can't add bnep0 to bridge pan0: Invalid argument

First of all I'm not completely sure if this is the right group to post to but since I get no error messages in logs, I hope nobody will feel offended.

I'm trying to create an NAP under kernel 2.6.18.2 (description from
http://bluez.sourceforge.net/contrib/HOWTO-PAN). I use an USB BT dongle from Integrated System Solution Corp. and it's been recognised as follows:

~# hciconfig -a

The problem turn up when I try (after establishing connection) to add bnep0 interface to pan0 bridge interface. After

~# brctl addif pan0 bnep0

I get:

can't add bnep0 to bridge pan0: Invalid argument

(bnep0 has IP 0.0.0.0 after ifconfig bnep0 0.0.0.0 and is up, though I get no answer on ping which I could be a routing problem actually. Also adding eth1 makes no problems).

As I said, no messages in logs, no more information. What's wrong?

you have a dongle with an invalid BD_ADDR. Return that dongle and get one which has a valid address. Dongles using this address can't be added to a bridge.

Thanks a lot for this piece of advice. I wasn't aware there are unlicensed dongles on the market. Unfortunately I can't give mine back:/ Are they somehow damaged or is it only a software problem?
