私は問題に関する多くの投稿を閲覧していましたが、モノリシックな答えは見つかりませんでした。
問題:他のbluetoothノードを検出/検出できません。

上のスニペットでわかるように、最後の2行で-ドライバーに問題があるようです。
コンボニックについて話していることに注意してください。つまり、Wi-Fiと物理ネットワークインターフェイスカード上のBluetoothデバイスです。
問題に光を当ててください:
PDATE: iはpilot6リンクをたどり、両方のアーキテクチャについて図の手順を実行しました。すなわち、32ビットと64ビット。コンピューターをシャットダウンしましたが、問題はまだ解決していません。他の情報が必要な場合は、詳細情報を同封してください。

最初にファームウェアをインストールする必要があります。 this answer を使用して実行できます。
しかし、カーネル3.13.0-59には多くのバグがあるようです。その中には、ファームウェアをロードできないことがあります。
カーネルを3.19にアップグレードすることをお勧めします。ターミナルで実行することで実行できます
Sudo apt-get install linux-generic-lts-vivid
そして再起動します。
