Problems with bluetooth headset on fedora 17

Question

I tried bluetooth-wizard and bluedevil. It didn't work. I'm trying to use my bluetooth headset on my Dell Inspiron 1525, running Fedora 17, using a dongle. lsusb lists the dongle as follows:

dbus.exceptions.DBusException: org.freedesktop.DBus.Error.NoReply: Message did not receive a reply (timeout by message bus)

When I run hcitool scan. I get:

00:11:67:00:00:23   Sport Bluetooth

When I try to run blueman-manager, it outputs:

I'm becoming insane with this problem. Does anyone knows a way to solve it?
