无法使用zte（依赖cdma）AC2739 USB调制解调器连接到Ubuntu 14.0.4笔记本电脑上的互联网
许多Linux / Ubuntu用户面临这个问题 – >（使用调制解调器zte / etc连接到互联网…..）因为现代加密狗有USB存储+调制解调器+ CD ROM，usb_modes切换blablabla ……… …………..
我的问题是什么？ – >我无法**（有时能够）**使用中兴（Reliance cdma）AC2739连接互联网。
Ubuntu如何检测我的USB加密狗？ 答案：3种方式：
1）不检测USB设备，但lsusb显示设备。
2）检测设备（插入USB后10个案例中有1个）但网络管理器未将其检测为宽带连接。
3）检测设备（插入USB后15例中的1）并且网络管理器将其检测为宽带连接—–>这是我能够连接到互联网的情况。
所有3种情况的系统日志：

如果有人想要整个日志的文本文件，请告诉我。 许多USB加密狗存在此问题。 如果任何人可以提供任何解决方案，请执行此操作。 我想从3天开始希望我现在能得到解决方案。
我的中兴USB调制解调器有一个非常类似的问题，事实certificate它是作为CD单元安装的。
这就是我解决它的方法：
步骤1：使用lsusbvalidation是否检测到USB调制解调器
sergiotca@sergiotca-Dell-System-XPS-L502X:~$ lsusb Bus 002 Device 003: ID 8086:0189 Intel Corp. Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 003 Device 003: ID 046d:c07e Logitech, Inc. Bus 003 Device 009: ID 19d2:2000 ZTE WCDMA Technologies MSM Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 003: ID 0408:2fb1 Quanta Computer, Inc. Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
第2步：使用dmesg | 尾巴知道它是如何被发现的
sergiotca@sergiotca-Dell-System-XPS-L502X:~$ dmesg | tail [ 6136.744009] usb 3-1: Manufacturer: ZTE,Incorporated [ 6136.744012] usb 3-1: SerialNumber: MF1800ZTED010000 [ 6136.747257] usb-storage 3-1:1.0: USB Mass Storage device detected [ 6136.747504] scsi19 : usb-storage 3-1:1.0 [ 6137.748200] scsi 19:0:0:0: CD-ROM ZTE USB SCSI CD-ROM 2.31 PQ: 0 ANSI: 2 [ 6137.751676] sr1: scsi-1 drive [ 6137.752168] sr 19:0:0:0: Attached scsi CD-ROM sr1 [ 6137.752731] sr 19:0:0:0: Attached scsi generic sg2 type 5
步骤3：使用usb_modeswitch通过使用-K参数“弹出”来更改USB调制解调器的模式。 使用您自己的调制解调器中的供应商和产品ID（ lsusb ）
sergiotca@sergiotca-Dell-System-XPS-L502X:~$ sudo usb_modeswitch -v 0x19d2 -p 0x2000 -K [sudo] password for sergiotca: Look for default devices ... product ID matched Found devices in default mode (1) Access device 010 on bus 003 Current configuration number is 1 Use interface number 0 Use endpoints 0x01 (out) and 0x81 (in) USB description data (for identification) ------------------------- Manufacturer: ZTE,Incorporated Product: ZTE WCDMA Technologies MSM Serial No.: MF1800ZTED010000 ------------------------- Sending standard EJECT sequence Looking for active driver ... No active driver found. Detached before or never attached Set up interface 0 Use endpoint 0x01 for message sending ... Trying to send message 1 to endpoint 0x01 ... OK, message successfully sent Read the response to message 1 (CSW) ... Response successfully read (13 bytes). Trying to send message 2 to endpoint 0x01 ... OK, message successfully sent Read the response to message 2 (CSW) ... Response successfully read (13 bytes). Reset response endpoint 0x81 Reset message endpoint 0x01 -> Run lsusb to note any changes. Bye!
第4步：最后使用dmesg | tail以validation您的USB调制解调器已更改为Direct-Access模式
sergiotca@sergiotca-Dell-System-XPS-L502X:~$ dmesg | tail [ 6874.527436] usb 3-1: GSM modem (1-port) converter now attached to ttyUSB0 [ 6874.527700] option 3-1:1.1: GSM modem (1-port) converter detected [ 6874.527894] usb 3-1: GSM modem (1-port) converter now attached to ttyUSB1 [ 6874.528148] option 3-1:1.2: GSM modem (1-port) converter detected [ 6874.528305] usb 3-1: GSM modem (1-port) converter now attached to ttyUSB2 [ 6874.528510] usb-storage 3-1:1.3: USB Mass Storage device detected [ 6874.528704] scsi20 : usb-storage 3-1:1.3 [ 6875.529082] scsi 20:0:0:0: Direct-Access ZTE MMC Storage 2.31 PQ: 0 ANSI: 2 [ 6875.532997] sd 20:0:0:0: Attached scsi generic sg2 type 0 [ 6875.535452] sd 20:0:0:0: [sdb] Attached SCSI removable disk
步骤5：网络管理员现在应该检测到您的调制解调器。
仔细分析系统日志后 ，这个解决方案对我有用
问题的原因 ：现代加密狗的多种模式。
解：
1。
gedit /etc/usb_modeswitch.conf
2.将此代码添加到顶部的usb切换。
DisableSwitching = 1
3.save it。
4.再次插入usb
5.通过右键单击弹出usb cdrom
或使用。
sudo eject / dev / sr1
6.等待5-10秒（将其检测为调制解调器的时间）7。现在去网络管理员
8.Reliance网络将列在网络管理器中，通过创建新连接来连接它。
7.现在去网络经理
8.Reliance网络将列在网络管理器中，通过创建新连接来连接它。
就这样
Reliance也提供UI软件
只需使用安装它
sudo ./file name
用它来运行它
sudo ztemtapp
这对我有用。
