Não é possível ativar a opção visibilty nas configurações do bluetooth

Question

Eu posso ligar e desligar o bluetooth, mas não consigo ativar a visibilidade do dispositivo. Por esse motivo, meu dispositivo não consegue se conectar a outros dispositivos Bluetooth. Como posso ativar a opção de visibilidade?

A saída para

lsusb; dmesg | egrep -i 'blue|firm'; hciconfig -a está abaixo.
