[Bug 1531925] Re: Can't connect Logitech Living Room Keyboard [LE]

[Simon Fels]

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.
