Hi Christopher, Thanks for your reply, and trying to "enlight" me . I read the link you give, but still I don't see the logic. Say that I'd have some time to look further in this bug, and trying different things. It is very difficult for me then to find reports with bug similar to mine. I see no relevant metadata in launchpad.
For instance: - https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1351882 This one is very similar, same laptop, same hardware but strangely the USB device id are slightly different (IMC networks). So not 100% duplicate, but clearly very related. We don't see this in launchpad. - https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1349752 Similar bug, similar hardware but different vendor. Maybe same bug. Maybe not duplicate, but clearly related. In any case, we don't see that in launchpad. - https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1277528 The report alperyilmaz. There was an interesting comment from Max Schwarz (xqms), and a possible user space fix. Since it is a different report, I did not see it. In the meantime, the bug is flagged as "expired", so it does not even appear if you do a basic launchpad search. Also, why not announce here people created a new bug report? I personally would like to know it, so that at least I have a chance to register myself to them. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1260825 Title: 168c:0032 ath3k built-in bluetooth cannot load firmware - sporadic Status in “linux” package in Ubuntu: Triaged Bug description: This is on an ASUS N550JV.
