something that might be relevant:

I'm guessing the 'Opcode 0x0c03 failed' and 'Port 007: Dev 005, If 2,
Class=Wireless, Driver=[none], 480M'   are to blame here?

I've done a lot of searching and troubleshooting, but couldn´t find anything
about this particular device ID:  13d3:3585   

bluetoothctl  gives me:
[bluetooth]# list
[bluetooth]# 
any other command will give: "no default controller available".

systemd bluetooth.service is enabled.

Let me know if more info is needed (I don´t do this every day),  or if I should
contact a maintainer directly.
