我最近安裝了一張 PCI-E 卡，它可以同時提供 Wi-Fi 和藍牙功能。以前，我透過連接到 USB 連接埠之一的 USB 使用藍牙。
我同時啟動 Windows 7 和 Ubuntu。
我的 Wi-Fi 在 Ubuntu 上運作良好。我的 Wi-Fi 和藍牙在 Windows 7 上運作良好。
作業系統：Ubuntu 19.10 核心：Linux 5.3.0-40-generic
我已經運行了我在網上找到的以下命令，它表明至少（在某種程度上）在系統上檢測到藍牙
sudo rfkill list

當我進入藍牙設定並打開藍牙時，沒有任何反應，它只是說“打開以連接設備並接收文件傳輸”，而以前的設備會列舉或立即連接到我的耳機。
出了什麼問題？
