问题：移动3G[ZTE A356] TD-SCDMA/HSDPA
描述:
做法：
[root@TQ210]#lsusb
Bus 001 Device 001: ID 1d6b:0001
Bus 001 Device 002: ID 1a40:0101
Bus 001 Device 003: ID 19d2:0120
1. 使用usb_modeswitch切换工作模式
[root@TQ210]#usb_modeswitch -c /etc/A356.cfg
[root@TQ210]#lsusb
Bus 001 Device 001: ID 1d6b:0001
Bus 001 Device 002: ID 1a40:0101
Bus 001 Device 004: ID 19d2:0079
==============> /etc/A356.cfg
DefaultVendor= 0x19d2
DefaultProduct= 0x0120
TargetVendor= 0x19d2
TargetProduct= 0x0079
DetachStorage /> MessageC /> Interface=0x00
NeedResp />
2. 4.安装驱动程序
insmod usbserial.ko
insmod usb_wwan.ko
insmod option.ko
[root@TQ210]#ls -l /dev/ttyUSB
ttyUSB0 ttyUSB1 ttyUSB2 ttyUSB3
3.用pppd拨号
pppd call td-dailer
具体配置文件：
=========================>td-dailer
