我的笔记本电脑配有 Intel 7260 Wifi 和蓝牙。Wifi 运行良好，但我无法在 Ubuntu 16.04 上将我的 Microsoft 3600 蓝牙鼠标与其配对。不过，它可以与 Ubuntu 16.10 配合使用！
因此，我立即想到通过在 Ubuntu 16.04 上升级到内核 4.8，我可以解决我的问题，但事实并非如此。
我尝试使用 UI 和蓝牙控制，但什么都没起作用。配对过程似乎很顺利，鼠标 LED 闪烁，就像正常配对一样，但最后它不动了。我注意到的是，dmesg配对失败后显示此错误：
蓝牙：已请求 SMP 安全性但不可用
所以我猜可能和这个有关。我也尝试比较 16.10 和 16.04 之间的驱动程序版本，但它们都是一样的。我不知道该怎么办。以下是一些日志：
现在我在 Ubuntu 16.04 上运行内核 4.8.0-36。

答案1
我设法让它工作了。它类似于这但一开始它无法与 sspmode 配合使用。因此，我在配对之前尝试使用 GUI 执行此操作，并且成功了。
