Ubuntu 15.04 - 蓝牙 - 未找到适配器 - Dell Precision M4800

升级到 Ubuntu 15.04 后，我发现我的机器上的蓝牙被禁用了。我继续启用了蓝牙，但从那时起，我的 Blueman 蓝牙管理器就无法帮助我设置设备了。

我的配置细节：

sudo service bluetooth status：

根据 Jerry 的反馈，该问题已得到解决，请使用以下 dmesg | tail dump 进行验证

答案1

应该很容易

sudo apt-get install linux-headers-generic build-essential
wget https://www.dropbox.com/s/3jqigkapf383tod/bluetooth-15.04.tar.gz
wget https://www.dropbox.com/s/qgcu075lvvzq690/BCM20702A0-413c-8143.hcd
sudo cp BCM20702A0-413c-8143.hcd /lib/firmware/brcm/
tar -zxf bluetooth-15.04.tar.gz
cd bluetooth
cp /boot/config-$(uname -r) .config
cp /usr/src/linux-headers-$(uname -r)/Module.symvers Module.symvers
make -C /lib/modules/$(uname -r)/build M=$PWD modules
sudo cp btusb.ko /lib/modules/$(uname -r)/kernel/drivers/bluetooth/
sudo modprobe btusb

然后检查固件是否已加载，dmesg | tail请将其发布在评论中或编辑您的问题以包含

echo btusb | sudo tee -a /etc/modules

当你的内核更新时，蓝牙将会失败，直到你

cd bluetooth
make -C /lib/modules/$(uname -r)/build M=$PWD clean
cp /boot/config-$(uname -r) .config
cp /usr/src/linux-headers-$(uname -r)/Module.symvers Module.symvers
make -C /lib/modules/$(uname -r)/build M=$PWD modules
sudo cp btusb.ko /lib/modules/$(uname -r)/kernel/drivers/bluetooth/
sudo modprobe -r btusb
sudo modprobe btusb
