I have a "lite" (diskless) system, with xfce. I need to use it with a bluetooth keyboard (Logitech Cordless MediaBoard Pro™ for PS®3).

On 9.04 I used hidd --search perfectly. In 11.04 or newer seems that such method does not work anymore.

I found also this guide, but it does not works for me.
I'm testing all of it also on a standard 11.04 installation, with absolutely same results.

In details:

Code:
oscar@oscarbuntu:~$ hcitool dev
Devices:
	hci0	00:02:72:C2:CF:6A
oscar@oscarbuntu:~$ sudo bluez-simple-agent hci0 00:07:61:b4:ef:a2
RequestPinCode (/org/bluez/2353/hci0/dev_00_07_61_B4_EF_A2)
Enter PIN Code: 0000    
Release
Creating device failed: org.freedesktop.DBus.Error.NoReply: Did not receive a reply.
Possible causes include: the remote application did not send a reply, 
the message bus security policy blocked the reply, the reply timeout 
expired, or the network connection was broken.

Note: the code "0000" is first inserted on pc an after on bt keyboard.
When I press enter on the keyboard "Release" appears. Wait about 18 seconds, and the error appears.
