Eu tinha um dongle BT que funcionava no meu PC com o Xubuntu 14.04. Agora eu tenho o Xubuntu 16.04 e ele não funciona mais. Eu uso este dongle apenas 5 ou 6 vezes por ano, por isso não tenho 100% de certeza se funcionou em 16.04 ou não.
Não importa qual porta usb o dongle esteja conectado: o problema é o mesmo.
O dongle funciona em um PC com Windows 7
Algumas coisas abaixo para que você possa entender o meu problema.
