Here is my take on setting up dyndbg for this issue.

P.S. Add log_buf_len=4M, to grub cmdline for reboot after the other steps.

Create a file 
```
==> /etc/modprobe.d/wifi.conf <==
options iwlwifi dyndbg="+pmfl"
options iwlmvm dyndbg="+pmfl" 
options btusb dyndbg="+pmfl"
options btmtk dyndbg="+pmfl"
options btrtl dyndbg="+pmfl"
options btintel dyndbg="+pmfl" 
options bluetooth dyndbg="+pmfl" 
```

On Debian run `update-initramfs -k all -u` to include these settings on-boot.

Many of these do not dymdbg on my system.

I'm guessing this line `iwlwifi 0000:04:00.0: Detected RF HR B3, rfid=0x10a100`
happening early causes the btusb module to be locked out of accessing the
device.
