Title:
Freeze when usb-data-collision with usb-mouse
Status in linux package in Ubuntu:
Incomplete
Bug description:
To my computer I have connected a USB-hub and to that I have attached
a USB-mouse and a USB-to-Ehternet adapter. The computer sometimes
freezes completely and power button is the only escape. This happens
when I scroll the mouse, press a button or moves the mouse (any event
from the mouse).
This can happen in any running program: Firefox, pdf-viewer,
Libreoffice Writer...
Most often this comes with my usb-to-ethernet LEDs switch off (during
blink), but not always.
Seems to be a collision event between my USB-mouse and USB-to-ethernet
adapter, i.e mutex. An other computer without the USB-to-ethernet
adapter never freezes. Configured in the same way.
(I used Ubuntu 14.04 for a long time and this freeze never happened.
In 18.04 this happens at least every two weeks. It is the same
hardware.)
