[Bluez-users] Ubuntu 6.06 and bluez setup problem?

[Walt Shekrota]

Many things appear to work from install with the 6.06 Ubuntu's. I think bluez 
is probably no exception. I have been having some problem that is subtle. It 
relates to the utility starting up in client space and SDP server 
responding "invalid exchange".
Please see the pertinent listings below I hope I have included what you need.
Any help or direction greatly appreciated.
I have two dongles the one used here is Cellink BTA-3120 .... also have the 
trendnet TBW-102UB.

Kubuntu 6.06

First I insert the dongle and view the dmesg as below.
Then I setup the headset leaving it waiting to pair.
On my kde desktop I get the message "not paired" in a popup.
Could it be the setup of the  file hcid.conf? (also below)

[Bluez-users] Ubuntu 6.06 and bluez setup problem?

[Walt Shekrota]

how do I determine the proper class as used in hcid.conf
and channel as used in rfcomm.conf?

I think I have found my problem but can't confirm it yet.
I have 2 dongles 
one a Cellink BTA-3120 (not a 3000) so probably the manaufacturer has changed 
the chipset
another a trendnet 102ub
I thought this should work being it is listed in the Holtmann feature list?
Perhaps in later revisions they too changed chipset?
Or are only some of these dongles listed in the feature list usable for Linux? 
If so how do you tell?
At any rate I've chickened out before I have a box of useless dongles I'll go 
for the DBT-120 at proper revision to be sure.

If someone could kindly post some info or a confirmation I might be right it 
would be helpful. I've got to say this is one of the most difficult areas in 
the linux user arena. Somehow it has to be made more simple. 

Possibly supporting more chipsets would help. Is this a future work item?

Thanks.
-Walt
