我购买了这台戴尔电脑，没有安装蓝牙保护装置，最近才购买并在主板上安装了蓝牙卡，但仍然出现“未找到适配器”的信息 - 我迷路了，陷入了困境！

答案1
制定本地 udev 规则gksudo gedit /etc/udev/rules.d/60-bluetooth-hid2hci.rules
并输入以下内容
http://paste.ubuntu.com/10129429/plain/复制粘贴然后保存，退出 gedit，重新启动
它应该可以从错误报告中工作https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/1315290
A 在第一次粘贴时发现与您的设备相比属性不正确，请使用相同的 gksudo 命令并将整个文件替换为纯文本版本http://paste.ubuntu.com/10146840/
末尾的第 11 行需要ATTRS{bmAttributes}=="e0", \改为=="c0",\
您只需将 c 更改为 e，保存，退出，重新启动
