Logitech M590 mouse and Linux 6.11.4

Due to the recent upgrade of Linux kernel to 6.11.4, my bluetooth mouse (Logitech M590) cannot connect. I tried many times, and sometimes I can connect, but most of the time it fails. There were several related posts: here and here.

Since my storage doesn’t have enough space to install Linux LTS, I can only wait for the fix from Linux. While waiting for the fix, I remembered that M590 allows to use a USB receiver. As a result, I installed ltunify package and now it works. The only drawback is that one of my USB ports is occupied.

Besides that, I have a bluetooth controller (gamepad, joystick), but it doesn’t auto-connect since the update of 6.11.4. I have to manual connect the device through bluetooth manager.
