问题：

Ubuntu 20.04 无法检测到蓝牙卡，我认为这可能是因为使用了错误的驱动程序。我有一台 HP Spectre 360​​ 笔记本电脑，它使用 Intel® Wi-Fi 6 AX201 网卡（它集成了蓝牙）。

分析

消息命令确实检测到了该设备（以及 Windows 中的设备管理器） [ 2.403441] iwlwifi 0000:00:14.3: Detected Intel(R) Wi-Fi 6 AX201 160MHz, REV=0x354

然而串行通信命令检测到不同的英特尔网络设备（使用不同的 iwlwifi 驱动程序版本）0:14.3 Network controller [0280]: Intel Corporation Wireless-AC 9462 [8086:02f0]
