Add to this: Huawei MateBook 13-S WRT-WX9
FreeBSD 12.2-BETA2 r365865 GENERIC amd64
$ pciconf -lcvV
none4 at pci0:0:20:3:   class=ox028000   card=0x20348086   chip=0x9df08086  
rev=0x30   hdr=0x00
vendor         = 'Intel Corporation'
device          = 'Cannon Point-LP CNV1 [ Wireless-AC ]
...

As well as the message 
iwm0: iwm_start_fw: failed 60

I also sometimes get 
iwm0: (Intel(R) Dual Band Wireless AC 9560) mem 0x94210000 - 0x9421bfff at
device 20.3 on pci0
iwm0: hw rev 0x310 fw ver 34.3125011985.0 address XX:XX:XX:XX:XX:XX
iwm0: failed to send antennas before calibration: 35
iwm_run_init_ucode: failed 35
iwm0: could not initiate scan

My device has only USB Type 3 ports for external comms | video | charging,
and whether or not iwm loads or not seems to depend on what is connected to
which of the two USB ports. With nothing in either port, and starting from
power off, wlan0 sets up OK every time (so far). What additional logs can I
send?
