USB_ModeSwitch for Android 7下载: https://download.csdn.net/download/sunrain_hjb/10573201
测试环境：APQ8096、Android 7(userdebug)、HUAWEI E8372
测试步骤：
1.插入HUAWEI E8372模块并稍等片刻，运行lsusb命令检测模块状态，12d1:1f01即为HUAWEI E8372，此时为Stroage模式。
msm8996:/sys/bus/usb/devices # lsusb
Bus 001 Device 004: ID 12d1:1f01
Bus 001 Device 001: ID 1d6b:0002
Bus 002 Device 001: ID 1d6b:0003
2.运行命令 adb shell usbmodeswitch -W -v 12d1 -p 1f01 -M '55534243123456780000000000000011062000000101000100000000000000" 切换模式
adb shell usbmodeswitch -W -v 12d1 -p 1f01 -M '55534243123456780000000000000011062000000101000100000000000000' Take all parameters from the command line * usb_modeswitch: handle USB devices with multiple modes * Version 2.5.2 (C) Josua Dietze 2017 * Based on libusb1/libusbx !

3.再次运行命令lsusb，检测切换后的状态，12d1:14db即切换为Modem模式后的HUAWEI E8372
msm8996:/sys/bus/usb/devices # lsusb
Bus 001 Device 005: ID 12d1:14db
Bus 001 Device 001: ID 1d6b:0002
Bus 002 Device 001: ID 1d6b:0003
对应的dmesg信息如下:

4.运行ifconfig命令，查看eth0的状态，并对比连接PC端时的状态
5.运行route和ping等命令，检查网络连接
msm8996:/ # route -n

192.168.8.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
6.在Chrome浏览器中测试网络连接，具体如下图所示。
