我的笔记本电脑上装有 Ubuntu 15.04 和 Android Studio。我可以通过 USB 数据线在 Nexus 5X 手机上工作。最近，我升级到了 Ubuntu 16.04。现在系统无法识别通过 USB 数据线连接的手机。
我有文件 /etc/udev/rules.d/51-android.rules，其中有一行，
SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", MODE="0666", GROUP="plugdev"
通过 USB 线连接时，正在充电。但 lsusb 输出未显示手机。
$ lsusb

adb devices 命令也没有显示任何设备。
系统日志有一些信息。

如何解决这个问题？任何帮助都将不胜感激。
答案1
可能是连接手机和 PC 的电缆有问题。使用另一根电缆和最新的 Ubuntu 16.04 软件，我能够将手机连接到 PC 并从 Android Studio 访问手机。
