配置华为E3276调制解调器
我在Ubuntu 14.04上遇到了移动宽带调制解调器（华为E3276）的问题。
lsusb输出：
Bus 002 Device 024: ID 12d1:1506 Huawei Technologies Co., Ltd. E398 LTE/UMTS/GSM Modem/Networkcard 当我插入调制解调器时，/var/log/usb_modeswitch.log中出现以下内容：

我不明白日志是否一切正常或配置有问题。 无论如何，调制解调器不会出现在Unity的网络菜单中。
我找到了尝试wvdial的地方说明。 我编辑/etc/wvdial.conf如下：
[Dialer Defaults] Init1 = ATZ Init2 = ATQ0 V1 E1 S0=0 Modem Type = Analog Modem Baud = 9600 New PPPD = yes Modem = /dev/ttyUSB0 ISDN = 0 ; Phone = ; Password = ; Username = [Dialer tele2] Modem = /dev/ttyUSB0 Phone = *99# Username =; Password =; Init1 = ATZ Init2 = AT+CPIN=1689 Init3 = AT+CGDCONT=1,"IP","4g.tele2.ee" Auto DNS = on
vwdial输出如下：
$ wvdial tele2 --> WvDial: Internet dialer version 1.61 --> Initializing modem. --> Sending: ATZ ATZ OK --> Sending: AT+CPIN=1689 AT+CPIN=1689 OK --> Sending: AT+CGDCONT=1,"IP","4g.tele2.ee" AT+CGDCONT=1,"IP","4g.tele2.ee" OK --> Modem initialized. --> Sending: ATDT*99# --> Waiting for carrier. ATDT*99# CONNECT --> Carrier detected. Waiting for prompt. --> Connected, but carrier signal lost! Retrying... --> Sending: ATDT*99# --> Waiting for carrier. --> Timed out while dialing. Trying again. --> Sending: ATDT*99# --> Waiting for carrier. --> Timed out while dialing. Trying again. --> Sending: ATDT*99# --> Waiting for carrier.
所以似乎vwdial可以使用调制解调器，但不连接到网络。 什么可能是错的任何建议？
编辑：这是我插入设备时在syslog中报告的ModemManager和NetworkManager：

我通过创建以下文件在（K）Ubuntu 14.04.3（和14.04）上运行我的华为E3276：
# custom udev rules for UMTS modems ACTION=="add", SUBSYSTEM=="usb", ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="14fe", RUN+="/usr/sbin/usb_modeswitch -v 12d1 -p 14fe -M '55534243123456780000000000000011062000000100000000000000000000'" ACTION=="add", SUBSYSTEM=="usb", ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="1506", RUN+="/bin/bash -c 'modprobe option && echo 12d1 1506 > /sys/bus/usb-serial/drivers/option1/new_id
我把它保存为/lib/udev/rules.d/70-usb-modeswitch.rules 。
插入usb后运行以下命令：
sudo usb_modeswitch -J -v 0x12d1 -p 0x14fe
如果不起作用，请下载并安装usb_modeswitch和usb_modeswitch数据最新版本
https://launchpad.net/ubuntu/+source/usb-modeswitch/2.2.5+repack0-1ubuntu1/+build/8089712 http://packages.ubuntu.com/wily/all/usb-modeswitch-data/download
重新启动，插入设备并再次尝试上面的sudo usb_mode …命令。
