我在我的全新 Thinkpad E14 上安装了 Ubuntu 20.04，直到今天它都运行良好。
我的计算机上有 2 个 USB 端口，几天前它们工作正常，但现在这 2 个端口之一无法正常工作。
当我将罗技键盘连接到有故障的端口时，它根本无法工作，没有任何亮起，甚至大写锁定也没有亮起。
当我将罗技鼠标连接到有故障的端口时，下方的光学红灯会亮起，但鼠标无法工作。
键盘和鼠标都可以在另一个运行良好的 USB 端口上使用。
现在我的键盘连接到有故障的端口，因此它无法工作，而我在正常的 USB 端口上使用鼠标。
这是我尝试过的命令：
user@machine:$ lsusb
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 003: ID 8087:0029 Intel Corp.
Bus 003 Device 002: ID 06cb:00fd Synaptics, Inc.
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 005: ID 046d:c05a Logitech, Inc. M90/M100 Optical Mouse
Bus 001 Device 002: ID 13d3:56ff IMC Networks Integrated Camera
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
所以在这里我们可以看到鼠标已连接到良好的端口并且工作良好，到目前为止这是有意义的。

这里我们只能看到鼠标，这也是有道理的，因为另一个端口显然有故障。但 ：

在这里我们可以清楚地看到鼠标和键盘，那么故障端口到底能用吗？
我不明白，我也尝试过apt update，apt upgrade甚至尝试重新启动多次，但它也不起作用。
这是怎么回事？我该怎么做才能使有故障的 USB 端口正常工作？
