Debugging help for rflink problem

I need some help with debugging the rflink problem.
I have raspberry 3b+ with rflink connected to USB. I had previously a raspbian and virtual environment with no problems. Now changed to home assistant os and rflink stops working after about few hours or so.
I can fix the problem by restarting the core, unplug/plug rflink or restarting raspberry, but it broke again after some time.
I can’t get anything useful out of logs? /var/log directory is empty?
rflink debug logs don’t show any errors, it just stops working. ‘lsusb’ shows its connected and when I unplug/plug it there is ‘dmesg’ that it’s disconnected and connected again

logger:
  default: error
  logs:
    rflink: debug
    homeassistant.components.rflink: debug

This might be some hint?
‘dmesg | grep usb’
