Android 设备未显示在 adb 列表中

Android device does not show up in adb list

提问by Peter

I have a HP Slate 21 that is connected to my Windows box using a USB cable. USB debugging is enabled on the device. After adding the proper %SingleAdbInterface%and %CompositeAdbInterface%entries to the android_winusb.inffile, I now see "Android ADB Interface" in my Device Manager. However, running adb devicesat the command-line does not show the device.

我有一台 HP Slate 21，它使用 USB 电缆连接到我的 Windows 机箱。在设备上启用 USB 调试。在文件中添加正确的%SingleAdbInterface%和%CompositeAdbInterface%条目后android_winusb.inf，我现在在我的设备管理器中看到“Android ADB 接口”。但是，adb devices在命令行中运行不会显示设备。

I have another HP slate 7 that shows up just fine under adb devices.

我有另一个 HP slate 7，它在adb devices.

The only difference I see from Device Manager is that the one that works is named "Android Composite ADB Interface" and the other one is named "Android ADB Interface."

我从设备管理器中看到的唯一区别是，一个有效的名为“Android Composite ADB Interface”，另一个名为“Android ADB Interface”。

There is yet another subtle difference. In the winusb.inf file, for Slate 7 I have two %CompositeAdbInterface%entries defined but for Slate 21, there is just one %CompositeAdbInterface%entry defined.

还有另一个微妙的区别。在 winusb.inf 文件中，对于 Slate 7，我%CompositeAdbInterface%定义了两个条目，但对于 Slate 21，只%CompositeAdbInterface%定义了一个条目。

What could be wrong with my setup?

我的设置可能有什么问题？

Looks like the installed driver was in bad state. Here is what I did to make it work:

看起来安装的驱动程序状态不佳。这是我为使其工作所做的工作：

1. Delete the device from Device Manager.
2. Rescan for hardware changes.
3. List item "Slate 21" will show up with "Unknown driver" status.
4. Click on "Update Driver" and select /extras/google/usb_driver

1. 从设备管理器中删除设备。
2. 重新扫描硬件更改。
3. 列表项“Slate 21”将显示为“未知驱动程序”状态。
4. 单击“更新驱动程序”并选择 /extras/google/usb_driver

Device Manager will find the driver and warn you about installing it. Select "Yes." This time the device got installed properly.

设备管理器将找到驱动程序并警告您安装它。选择“是”。这次设备安装正确。

Note that I didn't have to modify winusb.inf file or update any other driver.

请注意，我不必修改 winusb.inf 文件或更新任何其他驱动程序。

Hope this helps.

希望这可以帮助。

While many of these solutions have worked for me in the past, they all failed me today on a Mac with a Samsung S7. After trying a few cables, someone suggested that the ADB connection requires an official Samsung cable to work. Indeed, when I used the Samsung cable, ADB worked just fine. I hope this helps someone else!

虽然这些解决方案中的许多过去对我有用，但今天它们在配备三星 S7 的 Mac 上都让我失望。在尝试了几条电缆后，有人建议 ADB 连接需要三星官方电缆才能工作。事实上，当我使用三星电缆时，ADB 工作得很好。我希望这对其他人有帮助！

In Galaxy s6 - I resolved it by: Settings -> About device -> Software info -> Build number - tap it 7 times to enable Developer options. Go back to Settings -> Developer options -> turn on USB debugging.

在 Galaxy s6 中 - 我通过以下方式解决：设置 -> 关于设备 -> 软件信息 -> 版本号 - 点击 7 次以启用开发人员选项。返回设置 -> 开发人员选项 -> 打开 USB 调试。

Go back to your terminal adb devicesand you should see the connected device. Hope that helps.

返回您的终端adb devices，您应该会看到连接的设备。希望有帮助。
