I tried the Impish version of Ubuntu, both the traditional and mate version. While with the traditional version there are no problems whatsoever in the use of my peripherals unfortunately with MATE the problems continue. First of all, now I do not recognize the mouse while the keyboard is, continue the continuous system blocks of processes related to bluetooth and the related sending of reports. Is there any hope that a stable solution for bluetooth will finally be found?
On Ubuntu MATE 21.10 it may be caused by Blueman - see the issue at

Steps to reproduce:
1. Enable two my personal Bluetooth devices - Logitech M555b Mouse and SVEN bluetooth speaker, make both discoverable
2. Open terminal and launch `hcitool scan`:
```
$ hcitool scan
Scanning ...
A0:E9:DB:20:FF:FF SVEN PS-100BL
00:07:61:FD:FF:FF Logitech Bluetooth Mouse M555b
```
3. From the same terminal execute `blueman-manager` to get the same devices in GUI, to pair with them
Expected results:
* blueman-manager finds my devices, pair with them
Actual results:
* blueman-manager does not find my devices, shows error in terminal
```
$ blueman-manager
blueman-manager 16.17.35 ERROR Base:85 callback : Unhandled error for org.bluez.Adapter1.StopDiscovery

For my old Logitech M555b Bluetooth Mouse the following method helped:
click on Bluetooth tray indicator
click on Devices
in the opened window uncheck View → Hide unnamed devices
try to find Bluetooth peripheral again by clicking Search button
I have made further tests but the BT system is not working or working badly. Continue to submit crash reports. I tried again with another BT mouse same problems. I have tried again with normal Ubuntu (impish live) and everything works fine, thanks anyway.
