Daniel, I must have missed your response several weeks ago. I've read several of the posts including the patch notes from Peter Hurley. This patch sounds very much like it would address the problem I am having. I can pair and connect the device upon the initial pairing, but subsequent connections fail. In order to connect again, I have to delete the pairing and re-pair. I have two Samsung headsets both of which are based on BT v2.1 + EDR, using Secure Simple Pairing (SSP). Both headsets have the same issue in Ubuntu 11.10 with Linux Kernel v3.0. I did not have the issue with either headset in Ubuntu 11.04 based on Linux Kernel v2.6.38. Do you know if this patch will be applied to the Linux Kernel used by Ubuntu 11.10 (v3.0)? If not, could you provide some guidance on how to go about downloading and applying the patch to my current Ubuntu installation? I am not super technical, so if you can help me figure out how to apply the patch, I can at least report back whether or not this resolves my issue. Thanks again for your help.
