果然多了一个usb网卡

# ifconfig
enp0s20f0u3u3c2: flags=4099  mtu 1500
        ether 02:1e:10:1f:00:00  txqueuelen 1000  (Ethernet)

        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

static int is_rndis(struct usb_interface_descriptor *desc)
{
        return (desc->bInterfaceClass == USB_CLASS_COMM &&
                desc->bInterfaceSubClass == 2 &&
                desc->bInterfaceProtocol == 0xff);
}

是通过Class来判断加载什么驱动

static const struct usb_device_id option_ids[] = {
...
     { USB_VENDOR_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x06, 0x06) },
...
     { USB_VENDOR_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x06, 0x10) },

通过配置信息加载串口驱动

晕, 不同设备,同PID
net/usb/cdc_mbim.c: /* Some Huawei devices, ME906s-158 (12d1:15c1) and E3372

查询串口配置

/dev/ttyUSB0     AT命令+Modem
/dev/ttyUSB2     AT命令口

华为这个模块,用picocom , 模块返回的信息 显示不全
用microcom才行

 microcom -s 115200 -p /dev/ttyUSB2 -d -l /tmp/hw.log


AT+CGDCONT?
返回
+CGDCONT: 0,"IPV4V6","","",0,0,0,0,0,0
+CGDCONT: 1,"IP","3gwap","",0,0,0,0,0,0
+CGDCONT: 11,"IPV4V6","","",0,0,0,0,0,0




AT^NDISDUP?
返回
OK




AT^NDISDUP=?
返回
^NDISDUP: (1-11),(0-1)

OK


开始连接
AT^NDISDUP=1,1
返回
OK


发完 AT^NDISDUP=1,1 然后就能分配到IP了

# udhcpc -i enp0s20f0u3u3c2:
udhcpc (v1.22.1) started
Sending discover...
Sending select for 172.17.128.75...
Lease of 172.17.128.75 obtained, lease time 518400

其它AT命令


AT+CFUN?
响应
+CFUN: 1

OK
---
AT+CGATT?
响应
+CGATT: 0

OK
---
AT+CGACT?
响应

+CGACT: 1,1
+CGACT: 11,0
+CGACT: 21,0
+CGACT: 22,0
+CGACT: 23,0
+CGACT: 24,0
+CGACT: 25,0
+CGACT: 26,0
+CGACT: 27,0
+CGACT: 28,0
+CGACT: 29,0
+CGACT: 30,0
+CGACT: 31,0

OK

路由器上
先发送 AT^NDISDUP=1,1 ,让后等待 AT+CGATT? 返回1(大约20-30秒)

关闭主动信息上报

AT^CURC=0

comgt中 华为的私有命令 “AT^”都要进行转义 “AT\^”
