我使用的是 Ubuntu 22.04。幾個月前，當我還在使用 20.04 時，我的機械鍵盤開始出現問題，直到那一刻為止，我的機械式鍵盤都可以正常工作。這肯定是在更新後發生的，但自從幾個月前開始以來，我無法追溯在此問題開始之前安裝了哪些更新。
重新啟動後以及將 KVM 交換器從工作筆記型電腦 (Windows) 切換到 Ubuntu 桌面後，會出現此問題。 KVM 切換器不是問題，當鍵盤直接插入桌上型電腦時也會出現問題。我的 Windows 筆記型電腦上沒有出現此問題。
問題是鍵盤被探測並且探測失敗；這種情況發生了幾十次。
來自journalctl（我已將主機名稱替換為[主機名稱]）：

我嘗試過其他鍵盤、其他 USB 連接埠和新的優質 USB 電纜，因為這種行為可能表明存在電源問題，並且我嘗試了不同的電源配置文件，但均未成功。鍵盤是 Ducky One2 RGB。
我在askubuntu、stackexchange 和其他網站上看到過各種描述類似問題的帖子，但都沒有最終的解決方案。因此，每次重新啟動後或從筆記型電腦切換到桌上型電腦後，我都會花費大量時間等待鍵盤可用。有誰知道可能是什麼原因造成的？
