我刚刚在 msi cx640dx 上安装了 debian wheezy。我的蓝牙设备无法工作。这是一些信息。
内核版本：
$uname -r
3.2.0-4-amd64
当我使用hcitool dev它时不显示任何设备。
$ hcitool dev
Devices:
扫描后显示我没有该设备：
$ sudo hcitool scan
Device is not available: No such device
我认为以下信息可能会有所帮助。
$lsmod | grep -i blue
bluetooth 119455 12 btusb,ath3k,rfcomm,bnep
rfkill 19012 5 cfg80211,bluetooth
crc16 12343 2 ext4,bluetooth
和。

答案1
如果您的司机是阿瑟罗斯您首先需要添加 APT deb http://http.us.debian.org/debian/ testing main non-free，然后安装firmware-atheros软件包。
答案2
您需要安装以下软件包：bluetooth、bluez、libbluetooth3 以及可能的其他相关软件包。我猜你有这些。
Atheros 固件可能是问题的根源。有一个非免费的固件-Atheros 软件包，我相信，如果它确实适合您的硬件，您可以尝试一下。您可能需要对您拥有的硬件进行一些研究，并确定您需要哪个固件以及它是否可用。
一旦你让它工作，我注意到 KDE KBluedevil 蓝牙管理器无法正常工作，但 blueman 蓝牙管理器包可以正常工作。
您可能需要运行类似以下内容的命令：“sudo hciconfig hci0 sspmode 0”才能工作，可能每次都是这样。我还没有对此进行广泛的测试。
