I went again through the logs and came across the following: [ 1044.196326] Bluetooth: SMP security requested but not available
which is then followed by a lot messages like: Jan 20 08:53:28 samsung930X3G bluetoothd[3988]: Report Map read failed: Attribute requires authentication before read/write Jan 20 08:53:28 samsung930X3G bluetoothd[3988]: Error reading Report value: Attribute requires authentication before read/write What this basically means is that the security checks inside the kernel stack failed and we couldn't build a secured and trusted connection which then in the end means the mouse wont connect properly and fails to work. There is already an upstream bug about this problem at https://bugzilla.kernel.org/show_bug.cgi?id=104011 sadly without an solution other than reverting the change on the kernel side introduced this problem. @Pat: You're seeing this with your MX4 right? I will build a kernel then for it which has the suggested kernel side change reverted just to see if that helps us in this particular situation. ** Bug watch added: Linux Kernel Bug Tracker #104011 http://bugzilla.kernel.org/show_bug.cgi?id=104011 ** Tags added: bluez-touch ** Tags added: bluez-classic -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1531925 Title: Can't connect Logitech Living Room Keyboard [LE] To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1531925/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
