Bluetooth adapter Edimax BT-8500 is not working on Debian 12 Stable

Hi. Yesterday I've installed Debian 12 and my BT adapter Edimax BT-8500 is not working. In GNOME Settings it says that bluetooth is turned off, the toggle does nothing. On Ubuntu is works like a charm, but not on Debian.

Code:dmesg:

PS.
I changed adapter to ASUS BT-400 to check if it's gonna work, and GNOME searches for devices, my TV shows up properly, but my headphones not. For BT-400 I followed that instruction:
https://gist.github.com/ssledz/69b7f...c155e244fdf7d8
But it changed nothing besides there were no errors in dmesg after that.

For all of this I'm redirecting adapters to KVM with the same Debian 12 to don't mess up my actual installation.
Any help appreciated!
