Asus X555LN (14.10) で Bluetooth が動作しない

私のノートパソコン Asus X555LN について助けが必要です。Bluetooth アダプターが Ubuntu に存在しないようです。Windows では問題なく動作しますが、Ubuntu 14.10 では動作しません。blueman をインストールしましたが、Bluetooth はまだ動作しません。

lsusbの結果は次のとおりです

   Bus 001 Device 002: ID 8087:8000 Intel Corp. 
   Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
   Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
   Bus 002 Device 005: ID 0bda:0129 Realtek Semiconductor Corp. RTS5129 Card Reader Controller

   Bus 002 Device 003: ID 0bda:57b5 Realtek Semiconductor Corp.

lsusb | grep Bluetoothは出力を表示しません。dmesg | grep -i blueはこれを出力します

    [   15.345862] Bluetooth: Core ver 2.19

rfkill list はこれを表示します:

お使いのデバイスはUbuntuカーネルではまだサポートされていませんが、問題はありません

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

再起動が必要かもしれません。再起動後にBluetoothが再び機能しなくなった場合は、カーネルを更新した可能性があります。次の操作を実行してください。

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

編集: xhciに問題がある可能性があるようです

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

gksudo gedit /etc/rc.local

次に上に2行追加してexit 0最後の3行は

sleep 40
modprobe btusb
exit 0

保存して終了し、再起動する
