Re: bluetooth hci0: firmware: failed to load brcm/BCM20702A1-0a5c-21e6.hcd
It might be that the heart of the problem could be:
# hciconfig hci0 up
Can't init device hci0: Invalid request code (56)
And that consequently, at some point, "btusb" could be unloaded, with the
consequence that
hciconfig --all
wouldn't show anything anymore.
If I put that point aside... Some things are working:
# systemctl status bluetooth
● bluetooth.service - Bluetooth service

But hci0 can't be brought up, and therefore nobody can see it,
starting with bluetoothctl.
I might have gathered sufficient information to take that issue to bluez-devel
mailing list.
