藍牙已停用且未顯示在 LSPCI 中 - ASUS G750JM

數據機在 14.04 上正確安裝，在安裝 ubuntu 時運作正常。它是一個 Broadcom 調製解調器，並且與 Broadcom 藍牙卡相連。但是藍牙在14.04上不起作用。 Ubuntu 說它被禁用了，我能做什麼來解決這個問題？它並沒有說它不存在，只是說即使我打開它後也已禁用。

更新：我透過執行以下命令刪除了華碩藍牙的軟塊：

$sudo modprobe -b asus-wmi
$rfkill unblock all

但它仍然在設定中被停用，我無法使用它，並且在短時間內它又恢復為停用狀態

我是否可以假設，由於它沒有在該列表中的任何位置列出藍牙，Ubuntu 只是沒有意識到我有藍牙設備？這可以解釋為什麼我幾乎嘗試了所有方法來啟用它，但它不起作用。請幫忙。

更新：

自從升級到 14.10 以來，只要我藍牙就可以工作rfkill unblock all

更新：

現在，自從我刪除了 ubuntu 並從頭開始重新安裝 14.10 後，它工作正常，沒有任何問題

如果您在破折號中輸入“藍牙”並打開藍牙應用程序，您將看到類似下面的螢幕截圖，它說

藍牙已停用

在此輸入影像描述

您需要執行rfkill unblock 3，然後轉到藍牙應用程式視窗並將ON/OFF按鈕拖曳到右側以開啟藍牙ON，如果您想讓其他設備看到您的藍牙設備，則需要開啟ON可見性模式。

如果您檢查終端，rfkill list 3您將看到藍牙設備現在ON
