ubuntu 14.04 未找到蓝牙适配器

你好,我有一台 HP Pavillion 14 笔记本电脑,装有 ubuntu 14.04 和 windows 8.1 双启动。我的 wifi 工作正常,但 ubuntu 找不到任何蓝牙适配器。蓝牙在 windows 中工作正常。我尝试过其他几篇关于此问题的帖子,但这些解决方案都不适合我。

这是我通过 rfkill list 得到的结果

vedant@VG:~$ rfkill list
0: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no

这是我使用 lspci 获得的结果
