在通过 USB 进行连接时，查找检查开发人员选项设置状态中 USB调试 打开/关闭（任何状态信息）的方法
最近检查了adb shell getprop没有结果。

答案 0 :(得分：2)
如果关闭USB调试，则无法使用ADB，因此您无法通过它获取任何信息。
要将adb与通过USB连接的设备一起使用，您必须启用 在开发人员选项下的设备系统设置中进行USB调试。
参考：
Date Object
您可以致电adb devices并查看结果。如果列表为空，则设备未启用该选项。否则结果将是这样的：
List of devices attached
XXXXXXXXXXXXXX device

unique其中 adb devices -l
List of devices attached
2e2a0cb1 device usb:338952192X product:PD2065 model:V2065A device:PD2065 transport_id:3
