檢查一下 usb_modeswitch:

/lib/udev/rules.d/40-usb_modeswitch.rules:

# Huawei E3131
ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="1f01", RUN+="usb_modeswitch '%b/%k'"

如果沒有，就加上去。

然後是 /etc/usb_modeswitch.d/
有沒有 12d1:1f01 這個 file.

雖然有 google 到一些不同得，最後是..

#Huawei E3131
DefaultVendor= 0x12d1
DefaultProduct= 0x1f01
TargetVendor= 0x12d1
RargetProduct= 0x1f01
MessageEndPoint = "0x01"

NoDriverLoading=1

這樣，插入 3G dongle,, dmesg:

pid 變成 1001, 並且出現了 ttyUSB0.1.2

有關 usb_modeswitch, 可以修改 /etc/usb_modeswitch.conf. 把 log 打開：

# Enable logging (results in a extensive report file in /var/log, named
# "usb_modeswitch_"

EnableLogging=1

這隻 dongle 好像有好多種 configuration.
ref: http://mybroadband.co.za/vb/showthread.php/507680-Huawei-HiLink-modems-%28E303-E3131-etc-%29/page2

在 modeswitch 後，minicom 開啟 ttyUSB0. 下：

AT^U2DIAG=0
AT+CFUN=4
AT+CFUN=6

之後 dongle reboot, 然後變成 網路裝置，pid 也變了...

--- 這是安裝過 CDROM mode driver 才會出現。

一但變成這個模式後，dongle 會紀錄這個模式。
以後每次插入都是這個 vid, pid, 插入 linux 也一樣。

要切回原來的模式，要 follow 上面的 link ，重新對 comport 下：

AT^U2DIAG=119
AT+CFUN=4
AT+CFUN=6

但是在 windows 下沒有出現 COM Port，插入 linux 也一樣。
認不得這個 vid, pid

就是：

# echo "12d1 1c05" >/sys/bus/usb-serial/drivers/option1/new_id 

很奇怪，一定要是 root 才行。
用 sudo 的話，會是 permission deny

然後 kernel msg:

[ 6846.542169] option 2-1.3.4:1.0: GSM modem (1-port) converter detected
[ 6846.542302] usb 2-1.3.4: GSM modem (1-port) converter now attached to ttyUSB0

[ 6846.542538] usb 2-1.3.4: GSM modem (1-port) converter now attached to ttyUSB2

這樣就出現 COM port 了。
之後用 minicom 打開 ttyUSB0.
輸入：

AT^U2DIAG=119
AT+CFUN=4
AT+CFUN=6

dongle 會重開，然後 dmesg 出來是..

回到以前的 1f01, 然後 modeswitch 到 1001

撥號連線...用 wvdial 撥號，接 ppp..
寫 /etc/wvdial.conf

[Dialer e3131]
Modem = /dev/ttyUSB0
Init1 = ATZ
Init2 = AT^CURC=0
Init3 = AT+CGDCONT=1,"IP","internet"
Phone = *99#
Stupid mode = yes
Dial Attempts = 0
Auto Reconect = yes
Password=''
Username=''

然後下命令：sudo wvdial e3131..

之後用 ifconfig 看，OK

wvdial.conf 如果沒有寫

Password=''
Username=''

wvdial 會 complain 沒有給 username, password
