Eu tenho duas unidades do mesmo modelo de fone de ouvido que usam um dongle USB sem fio (Logitech H800). Cada fone de ouvido só faz o emparelhamento com seu próprio dongle, mas eu quero que o mesmo dongle funcione com ambos os fones de ouvido.
Como posso descobrir quais são as diferenças de "configuração" no lado do driver do Linux para esses dois dispositivos para ver se há algo que eu possa mudar para fazer a troca do dongle 1 entre o emparelhamento 1 e o headset 2?
