已修复,请查看Launchpad 错误!
我在 Ubuntu Gnome 14.10 x64 上有一个非常奇怪的问题。我的内部 WiFi/蓝牙适配器被检测到并且 WiFi 工作正常。它的蓝牙功能也被检测到,所有 GUI 和命令行命令似乎都正常工作(它们没有返回错误),但没有检测到其他蓝牙设备,其他设备也看不到我的笔记本电脑。我怀疑是天线问题(症状相同),但在 Windows 8.1 中它运行良好。
我的笔记本电脑是 Acer Aspire E3-111-C1LY

你能后的结果lsusb,并hciconfig --all因为有那还不支持正确部分芯片组
我能够修补几个模块,以便您的蓝牙应该在 14.10 和 3.16.0-28 64 位内核中工作,uname -a希望它也显示 x86_64
可以找到压缩的新模块https://www.dropbox.com/s/kufg12cf28eh36l/Ubuntu1410.zip?dl=0 将它们解压到桌面然后在终端sudo mv /lib/modules/3.16.0-28-generic/kernel/drivers/bluetooth/ath3k.ko /lib/modules/3.16.0-28-generic/kernel/drivers/bluetooth/ath3k.ko.bak
sudo modprobe -r btusb
sudo mv /lib/modules/3.16.0-28-generic/kernel/drivers/bluetooth/btusb.ko /lib/modules/3.16.0-28-generic/kernel/drivers/bluetooth/btusb.ko.bak
cd Desktop
cd Ubuntu1410
sudo cp btusb.ko /lib/modules/3.16.0-28-generic/kernel/drivers/bluetooth/btusb.ko
sudo cp ath3k.ko /lib/modules/3.13.0-39-generic/kernel/drivers/bluetooth/ath3k.ko
sudo apt-get install linux-firmware
sudo modprobe ath3k
sudo modprobe btusb

运气好的话,它会起作用,因为我没有像在 14.04 中那样在 14.10 中看到 xhci 故障加载固件
新编辑 2015 年 1 月 1 日,一种不同的方法,修补了 ath3k.c 和 btusb.c 文件 编辑:下载此https://www.dropbox.com/s/ajxndivy4vwgapv/test.zip?dl=0并将其解压缩到/home 所以你在 home 中有一个名为 test 的文件夹,然后在终端中
sudo apt-get install build-essential
cd test
cp /usr/src/linux-headers-$(uname -r)/Module.symvers Module.symvers
make all
sudo modprobe -r ath3k
sudo modprobe -r btusb
sudo mv /lib/modules/$(uname -r)/kernel/drivers/bluetooth/ath3k.ko /lib/modules/$(uname -r)/kernel/drivers/bluetooth/ath3k.ko.bak
sudo mv /lib/modules/$(uname -r)/kernel/drivers/bluetooth/btusb.ko /lib/modules/$(uname -r)/kernel/drivers/bluetooth/btusb.ko.bak
sudo cp ath3k.ko /lib/modules/$(uname -r)/kernel/drivers/bluetooth/
sudo cp btusb.ko /lib/modules/$(uname -r)/kernel/drivers/bluetooth/
