Clearly I am stealing the thread but I also have a problem with bluetooth in 
Fedora 33 and I unable to point what is the problem.

I have followed the instruction at
https://fedoraproject.org/wiki/How_to_debug_Bluetooth_problems 

# hciconfig
hci0:   Type: Primary  Bus: USB
        BD Address: xx:xx:xx:xx:xx:xx  ACL MTU: 1021:6  SCO MTU: 255:12
        DOWN
        RX bytes:1566 acl:0 sco:0 events:170 errors:0
        TX bytes:35258 acl:0 sco:0 commands:170 errors:0

Trying to bring it to a working state does not work either:

# hciconfig up

shows the same output as above.

# lsusb | grep -i blue
Bus 003 Device 002: ID 13d3:3548 IMC Networks Bluetooth Radio

This pair shows up in drivers/bluetooth/btusb.c

Yet something seems to go awry since:

# systemctl status bluetooth
● bluetooth.service - Bluetooth service
     Loaded: loaded (/usr/lib/systemd/system/bluetooth.service; enabled; vendor 
preset: enabled)
     Active: active (running) since Wed 2020-12-02 07:02:48 WET; 7h ago

The last part does not look right.
But is it a problem of the kernel or the daemon?

Any help is appreciated
