重新啟動電腦後，我的兩個 USB 裝置無法運作：滑鼠和外部 WiFi 適配器。
其他 USB 裝置（例如印表機、鍵盤或外部磁碟）都可以正常運作。然而，滑鼠和 Wifi 總是需要斷開/重新連接 - 然後它們才能按預期工作。當我完全拔掉電源線然後打開機器時，一切都正常工作。正常關機是不行的。
我環顧四周，發現了不同的建議，例如重置 USB 端口，為此我使用了這個烏斯布雷塞特utility ，它適用於我的滑鼠，儘管需要一些時間（10 秒），而拔出/插入滑鼠線會立即起作用。
切換 USB 連接埠沒有任何區別，我嘗試了不同的 USB 端口，甚至是舊的 USB 2.0 連接埠。
但它不適用於我的 WiFi 適配器。我還發現執行時它甚至沒有列出LSSB。有沒有適用於這兩種設備的解決方案？

答案1
在核心 5.5.1 中引入了一個特定的 Wi-Fi 錯誤。
它已被驗證在內核 5.6.2 中已修復，但絕對是不是已在 5.5.14 中修復。
據推測該修復將進入 5.5.15，但我還沒有看到對此的確認。
這裡是布格特拉克。
