(AMD64 CPU, Linux v3.2) After reading here: https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/714862/comments/43 https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/714862/comments/45 http://permalink.gmane.org/gmane.linux.kernel1.73/1262485 -- that there was a firmware patch which supposedly addressed this problem, I obtained the Ubuntu "linux-firmware" package which contains the updated "ath3k-1.fw" file (as of version 1.73): http://packages.ubuntu.com/precise/linux-firmware http://changelogs.ubuntu.com/changelogs/pool/main/l/linux-firmware/linux-firmware_1.79/changelog -- and substituted their file in place of the one from the Debian "firmware-atheros" package (version 0.36). I confirmed that the firmware images are in fact different. Result: the firmware change appears to have no effect at all. I tried booting up with all four combinations of {libmtp-runtime present/not present} x {Debian firmware/Ubuntu firmware} and the Bluetooth device works or not depending on the presence (no) or absence (yes) of libmtp-runtime, regardless of the firmware version. I urge other people to try this experiment. Later comments in the corresponding Ubuntu bug report: https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/714862 -- agree with this result: https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/714862/comments/40 https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/714862/comments/53 https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/714862/comments/55 The changelog for the Ubuntu "linux-firmware" development package lists under version 1.87 the entry "UBUNTU: Remove obsolete ath3k firmware". I do not know what the significance of this comment is. http://packages.ubuntu.com/quantal/linux-firmware http://changelogs.ubuntu.com/changelogs/pool/main/l/linux-firmware/linux-firmware_1.88/changelog -- Ian Bruce -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
