我将鼠标与 USB 适配器配对，并在 bluetoothctl 中信任鼠标。从睡眠状态恢复时，从 bluetoothctl 屏幕打印来看，连接似乎已成功恢复。但是鼠标无法使用。查看配对设备，鼠标不见了。在 bluetoothctl 中使用配对命令会导致 bluetoothd 出现段错误。

有时，它还会出现另一个问题：
gnome-shell[1646]: Error setting property 'Powered' on interface org.bluez.Adapter1: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name :1.226 was not provided by any .service files (g-dbus-error-quark, 2)

这是已知的错误还是我的配置有误？如果这是已知的错误，该如何解决？
