Can't connect Bluetooth Devices

[Steffen Becker <steffen.becker@tu-ilmenau.de>]

Hello,

I still have a problem to connect my bluetooth devices via pand command. 
I've been searching the internet and asked in forums, but i didn't get 
an answer.

I have 2 gentoo-PCs with a Bluetooth-3.0 Dongle at each PC.
Circa 2 weeks ago, everything worked. BlueZ-4.96 was installed and I had 
no problems to connect my devices via pand and via rfcomm command.
But then I asked you for an SSP debug mode patch, because I wanted to 
sniff my rfcomm connection. At the same time BlueZ-4.99 was released and 
so I installed the new BlueZ-version and the patch.
I also deleted the stored linkkey and I was happy that I was able to 
sniff my rfcomm-connection.
But thenceforth I can't connect my devices via pand command.

Then I tried to install the BlueZ-4.99 *without* the patch, but I still 
couldn't connect via pand.
I also tried to install BlueZ-4.96, but the problem was still the same. 
So I think it's no problem of the patch or the newer BlueZ-version, but 
I really have no idea what's wrong.

If you need any of my configuration-files, just tell me and I will send it.

In the end, I show the hcidump message when I try to connect via pand 
command.

Hope anyone can help me.

Regards,
Steffen
