Bluetooth adapter disappear after suspend

Hi.
I've some problems with bluetooth mouse. After suspend, the mouse lose connection and the bluetooth pc integrated adapter sometimes disappear. Another times, adapter shows but the mouse not connect. In this case, if I remove mouse device and add it again, the mouse connects.
I have looked for some configuration in energy management but I have not found anything

Some recommendations? Thanks.

Note: With same hardware (laptop and mouse) and Deepin OS, I had no problem

First off test many different kernel versions for improvement.

If that doesn't help then writing a systemd service to refresh your Bluetooth device or the entire USB bus after suspending will probably work for this.

There are many different versions of services on my systemd thread that you could try using. Some may require modifying to your device or bus ID.
