Is this keyboard always connected to the same port? There is no bus 1 port 2 device on your earlier lsusb output, so it was either not connected there or not detected due to malfunction. > journalctl --since 2025-07-01 --grep "reset full-speed USB device > number" >=20 > Jul 24 15:56:34 kernel: usb 1-2: reset full-speed USB device number 14 > using xhci_hcd > Jul 24 15:56:35 kernel: usb 1-2: reset full-speed USB device number 14 > using xhci_hcd > Jul 24 15:56:36 kernel: usb 1-2: reset full-speed USB device number 14 > using xhci_hcd > Jul 24 15:56:37 kernel: usb 1-2: reset full-speed USB device number 14 > using xhci_hcd > Jul 31 19:53:02 kernel: usb 1-2: reset full-speed USB device number 50 > using xhci_hcd > Jul 31 19:53:03 kernel: usb 1-2: reset full-speed USB device number 50 > using xhci_hcd > Jul 31 19:53:04 kernel: usb 1-2: reset full-speed USB device number 50 > using xhci_hcd > Jul 31 19:53:04 kernel: usb 1-2: reset full-speed USB device number 50 > using xhci_hcd > Aug 06 16:51:34 kernel: usb 1-2: reset full-speed USB device number 12 > using xhci_hcd > Aug 06 16:51:35 kernel: usb 1-2: reset full-speed USB device number 12 > using xhci_hcd > Aug 06 16:51:36 kernel: usb 1-2: reset full-speed USB device number 12 > using xhci_hcd > Aug 06 16:51:36 kernel: usb 1-2: reset full-speed USB device number 12 > using xhci_hcd So this port was getting reset in the past. Can you also check: - how many of those resets were followed by "HC died" - if all "HC died" events were caused by resets of port usb 1-2 (or some other port) And for the record, what exactly was the original problem which you reported to Suse and believe to be caused by a kernel upgrade? Was it "HC died" and loss of multiple devices, or just the keyborad failing to work and spamming "reset USB device numebr x", or something else? Regards, Michal
