NanoPi H3配置USB-OTG口为以太网卡

系统：h3-sd-friendlycore-focal-4.14-armhf-20210618.img

1.将原有的g_mass_storage.conf配置注释掉

mv /etc/modules-load.d/g_mass_storage.conf /etc/modules-load.d/g_mass_storage.conf.bk

2.添加自动加载g_ether模块配置文件

echo "g_ether" >> /etc/modules-load.d/g_ether.conf

3.配置udev服务，用于自动配置usb0接口IP

nano /etc/udev/rules.d/99-usb0.rules

内容：

---------------------------------------------------------------------------------------------------------------------

SUBSYSTEM=="net", ACTION=="add", KERNEL=="usb0", RUN+="/root/configure_usb0.sh"

-----------------------------------------------------------------------------------------------------------------------

nano /root/configure_usb0.sh

内容：

------------------------------------------------------------------------------------------------

#!/bin/sh

# Wait for usb0 interface to become available
while ! ip link show usb0; do
    sleep 1
done

# Configure usb0 interface with a static IP address
ip addr add 192.168.7.2/24 dev usb0
ip link set usb0 up

# Optional: Configure default gateway (if needed)
# ip route add default via 192.168.7.1 dev usb0

echo "usb0 interface configured with IP 192.168.7.2"
----------------------------------------------------------------------------------------------

chmod +x /root/configure_usb0.sh

4.重新启动nanopi

ifconfig
