我在我的 MSI GS70 2QD 笔记本电脑上运行 Ubuntu 16.04 LTS，内核是 4.13.0-32-generic。
我遇到的问题是我的计算机具有蓝牙功能，但内核无法找到蓝牙驱动程序。
当我运行时rfkill list，输出是：
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
当我运行时lsusb，输出是：

我已阅读了许多有关 AR3012 驱动程序这一确切问题的不同文章，但似乎无法找到任何可行的方法，所以要么是我做错了什么，要么是我没有完全理解我应该做什么。
如果您需要我提供更多信息来帮助我，请告诉我。

答案1
此问题是由 Atheros 对两个不同的蓝牙设备使用相同的 ID 引起的，类似于https://askubuntu.com/a/791590/300665 我在终端中为你的蓝牙设备修补了 4.13 源代码
sudo apt-get install git dkms build-essential
git clone https://github.com/jeremyb31/bluetooth-4.13-ath3004-rome.git
sudo dkms add ./bluetooth-4.13-ath3004-rome
sudo dkms install bluetooth-3004/0.1编辑也echo "blacklist ath3k" | sudo tee -a /etc/modprobe.d/blacklist.conf
重新启动
