设备启动以后usb协议栈会检测usb hub和usb device，检测到en200a模块后 会启动netmgr 进行联网，联网完成后会进行ntp时间同步


## RNDIS 网卡调试
默认开了CONFIG_RNDIS_DEVICE_ETH宏，是通过接入windows，作为windows的网卡，和设备进行通讯。
启动后可以usb插入pc后有如下打印

```
[10:38:01.816]收←◆(cli-uart)# ###YoC###[Jun 20 2023,02:35:46]

```

设备端输入ifconfig可以看到有一个 eth0的网卡，ip为 192.168.11.10。
```
ifconfig

eth0	Link encap:eth  HWaddr 00:00:00:00:00:00
    	inet addr:192.168.11.10
	GWaddr:192.168.11.1
	Mask:255.255.255.0
	DNS SERVER 0: 208.67.222.222
```

同时，windows电脑上也会有一个rndis网卡出现，通过修改 windows上的rndis网卡在的ip，就可以和设备进行通讯了。（由于通过usb连接，没有dhcpd功能，电脑和设备都需要设置静态ip）



通过去掉 宏 CONFIG_RNDIS_DEVICE_ETH 可以配置使用 移远的4G网卡。
