蓝牙在使用 [0cf3:3004] Atheros 适配器的 Ubuntu 16.04 中不起作用

Question

我的笔记本电脑是 MSI GS70 Stealth Pro，它内置了 Ubuntu 似乎无法识别的蓝牙设备。

当我去System Settings > Bluetooth它说No Bluetooth adapters found。

从我在其他线程中看到的内容来看，我在这里留下了一些希望有用的信息：

rfkill 列表：

   Hard blocked: no

我该如何解决这个问题？

Answer 1

之所以存在这个问题，是因为 Atheros 重新使用了芯片 VID 和 PID。

看到这个错误报告

作为一种解决方法，您可以修补btusb.c模块并将其从 ath3k 更改为 Rome。

我已经构建了一个 DKMS 包来解决这个问题并将其上传到我的 PPA。

安装这个 deb 并重新启动。这应该可以解决问题。
