I found a "quick" reproducer - it is firefox and moving photo test (https://testufo.com/photo#photo=3Dquebec.jpg&pps=3D960&pursuit=3D0&height= =3D0) Partly it is regression - mouse resets intoduced by commit: [64cc3f12d1c7dd054a215bc1ff9cc2abcfe35832] USB: EHCI: Do not return -EPIPE = when hub is disconnected. with attached patch there are no usb resets and mouse/keyboards are quite usable it this conditions (while firefox test), only backside effect what i= see - it`s some errors in dmesg at devices removing. --=20 You may reply to this email to add a comment.
