#StackBounty: #16.04 #drivers #bluetooth #firmware Some bluetooth devices not found

Bounty: 50

I just installed Ubuntu 16.04, so far I’ve only had this problem.
Bluetooth is working; in fact, my BT headphones are connected and working properly.
My BT mouse is not found, I just get “searching for devices” all the time. I know it’s compatible with Ubuntu because I tried it at work and no problem.

Weird, right?

I think it has something to do with the firmware, but this is a tad beyond my capabilities. I would appreciate any guidance.
I tried many of the suggestions that pop up in google :(, I updated everything.
Help to a fellow human.

By looking in /var/log I got the following
