通常遇到adb连接手机出现offline一般都是以下几个步骤解决问题：

adb kill-server && adb start-server
adb reconnect offline 多次
检查端口5037占用，排除改名的adb
换USB线和USB口拔插
重启手机
重装驱动
撤销usb授权重试
关闭开发者模式再开启
切换adb版本尝试
上面几步之后不管用，更换adbkey和adbkey.pub

但是我遇到的现象就比较奇特了，是一台笔记本上部分手机出现问题，上面的步骤完全不管用，最奇特的是跟会传染一样，开始一台手机出现问题，后来接下来另外两台手机出现问题，再后面更严重，直接台式机也出现这样的情况，看样子不是电脑的问题，是手机系统本身有bug，我的某些使用习惯触发这个bug，于是查看adb连接日志

可以从日志看出完全是手机端出现问题，究竟是什么原因导致的只能靠猜，于是我去开发者模式里面一边切换连接模式，一边查看日志，发现这个操作能解决问题，但是不能阻止问题出现。
