A descrição do problema
Não consigo conectar o PXC550 novamente ao bluetooth 8265 da Intel. Até agora funcionou perfeitamente por muitos meses. Agora, provavelmente depois de alguma atualização, parou de funcionar.
Se eu desemparelhar o PXC550 do meu Linux Debian (Trixie) e refazer o pareamento/confiança novamente, ele funcionará (mesmo por meio de reinicializações). No entanto, se eu desligar o notebook, ele não conectará novamente (somente após fazer todo o procedimento de desemparelhamento e pareamento novamente).
A princípio pensei que pudesse ser um firmware "novo", mas depois que tentei um firmware mais antigo o problema foi exatamente o mesmo.

O estranho é que mesmo após o pareamento/confiança bem-sucedido, recebo um erro, mas a conexão funciona:

A configuração bluetooth (@debain Trixie)
O /etc/bluetooth/main.confé praticamente estoque. Alguns usuários relataram sucesso com a mudança do ControllerModeque não fez nada. Eu tentei o ControllerModecom valores dual, bredr, le.
Tentei brincar com o /etc/bluetooth/inputmas nada ajudou. Tentei essas combinações de parâmetros:
LEAutoSecurity=true/false,UserspaceHID=true/false
Nenhuma mudança :/.
Alguém tem alguma ideia de como depurar melhor ou sabe como consertar?
