按照文档将移远提供的qmi_wwan_q.c 加入到内核目录，看不到 /dev/cdc-wdm 设备
EC800M 不需要QMI_WWAN，quectel-CM拨号会使用tty AT 串口。
一般使用cdc_ether
我是参考的这个文档：
Quectel_LTE&5G_Linux_USB_Driver_User_Guide_V2.0.pdf
不需要QMI_WWAN 的话，还需要用 quectel-CM 程序拨号上网吗？
另外请教怎么使用 cdc_ether 上网？
ls /sys/bus/usb/drivers
asix cdc_wdm qmi_wwan usbhid
ax88179_178a ftdi_sio qmi_wwan_q usblp
cdc_acm hub uas usbserial
cdc_ether net1080 usb usbserial_generic
cdc_ncm option usb-storage zaurus
cdc_subset pl2303 usbfs
我目前能看到cdc_wdm的驱动的，不知道为什么看不到 /dev/cdc-wdm?
这个模组不支持QMI_WWAN.
使用cdc_ether 请将模组配置成ECM mode
AT+QCFG=“usbnet”,1
重启生效。
那个USB 驱动的2.0 版本的文档已经是很久以前的，那时候还没有EC800M。
usb0 没有配置ip地址，请教下什么原因

我之前用的default.script 和你给我的差不多，用的是老版本的拨号程序目录下的
不是一定要放到/etc/udhcpc/
busybox udhcpc --help
看看默认应该放哪里。
默认是 /usr/share/udhcpc
需不需要修改拨号程序代码，代码里好像没有udhcpc 没有指定 -s 参数
就看这里有没有调用你的default.script
如果没有调用到，可以修改下default.script 的位置或者去改下quectel-CM 的源码 udhcpc.c .
dhcp 的打印会出个错误：route: SIOCDELRT: No such process 这个有没有影响？

两个位置都有试过，/etc/udhcpc 和 /usr/share/udhcpc 。用ifconfig usb0 都没有看到配置ip。
如果调用脚本是有打印的吧？
始终没看到打印，不太清楚udhcpc应用调用 default.script 的机制。但是看quectel-CM源码里面只有
busybox udhcpc -f -n -q -t 5 -i usb0 并没有-s 的参数指定。1.6.4 拨号程序是会自动调用 default.script 脚本吗？
udhcpc 会自动调用一个默认的脚本。这个逻辑可以去看下busybox 或者udhcpc的源码。
只运行busybox udhcpc -i usb0 不能将网卡的ip 地址bind 到usb0 上，要通过这个脚本，才能让ifconfig usb0 看到地址。
网卡上肯定有ip地址，没有地址就是哪里出异常了。
