我使用的是 Ubuntu 22.04。几个月前，当我还在使用 20.04 时，我的机械键盘开始出现问题，在此之前，它一直运行正常。这肯定是在更新后发生的，但由于这个问题是几个月前开始的，我无法追溯在出现此问题之前安装了哪些更新。
问题出现在重新启动后，以及将 KVM 切换器从我的工作笔记本电脑 (Windows) 切换到我的 Ubuntu 桌面后。KVM 切换器不是问题，当键盘直接插入台式电脑时也会发生问题。这个问题不会出现在我的 Windows 笔记本电脑上。
问题是键盘被探测并且探测失败；这种情况发生了几十次。

我尝试过其他键盘、其他 USB 端口和一条新的优质 USB 电缆，因为这种行为可能表明存在电源问题，并且我尝试过不同的电源配置文件，但都没有成功。键盘是 Ducky One2 RGB。
我在 askubuntu、stackexchange 和其他网站上看到过各种描述类似问题的帖子，但都没有最终解决方案。因此，每次重启后或从笔记本电脑切换到台式机后，我都会花很多时间无所事事地等待键盘可用。有人知道是什么原因造成的吗？
