硬件平台：MT7628A

openwrt版本：MTK_SDK

1、添加模组信息

/build_dir/target-mipsel_24kc_musl/linux-ramips_mt76x8/linux-4.14.180/drivers/usb/serial/option.c

在源码中找到option_ids数组， 添加模组VID、PID: 0x1c9e、 0x9b3c

/* 4G Systems products */

/* This is the 4G XS Stick W14 a.k.a. Mobilcom Debitel Surf-Stick *

 * It seems to contain a Qualcomm QSC6240/6290 chipset            */

#define FOUR_G_SYSTEMS_PRODUCT_W14        0x9603

#define FOUR_G_SYSTEMS_PRODUCT_W100        0x9b01

/* Fujisoft products */

#define FUJISOFT_PRODUCT_FS040U            0x9b02

/* iBall 3.5G connect wireless modem */

#define IBALL_3_5G_CONNECT            0x9605

/* Zoom */

#define ZOOM_PRODUCT_4597            0x9607

/* SpeedUp SU9800 usb 3g modem */

#define SPEEDUP_PRODUCT_SU9800            0x9800

/*U9300*/
#define LONGSUNG_VENDOR_ID            0x1c9e

#define LONGSUNG_U9300_PRODUCT_ID     0x9b3c

添加该id到数组，过滤 interface 4

{ USB_DEVICE_INTERFACE_CLASS(LONGSUNG_VENDOR_ID, SPEEDUP_PRODUCT_SU9800, 0xff) },

{ USB_DEVICE_INTERFACE_CLASS(LONGSUNG_VENDOR_ID, LONGSUNG_U9300_PRODUCT_ID, 0xff),

   .driver_info = RSVD(4) },

{ USB_DEVICE_INTERFACE_CLASS(LONGSUNG_VENDOR_ID, 0x9801, 0xff),

在 /drivers/network/usb/qmiw_wan.c文件添加 VID

2、编译

配置make menuconfig：

Base system --> udev
Kernel modules --> USB Support --> kmod-usb-acm kmod-usb-net kmod-usb-net kmod-usb-net kmod-usb-net-qmi-wwan kmod-usb-ohci kmod-usb-serial kmod-usb-serial-option
LuCI ---> Protocols ---> luci-proto-3g luci-proto-qmi
Network ---> uqmi
Utilities ---> usb-modeswitch usbutils

配置make kernel_menuconfig：

device drivers ---> usb support --->usb serial converter support--->USB driver for GSM and CDMA modems
device drivers--->Network device support--->usb Network Adapters--->Multi-purpose USB Networking Framework

修改 ENOMSG值改为42

build_dir/target-mips_34kc_uClibc-0.9.33.2/linux-ar71xx_generic/linux-3.18.84/arch/mips/include/uapi/asm/errno.h

#define ENOMSG 42

编译后, 添加成功 及 驱动正常 会在 /dev/ 目录下生成 ttyUSB0 -- ttyUSB4   5个端口

3、编译龙尚gobinet驱动

将官方驱动解压到 package/gobinet/src/，在package/gobinet 目录下新建 makefile 文件，内容如下：

include $(TOPDIR)/rules.mk

include $(INCLUDE_DIR)/kernel.mk

PKG_NAME:=gobinet

PKG_RELEASE:=1

include $(INCLUDE_DIR)/package.mk

define KernelPackage/gobinet

    SUBMENU:=Other modules

    TITLE:=Support Module for gobinet

    DEPENDS:=+kmod-usb-core +kmod-usb-net

    FILES:=$(PKG_BUILD_DIR)/GobiNet.ko

    AUTOLOAD:=$(call AutoLoad,81,GobiNet)

endef

define KernelPackage/gobinet/description

    This is a gobinet drivers

endef

MAKE_OPTS:=ARCH="$(LINUX_KARCH)" \

    CROSS_COMPILE="$(TARGET_CROSS)" \

    SUBDIRS="$(PKG_BUILD_DIR)"

define Build/Prepare

    mkdir -p $(PKG_BUILD_DIR)/

    $(CP) -R ./src/* $(PKG_BUILD_DIR)/

endef

define Build/Compile

    $(MAKE) -C "$(LINUX_DIR)" $(MAKE_OPTS) modules

endef

$(eval $(call KernelPackage,gobinet))

在menuconfig 中将该驱动编译进内核  kernel modules ->   Other modules ->  kmod-gobinet

编译刷机后查看是否出现新的网卡eth0或者eth1

4、查看模块状态，拨号上网(安装minicom，选择ttyUSB2)

minicom操作：

查询APN

AT+CGDCONT?

配置APN

AT+CGDCONT=1,"IP","CTNET"

CTNET(电信)

CMNET(移动)

3GNET（联通）

APN一般模块可以自动识别，无需配置


拨号上网

AT$QCRMCALL=1,1

加入开机启动 rc.local，注意文件需要可执行权限

echo -e "at\$qcrmcall=1,1\r\n" >/dev/ttyUSB2 | cat /dev/ttyUSB2

修改路由配置文件vi /etc/config/network

config interface 'wan'

    option  device '/dev/cdc-wdm0'

    option proto 'qmi'

    option apn  'cnnet'

    option username 'card'

    option password 'card'

    option ifname 'wwan0'

WEB页面添加新的wan接口：

登录web页面，network ->  interfaces，点击 add new interfaces ，任意起个名字，DHCP CLIENT,  interface选择新的网口eth*，firewall  加入wan，刷新后看是否能够自动获取ip,获取ip成功即可联网！
