我有一个 WD Passport 外置硬盘，直到今天早上它还运行正常。现在当我将它连接到我的笔记本电脑时，什么都没有发生。以下是我到目前为止所做的：
lsusb检测驱动器
Bus 004 Device 006: ID 1058:0810 Western Digital Technologies, Inc.
但lsblk没有列出：

这可能是什么问题？另外，如果我需要添加更多信息，请告诉我。

根据日志显示，Linux 内核认为您的 USB 驱动器或 USB 主机控制器存在故障/损坏。如果它在同一台机器上的其他 USB 端口上工作正常，则问题出在主机控制器上。如果它在其他操作系统或内核版本上工作正常，则您应该考虑提交错误报告。
