4、             Linux内核的配置与修改
4.1、linux内核配置
make menuconfig
Device Drivers  ---> 
[*] Network device support  --->
   PPP (point-to-point protocol) support
[*]     PPP multilink support (EXPERIMENTAL)
[*]     PPP filtering
     PPP support for async serial ports
     PPP support for sync tty ports
     PPP Deflate compression
     PPP MPPE compression (encryption) (EXPERIMENTAL)
     PPP over Ethernet (EXPERIMENTAL)
  [*] 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 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 access the original
# install storage)

DisableSwitching=0

# Enable logging (results in a extensive report file in /var/log, named
# "usb_modeswitch_"

EnableLogging=0
