I had the same issue and found the problem: Android Studio.
我遇到了同样的问题并发现了问题：Android Studio。
Open the Android Studio menu Tools-> Androidand uncheck Enable ADB integration.
打开 Android Studio 菜单Tools->Android并取消选中Enable ADB integration。
adb devicesshould work (you might need adb kill-serverfirst).
adb devices应该工作（您可能adb kill-server首先需要）。
Then you can re-enable ADB integration in Studio.
然后您可以在 Studio 中重新启用 ADB 集成。

I recently got the same error, after installing a driver for the Moto X. I previously had the ADB and Fastboot quick install. I installed the driver, saw that the Moto X still wasn't registered, so uninstalled the driver again. Ten I got this error message. I opened Task Manager, killed the ADB.exe and then in Bash hit the adb devicecommand. All was good again.
在为 Moto X 安装驱动程序后，我最近遇到了同样的错误。我之前安装了 ADB 和 Fastboot 快速安装。我装了驱动，发现Moto X还没注册，又卸载了驱动。十我收到此错误消息。我打开了任务管理器，杀死了 ADB.exe，然后在 Bash 中点击了adb device命令。一切又好了。

This typically means, that your ADBservice or your driver is outdated.
Since the drivers aren't updated most of the time, make sure you've installed the latest version of your Android SDK Platform-tools via the SDK Manager:
这通常意味着您的ADB服务或您的驱动程序已过时。
由于驱动程序大部分时间都不会更新，请确保您已通过 SDK 管理器安装了最新版本的 Android SDK 平台工具：
