I'm now running fedora 31 on my system at home and at work. On both systems I occasionally notice all my xinput settings have reverted to default, as if I unplugged my mouse and plugged it back in (even though I didn't unplug it). Has anyone else noticed USB weirdness like this? Looking at dmesg, that seems to be what the kernel thinks happened: [ 36.142138] 8021q: 802.1Q VLAN Support v1.8 [ 36.188272] IPv6: ADDRCONF(NETDEV_CHANGE): wlp0s29u1u2: link becomes ready [28350.784597] usb 2-1-port5: disabled by hub (EMI?), re-enabling...

I have no idea what an EMI is, but that's what starts everything.
Hi Tom, Probably not what you asked, but when does that stop me? Is this a "add on" USB card? I have the worst luck with add on USB cards in both Windows and Linux. My shop computer has an add on USB 3.1 card that is a one shot card: I can read a flash drive from it once. After I eject the flash drive, I have to reboot to get it to work again. And this was the forth card I tested. The first three just corrupted the data or blew out. Never have any issue with the USB ports on the motherboard. Are the malfunction port(s) on your motherboard? -T _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
