Eu sou um usuário do Windows tentando se adaptar ao Linux. Atualmente, estou executando o Ubuntu 16.04.
Recentemente eu mudei minha placa wireless de um Realtek RT3290 com graves problemas de conexão no Ubuntu e no Mint para um Qualcomm QCA9565, também conhecido como DELL 1705.
O problema é: eu não tenho bluetooth com nenhum cartão. Anteriormente, com o RT3290, o módulo do blutooth não podia carregar, mas eu vi algo relacionado na "lista rfkill". Agora não vejo nada! Este módulo foi instalado em um laptop Dell com Windows e a parte do bluetooth funcionou bem.
Veja algumas informações:

Você tem alguma sugestão? O estranho é que eu também tentei instalar o Windows 10, mas também não reconheci meu bluetooth.
