adb devices - No device attached
提问by Vladi
I need to see my Nexus 7 on the adb devices list. Although I enable the "" USB debugging "" on the device, but when I try to see the "" adb devices "", then no device is attached?
我需要在 adb 设备列表中查看我的 Nexus 7。虽然我在设备上启用了“”USB调试“”，但是当我尝试查看“”adb devices“”时，没有连接设备？

I know that you've already received right answer. But for those who meet the same error I advice to look for "Revoke USB debugging authorizations" in Developers options on your device. Sometimes it really helps! Especially if everything worked fine before in another OS.
我知道你已经收到了正确的答案。但是对于那些遇到相同错误的人，我建议您在设备的开发人员选项中查找“撤销 USB 调试授权”。有时真的很有帮助！特别是如果之前在另一个操作系统中一切正常。

Case study (on my WXP SP3... yes I still use it..), phone AllView V2ViperE, Android version 5.1: If you continue to have no devices attached (although Android Composite ADB Interface is OK in Device Manager.. I mean without the yellow "!"), the root cause could be the adb server.. Workaround: download a new adb release (e.g: http://www.androidro.ro/descarca-si-instaleaza-driveri-adb-pentru-telefoanele-allview/).. I choose V1 Viper S.. unrar and run adb-setup-1.4.2.exe which will create the C:\adb\ directory:
