Re: bluetooth hci0: firmware: failed to load brcm/BCM20702A1-0a5c-21e6.hcd
(note: that chipset is probably used by all recent thinkpad, which probably
show that when iphones have no jack anymore, BT might not be so much used by
Linux users)
If I do a "modprobe" (https://ubuntuforums.org/showthread.php?t=2346879)
modprobe -r btusb
modprobe btusb
I get that:

Seems nice, but actually, I do not have any adapter anymore:
root@pluto:/lib/firmware/brcm# bluetoothctl
[bluetooth]# list
[bluetooth]#
You can see that here too:

I also did that:
sudo cp /lib/firmware/brcm/BCM43142A0-0a5c-21e6.hcd /lib/firmware/brcm/BCM.hcd
Then modprobe -r and modprobe btusb
And then the result: "bluetooth.target: Unit not needed anymore. Stopping"
