重新启动电脑后，我的两个 USB 设备无法工作：鼠标和外部 WiFi 适配器。
其他 USB 设备（例如打印机、键盘或外部磁盘）都可以正常工作。然而，鼠标和 Wifi 总是需要断开/重新连接 - 然后它们才能按预期工作。当我完全拔掉电源线然后打开机器时，一切都工作正常。正常关机是不行的。
我环顾四周，发现了不同的建议，例如重置 USB 端口，为此我使用了这个乌斯布雷塞特utility ，它适用于我的鼠标，尽管需要一些时间（10 秒），而拔出/插入鼠标线会立即起作用。
切换 USB 端口没有任何区别，我尝试了不同的 USB 端口，甚至是旧的 USB 2.0 端口。
但它不适用于我的 WiFi 适配器。我还发现执行时它甚至没有列出LSSB。有没有适用于这两种设备的解决方案？

答案1
内核 5.5.1 中引入了一个特定的 Wi-Fi 错误。
它已被验证在内核 5.6.2 中已修复，但绝对是不是已在 5.5.14 中修复。
据推测该修复将进入 5.5.15，但我还没有看到对此的确认。
这里是布格特拉克。
