华硕 X555LN (14.10) 上的蓝牙无法使用

我需要帮助解决我的笔记本 Asus X555LN 的问题，Ubuntu 似乎没有蓝牙适配器。在 Windows 上它可以正常工作，但在 Ubuntu 14.10 上却不行。我安装了 blueman，但我的蓝牙仍然无法工作。

以下是 lsusb 的结果

你的设备尚未被 Ubuntu 内核支持，但这不是问题

wget https://www.dropbox.com/s/xbmm9vfg2fby2zn/fw-04ca_2006.hcd
sudo cp fw-04ca_2006.hcd /lib/firmware
sudo cp fw-04ca_2006.hcd /lib/firmware/brcm/BCM43142A0-04ca-2006.hcd

wget https://www.dropbox.com/s/dnlvxmw5l7mwn2d/bluetooth.tar.gz
tar -zxvf bluetooth.tar.gz
cd bluetooth
sudo apt-get install linux-headers-generic build-essential
cp /usr/src/linux-headers-$(uname -r)/Module.symvers Module.symvers
cp /boot/config-$(uname -r) .config
make -C /lib/modules/$(uname -r)/build M=$PWD modules
sudo modprobe -r btusb
sudo cp btusb.ko /lib/modules/$(uname -r)/kernel/drivers/bluetooth/
sudo modprobe btusb

您可能需要重新启动，它应该适用于当前内核。如果您进行了更新，并且您的蓝牙在重新启动后再次停止工作，则您可能已更新内核，然后执行以下操作

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

编辑：因为 xhci 似乎存在问题

echo "blacklist btusb | sudo tee /etc/modprobe./btusb.conf

gksudo gedit /etc/rc.local

然后在上面添加两行，exit 0这样最后三行就是

sleep 40
modprobe btusb
exit 0

保存，退出并重启
