我使用的是 HP 250 G3 笔记本电脑，装有 Ubuntu 15.04 32 位。但我无法使用蓝牙服务。它显示“未找到蓝牙适配器”。我的蓝牙状态显示：

我也是 HP 250 G3 用户。目前使用的蓝牙驱动程序是 Ralink rt3290。我使用下面链接中的模块成功使蓝牙正常工作。
https://www.github.com/dineshraj01/rtbth-dkms
您需要使用下面给出的命令来编译并安装它
make
sudo make install
对我来说非常有效。有时重启后蓝牙不起作用。您只需使用以下命令删除并再次添加模块即可。
sudo rmmod rtbth
sudo modprobe rtbth
您还可以阅读给出的 github repo 上的说明:)
