If it were a kernel issue, then everyone that has a comparable dongle and upgrades their kernel frequently should also see the problem. I normally do a dnf update Sunday morning followed by a reboot, so if I understand your process correctly, it is similar. Things that might be different: my dongle is old (10+ years), plugged into a USB3 port, and it is the only USB device plugged into the system. FWIW, the prior system the dongle and keyboard were used with was an Intel NUC and it also never had an issue with kernel upgrades losing the keyboard. My gut reaction is that this is something specific to your environment. Either USB bus power, or something else happening with the bus between GRUB and kernel. If you haven't already, things you could try: - boot single-user; does problem occur? - boot live media; does problem occur? - anything in the log(s)? - any settings in BIOS? BIOS upgrade? - different USB port - maybe a debug kernel would provide more info? - temporarily move dongle to a different system - move dongle to a *powered* USB hub with nothing else plugged into it. If the problem persists, plug the hub into a different USB port on the system. [when moving to a different USB port on the system, if at all possible move to one on a different internal hub] _______________________________________________ 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 Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
