如何使用 ASUS PCE-AC55BT PCI-E 卡在 Ubuntu 19.10 上使用蓝牙?

我最近安装了一张 PCI-E 卡,它可以同时提供 Wi-Fi 和蓝牙功能。以前,我通过连接到 USB 端口之一的 USB 使用蓝牙。

我正在双启动 Windows 7 和 Ubuntu。

我的 Wi-Fi 在 Ubuntu 上运行良好。我的 Wi-Fi 和蓝牙在 Windows 7 上运行良好。

操作系统:Ubuntu 19.10 内核:Linux 5.3.0-40-generic

我已经运行了我在网上找到的以下命令,它表明至少(在某种程度上)在系统上检测到蓝牙

sudo rfkill list

当我进入蓝牙设置并打开蓝牙时,没有任何反应,它只是说“打开以连接设备并接收文件传输”,而以前的设备会枚举或立即连接到我的耳机。

出了什么问题?
