I have following model of bluetooth dongle:


Bus 005 Device 004: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle
(HCI mode)

and produces following failed mode status:

The dongle is not getting connected in the following kernel versions:
5.13.9-100.fc33.x86_64
5.13.10-100.fc33.x86_64
5.13.12-100.fc33.x86_64

It worked couple of months before so it should be working in the kernel
kernel-5.13.6-0. 

Let me know if you need any other information.
