USB bluetooth dongle no longer recognized

This ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode) didn't work for me until 5.something (5.8 or so?). Since then, it had been working well until I started getting the same issue after one of the latest kernel updates (a month ago or so). Is it a regression kind of bug?

Re: USB bluetooth dongle no longer recognized

I have just bought the same adapter and I am having the same problem as you. sad
I believe this is a kernel bug not specific to Arch Linux though, so we may have to wait and see if someone out there can help and fix this issue
This bug is being tracked right here: https://bugzilla.kernel.org/show_bug.cgi?id=60824
I have tried to apply the patch that Reginaldo Coimbra Vieira (https://bugzilla.kernel.org/show_bug.cgi?id=60824#c207) made but it didn't change a thing for me.
PS: I have no experience working on compiling Linux and its modules, I am learning a bit right now if I can solve this issue. Maybe I did something wrong while applying his patch.

Unfortunately, my "CSR Barrot 8041a02" still not work out of the box on kernel 5.18.16
