[*] USB support---> USB Modem(CDC ACM)support USB Serial Converter support---> USB driver for GSM and CDMA modems
4.2、linux内核修改 drivers/usb/serial/option.c static struct usb_device_id option_ids[] = { … };在这个数组中添加两项
{ USB_DEVICE(0x19d2, 0x0031)}, { USB_DEVICE(0x19d2, 0x0034)}, 4.3、linux内核编译 make zImage make modules 5、3G模块的使用 5.1、加载内核模块 insmod option.ko insmod cdc-acm.ko
insmod slhc.ko insmod ppp_generic.ko insmod pppox.ko insmod pppoe.ko insmod ppp_synctty.ko insmod ppp_deflate.ko insmod crc-ccitt.ko insmod ppp_async.ko insmod sha1_generic.ko insmod ppp_mppe.ko
5.2、加载USB文件系统
mount-t usbfs usbfs /proc/bus/usb
5.3、ZTE-mf637u（中国联通）的使用 5.3.1、配置文件/etc/usb_modeswitch.setup # Configuration for the usb-modeswitch package, a mode switching tool for # USB devices providing multiple states or modes # # This file is evaluated by the wrapper script “usb_modeswitch” in /lib/udev # To enable an option, set it to “1”, “yes” or “true”(case doesn't matter)
# Everything else counts as “disable”
# Disable automatic mode switching globally(e.g.to acce the original # install storage)
DisableSwitching=0
# Enable logging(results in a extensive report file in /var/log, named # “usb_modeswitch_”
EnableLogging=0

Paword = any Username = any Stupid Mode = 1 5.4.2、ZTE-mu351（中国移动）的操作步骤 5.4.2.1、设置环境变量
export PATH=/root/cdma:$PATH export LD_LIBRARY_PATH=/root/cdma:$LD_LIBRARY_PATH 5.4.2.2、插入ZTE-mu351（中国移动）无线网卡
5.4.2.3、等待5秒钟左右、运行eject /dev/sr0。（5.3.3.3也可以使用此方法）5.4.2.4、运行wvdial--> WvDial: Internet dialer version 1.54.0--> Initializing modem.--> Sending: ATZ ATZ OK--> Sending: ATE0V1 ATE0V1 OK--> Sending: ATS0=0 OK--> Sending: AT+CGDCONT=1,“IP”,“cmnet”
