I just upgraded to 4.2 and my external mouse no longer works.
When I plug it in it has the usual dom0 prompt and when I accept it my mouse lights up like it is properly connected yet I can’t move my mouse.
If I got to the qubes devices menu and connect my mouse to a qube then the mouse stops lighting up (and obviously does not work).
Is there anything relevant in journalctl -f in dom0?
Not really that I can see. This is at the very end of everything that happens after accepting the mouse
