To preface this, I owned this mouse for over a year now and have used it with no problems on this same hardware with different Linux distros (Fedora, Arch, Manjaro). It was not until I installed Debian 9 that I started having issues.

Firstly, the only way I am able to get the mouse to pair is directly after a reboot, otherwise pairing fails altogether. Then, after pairing or turning the mouse on for the first time, the mouse will connect and the light turns solid for about three seconds then the light on the mouse begins slow blink as if nothing is connected to the mouse. At no point during this process does moving the mouse cause the cursor to move on the screen. Additionally, after connecting the mouse initially, running the info command in the bluetoothctl terminal prints the following output.

The mouse continues to show as Connected: yes even after the mouse disconnects or is powered off entirely. I have tried unpairing and pairing the mouse numerous times under different conditions. I've tried the advice from the following posts:

I am running BlueZ version 5.43-2+deb9u1 on Linux kernel 4.9.0-8-amd64 on a Thinkpad T480. What can I do to solve this?
