I've been having a similar issue, but it never resolves by itself - I  
have to unplug and re-plug the mouse, although I can use the same  
port.  However, I do not get any of those error messages, just the  
disconnects.

It seems to most commonly occur when switching between X and one of the  
text consoles, but not consistently.  I'm on kernel 4.20.0, but it was  
the same with several 4.19 kernels also.

I wonder if any of the kernel USB parameters might be involved here.
