This post is for people getting connection errors.
Some people reported connection issues that were fixed by upgrading the linux bluetooth stack (default one in Ubuntu 10.10 is version 4.69).
Instructions if you want to do upgrade to the latest version (4.91):
System > Administration > Synaptic Package Manager
Settings > Repositories > Other SoftwareAdd
Apt Line: ppa:blueman/ppa
Close
Reload
Mark all upgrades
Apply
I just upgraded to this version and it seems not to cause any issue on my setup. Do it at your own risk!
Note: bluez version 4.91 is now in Ubuntu 11.04.
I wish I could confirm upgrading fixed it, however it did not in my case… 🙁
Thanks for posting the easy details on how to upgrade though, as I found myself into a dependency hell going about it manually.
I think I'll try if I can get another bluetooth dongle somewhere to test with that. Hopefully that can rule out any other problems on my end. Will report back when I find anything useful. 🙂
Too bad 🙁
By the way, what are the brand and the model of this dongle?
I just tried with another dongle, still no go. Note however that both dongles are from Sweex: Dongle #1 is Sweex BT211, Dongle #2 is Sweex BT202.
Here are the logs, for completeness' sake:

Oh, I just found that dongle #2 doesn't retain the changed address after I reconnect it. If I restart sixemugui it reports the changed address, but the moment I disconnect the dongle & reconnect it, the original address is restored.
Dongle #1 does retain the changed address after an unplug.
The second one has an "Integrated System Solution Corp" chip. Very few of these are reported to work.
It seems you are very unlucky 🙁
Please open an issue. I will ask you a few traces for the first dongle.
Also, if you can borrow other dongles, please test them.
