蓝牙不会打开联想G510的Ubuntu14.04LTS

它昨天才开始工作，现在我看到条子上那个灰暗的图标，而启用蓝牙就什么都不做了。我检查了rfkill，它没有被封锁。
dmesg | grep Blue会产生这样的结果：

有什么想法吗？
编辑:添加了lsusb的结果；lspci -nnk _ grep -iA2网；dmesg \ grep -i固件；dmesg _ grep -e -e Atheros -e Broadcom；uname -a；hciconfig -a

这可能需要我以前的工作
echo "blacklist ath3k" | sudo tee /etc/modprobe.d/ath3k.conf然后编辑rc.local sudo -H gedit /etc/rc.local
再加上几行，最后3行是
sleep 45
modprobe ath3k
exit 0保存、退出和重新启动
