首先，这是一个比较简单的问题
我是在Linux下和windows下作了一个对比
1，windows下第一次插入该猫的时候，会以一个usb外接存储设备显示出来，并且看上去是一个CD-ROM的Media设备，当在windows下安装完电信的拨号程序以后，这个CDROM的设备就不见了，然后打开windows的超级终端，会看到三个新的串口设备
2，在Linux下，无论什么时候插入该猫的时候，都会是一个usb外接存储设备显示出来，并且看上去是一个CD-ROM的Media设备
然后通过cat /proc/kmsg获得相关调试信息，我使用的kernel是加了kernel hacking选项的，也就是说，打印信息会多点，方便调试，看到如下信息：

然后ls /dev就可以看到一些关键设备，比如sr0

然后lsusb可以看到我们的新usb的相关信息

可以看出来，关键的是：Bus 006 Device 004: ID 05c6:2001 Qualcomm, Inc.
可以看到，其Vendor: 05c6 ProductID:2001
其实这个就是我们刚才看到的/dev/sr0相对应的usb的信息
可以说，之前说过的都等于白说，仅仅是一些信息的获得，经过观察可以看出来，在windows下安装完拨号程序以后，就看不到cdrom了，这个时候就可以看到串口设备了，那么可以总结，应该是有一个将cdrom给弹出来了，这个时候使用了一下如下命令
eject /dev/sr0
这样就把Media弹出了，然后再lsusb看一下

这回好了，看到结果了，Bus 006 Device 005: ID 1e0e:ce16
结果就是，这个usb的VendorID: 1e0e ProductID:ce16
然后看一下/dev/下的设备

多了三个串口设备，这样就对了，接下来就可以使用串口设备了
使用minicom先试试哪个串口好用

通过AT指令可以看出来，可以玩了，接下来设置一下conf就可以了，这个在网上应该可以找到各种方法来连接，其实都是at指令来配一下而已
