我尝试了蓝牙向导和 bluedevil。没有用。我尝试在运行 Fedora 17 的 Dell Inspiron 1525 上使用蓝牙耳机，使用加密狗。lsusb 列出了加密狗，如下所示：
dbus.exceptions.DBusException: org.freedesktop.DBus.Error.NoReply: Message did not receive a reply (timeout by message bus)
当我运行 hcitool scan 时，我得到：
00:11:67:00:00:23 Sport Bluetooth
当我尝试运行 blueman-manager 时，它输出：

这个问题让我抓狂。有人知道怎么解决吗？
