#!/bin/sh
echo "wlan change with: " $1 $2
case "$2" in
	up)
		echo "WiFi Connected"
		# 绿灯亮
		echo default-on > /sys/class/leds/green:internet/trigger
		# 切换为主模式
		# echo host > /sys/kernel/debug/usb/ci_hdrc.0/role
		;;
	down)
		echo "WiFi Closed"

提醒：自动切换 USB 主模式可能导致无法通过 USB 连接电脑，导致变砖，需要重新刷机。如果确实需要自动 USB 模式切换，请手动取消注释。
