Public bug reported: This is similar to https://bugs.launchpad.net/bugs/1829737 - however the issue was not fixed by linux-firmware 1.173.8 so I was advised to log a new bug.
I have an ASUS ZenBook 14 - UX433FA - which based on this - https://www.notebookcheck.net/ASUS-ZenBook-14-UX433FA-Core-i5-8265U-SSD-FHD-Laptop-Review.403541.0.html - I believe has an Intel 9560 chipset (I am not sure how to independently verify this). With kernels older than 4.20 I can successfully pair my bluetooth mouse (Logitech MX Master) - but with newer kernels I get "Bluetooth: hci0: request failed to create LE connection: status 0x0c" messages. I'm running Linux Mint 19.1 I tried installing linux-firmware 1.173.8, and it didn't seem to help - I also downloaded 1.173.9 proposed from here: https://launchpad.net/ubuntu/bionic/amd64/linux-firmware/1.173.9 and that also didn't seem to help. Both after a cold reboot and a warm reboot I see [ 14.724438] Bluetooth: hci0: Firmware revision 0.1 build 201 week 49 2017 in my dmesg output. Bluetooth works just fine with earlier kernels (however other aspects of the laptop like suspend don't work as well, which is why I'm trying the newer kernel.
