当我连接耳机时，它会禁用鼠标、键盘或两者。有趣的是，当我再次断开耳机时，命令（例如来自键盘的命令）似乎突然全部通过了（例如 alt-tab）。我觉得这很诡异。发生了什么事，我怎样才能再次同时使用这 3 台设备？
更多信息：我有一台 steelseries arctis 7，它曾经与 ubuntu 18 配合得很好。它与 USB 加密狗建立无线连接。我将 ubuntu 18 升级到 20和我的主板。在这些更改之前，一切都运行良好。新主板只有 2 个 USB 端口可用，因此我使用显示器上的额外 USB 端口。断开耳机连接后，dmesg 输出包含：retire_capture_urb: 442 callbacks suppressed
更新 1：更多 dmesg -w 输出：
