跑步根图Linux分布与内核4.9.16和蓝色5.43 有两个设备：罗技 MX Anywhere 2鼠标和罗技 K780键盘 两款设备均采用蓝牙 4.0 LE。无线网卡内置蓝牙适配器：英特尔双频无线 AC 8260
我遇到过一个非常有趣的用例。
sspmode为蓝牙适配器启用。两台设备都可以单独配对并且工作得很好。
重新启动、睡眠或只是断开连接并重新连接设备后，我观察到以下情况：
先连接键盘，效果很好。之后连接鼠标，两个设备都运行良好，没有任何问题。
先连接鼠标，效果也很好。连接键盘后，它声称可以
connected按bluetoothctl和blueberry小程序，但打字不起作用。
udevadm monitor对这两种情况的监控显示以下内容：
首先对于键盘：

因此，如果您不小心触摸了鼠标，第一个键盘将无法工作，除非您关闭鼠标并在连接键盘后再次打开它，否则会带来很多不便。
知道为什么会发生这种情况以及如何解决这个问题吗？
