For the past few weeks I've had strange issues with my USB mouse
randomly disconnecting and reconnecting right afterwards. At first I
thought it might be the USB port dying, but it happens with multiple
USB ports (both USB 2 and 3) and two different Logitech mice. I
haven't noticed any issues with other USB devices.
Is this more likely a hardware or a software problem? I'm on kernel
4.14.83 and I'm pretty sure the problems didn't start right after the
update, although it's hard to tell because the disconnects seem
completely random and don't even happen every day. Dmesg output looks
something like this, sometimes with multiple disconnects in a row,
with the device number being incremented each time:

Less often there are also errors like:

Usually the mouse starts working again right away, but sometimes I
need to switch it to another port despite it being visible in lsusb.
This, I guess, has something to do with the device number changing.
One thing I suspected was USB power management, but as far as I know
I haven't enabled any such options, at least not on purpose.

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.
