![蓝牙在 Ubuntu 15.04 中不起作用](https://linux22.com/image/980362/%E8%93%9D%E7%89%99%E5%9C%A8%20Ubuntu%2015.04%20%E4%B8%AD%E4%B8%8D%E8%B5%B7%E4%BD%9C%E7%94%A8.png)
我在一台 DELL XPS 13 笔记本(型号 9343,BIOS A03)上安装了 Ubuntu 15.04。我的内置蓝牙设备通过 hci 检测到,图标在任务栏中,但在扫描蓝牙设备时却找不到任何东西,而且它本身也找不到。我附上了一些信息。欢迎提出建议。

答案1
应该很容易
wget https://www.dropbox.com/s/r2pb41rhx65t9zi/BCM20702A0-0a5c-216f.hcd
sudo cp BCM20702A0-0a5c-216f.hcd /lib/firmware/brcm/
sudo modprobe -r btusb
sudo modprobe btusb
蓝牙应该可以工作
几天后,你应该能够sudo update-usbids
并且你的蓝牙设备应该被识别为蓝牙lsusb
