Thanks. I was just looking into this further and found this link which looks 
like the trouble I'm having:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/39414

specifically:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/39414/comments/47


I have the same message flood. My guess was the dongle supports esco, while 
the headset doesn't (because it's not in the feature set). Is this not 
the same issue? Here, the headset:

Requesting information ...
         BD Address:  00:1A:45:01:F9:42
         Device Name: Jabra BT135

I have to leave for the day in about 60 minutes. I'll give the patch a try but 
it might be tonight before I report back (depending on how fast I can build 
kernels). Last night I went with 2.6.23.17 instead of 2.6.24.3, 
but I'd really like to see my headset working under 2.6.24.x kernels.
