: ATQ0 V1 E1 Z -- +CME ERROR: 10
ttyACM0<*1>: ATQ0 V1 E1 S0=0 -- OK
ttyACM0<*1>: ATQ0 V1 E1 S0=0 &C1 -- OK
......
Found an USB modem on /dev/ttyACM0.
Modem configuration written to /etc/wvdial.conf.
ttyACM0<Info>: Speed 460800; init "ATQ0 V1 E1 S0=0 &C1 &D2"
ttyACM1<Info>: Speed 460800; init "ATQ0 V1 E1 S0=0 &C1 &D2"
ttyACM2<Info>: Speed 460800; init "ATQ0 V1 E1 S0=0 &C1 &D2"
最后配置 wvdial 拨号
修改 /etc/wvdial.conf
注意,拨号号码是 *99***1# 为 3G的, GPRS/EDGE 的直接用 *99# 即可.
注意,以上过程是详细的配置过程,方便您手动配置,
如果您很懒,可以直接将一下内容保存为脚本 g3.sh ,并以管理员身份运行即可.
