【SOCLAB】HUAWEI无线上网卡——拨号使用手册

为了实验室以后的发展，防止知识断层，以后尽量把实验室的一些使用资料进行记录。

打开网关电源开关，登入之后，插入无线上网卡设备，打印如下信息：

usb 1-1.4: new full speed USB device using s3c2410-ohci and address 4
usb 1-1.4: New USB device found, idVendor=12d1, idProduct=1446

sr0: scsi-1 drive
Uniform CD-ROM driver Revision: 3.20
sr 0:0:0:0: Attached scsi generic sg0 type 5

这个是驱动打印出来的信息，这个涉及到驱动移植，之前康璐学长已经对驱动的移植做过记录，大家可以参考： http://blog.csdn.net/kangkermit/article/details/8134827

然后进行usb mode switch；

[root@FriendlyARM /apps]# /usb/usb_modeswitch -c /usb/usb_modeswitch.conf

Looking for target devices ...
 No devices in target mode or class found
Looking for default devices ...

这些事usb mode转换，是一个工具，大家需要移植的，后期我会对他的移植进行详细介绍，大家可以先了解下： http://www.draisberghof.de/usb_modeswitch/

然后还会后续打印一些信息：

scsi 4:0:0:0: CD-ROM            HUAWEI   Mass Storage     2.31 PQ: 0 ANSI: 0
sr0: scsi-1 drive
sr 4:0:0:0: Attached scsi generic sg0 type 5

这个大家不用管他。

这时候设备目录下面出现了我们需要的设备：

[root@FriendlyARM /apps]# ls /dev/ttyUSB*
/dev/ttyUSB0  /dev/ttyUSB1  /dev/ttyUSB2  /dev/ttyUSB3

这样我们拨号的前奏就做的差不多了，下面我们来研究研究拨号的脚本：

[root@FriendlyARM /apps]# cat /usb/cdma2000 
nodetach
lock
/dev/ttyUSB3
921600
crtscts
hide-password
#caoke
user 1537700000
password 700223 

#raoling
#user 13307157221
#password 19931115

usepeerdns
noauth
noipdefault
novj
novjccomp
noccp
defaultroute
ipcp-accept-local
ipcp-accept-remote
connect '/usr/sbin/chat -s -v -f /usb/chat-cdma2000-connect'
disconnect '/usr/sbin/chat -s -v -f /usb/chat-cdma2000-disconnect'

为了确保大家以后正常使用，大家以后对我这个脚本就不要随便改了，只需要改的是user和password，这次我用的是曹可的手机卡，这里为了他的隐私我把他的手机卡号给改了，密码也是随便写的；

这个改完后，就可以拨号了。

拨号成功了，我们用ifconfig命令看看：

[root@FriendlyARM /apps]# ifconfig

多了个网卡ppp0，这个就是我们的无线上网卡，我们来测试下：

[root@FriendlyARM /apps]# ping -I ppp0 4.2.2.2

4.2.2.2是全球公用的DNS，到这里无线上网卡的使用已经介绍完了，希望大家好好做！
