Comprei recentemente o cartão wireless GC-wb867d-i para o meu novo desktop. a parte wi-fi funciona bem, no entanto, o Bluetooth não importa. A seguir estão algumas informações de diagnóstico:

parece que o firmware do cartão não está funcionando. Alguém tem alguma ideia?
A propósito. Eu tenho dual os instalar nesta máquina. win10 e ubuntu 16.04 LTS. O wifi e o Bluetooth funcionam bem com o win10.
