我买了一台带有 USB 3 端口的新“家庭服务器”。遗憾的是，到目前为止，我无法使用位于 USB 3 外壳中的外置硬盘。
当我输入 时lsusb，设备首先显示在列表中。理论上我现在应该看到它，/dev/sdb但事实并非如此。
我观察了使用以下命令插入设备时发生的情况dmesg：

奇怪的是，似乎一开始正确检测到设备，然后多次断开连接，最后情况变得非常糟糕，设备消失了。lsusb现在不再显示外壳。
另一个 USB 3 设备（较小的硬盘）在插入时出现几个错误，但最终该设备显示为/dev/sdb
我在 64 位机器 ubuntu 16.10 上使用内核 4.9.0-040900-generic（与 4.8.* 内核有同样的问题）。
