Then it regre= ssed shortly afterwards. =C2=AF\_(=E3=83=84)_/=C2=AF That's why I said a few months ago that trying to find what broke it is a g= ood start point. Solving it seems like a matter of finding the culprit by narro= wing down the range of changes between a known working point and now. Then it sh= ould be a matter of testing and sending a small patch that builds onto what's already there in less than ten lines, adding one or more missing quirks. If I were to start working on another fix now I would also compare the pack= et flow between the Windows and Linux Bluetooth stacks and see what's up and w= hy it locks up after receiving very trivial stuff. Linux is probably doing something extra. :) Comment #165 here and above (testing getting rid of the event filter thingi= e) seems also like a good candidate to expand the quirk list: https://bugzilla.kernel.org/show_bug.cgi?id=3D60824#c165 Food for thought. --=20 You may reply to this email to add a comment.
