Issue:

Ubuntu 20.04 won't detect Bluetooth card and I believe it may be because the wrong driver is being used. I have a HP Spectre 360 laptop that uses an Intel® Wi-Fi 6 AX201 network card (it has Bluetooth integrated).

Analysis

dmesg command indeed detects this device (as well as the device manager in windows) [ 2.403441] iwlwifi 0000:00:14.3: Detected Intel(R) Wi-Fi 6 AX201 160MHz, REV=0x354

However lspci command detects a different Intel network device (which uses a different iwlwifi driver version) 0:14.3 Network controller [0280]: Intel Corporation Wireless-AC 9462 [8086:02f0]
