I have a HP Slate 21 that is connected to my Windows box using a USB cable.
设备上已打开USB调试开关。
将正确的%SingleAdbInterface%和%CompositeAdbInterface%条目添加到android_winusb。inf文件，我现在看到“Android ADB接口”在我的设备管理器。 但是，在命令行中运行adb devices不会显示设备。
我还有一款惠普7系列产品，在adb设备下显示得很好。
我从设备管理器中看到的唯一区别是，一个是“Android复合ADB接口”，另一个是“Android ADB接口”。
还有一个微妙的区别。在winusb中。inf文件，对于Slate 7，我有两个%CompositeAdbInterface%条目定义，但对于Slate 21，只有一个%CompositeAdbInterface%条目定义。
如何使用adb devices命令查看我的设备?

所以上面提到的方法对我没用。对我来说，有用的是在谷歌上搜索三星Galaxy Tab USB驱动程序，下载并运行应用程序，让我的设备在我使用adb设备时得到识别。因为我用的是三星Galaxy，所以我用这个链接从三星官方网站下载了usb驱动程序。你会想谷歌自己的android型号usb驱动程序

After downloading it, I ran the application to install my usb driver and then did adb devices. Make sure your Google USB driver from the Android SDK is downloaded and that your sdk is up to date as well. Also, make sure that your USB debugging mode is enable by going to Settings -> Developer Options -> then checking USB debugging. After all this, your device in the Device Manager should not have a yellow exclamation point next to it. When you run adb devices your device should show up. Hope this helps people. I literally spent hours trying to figure this out. Hopefully my answer could save you guys the hours I spent googling.

禁用并重新启用电话上的“使用调试模式”
在windows配置中，进入设备管理。检查是否看到了您的设备，以及是否安装了驱动程序。您的设备可能没有安装正确的驱动程序。
打开tethering实际上允许我在LG设备上安装和调试，这是它工作的唯一方式

那就试试adb kill-server吧
adb devices
