>Install the newly built kernel, then reboot with it. If it still have the same issue,< Sorry. Much to complicated for me. I'm not a linux expert and this computer is my only working computer. Every modification which could probably lock me out of my system is a worst case scenario.
I compared kernel dmesg from 5.0 and 5.4 and there are errors in 5.4 with the HID driver which are not in 5.0. e.g. [ 2.908901] hid-generic 0003:046D:C52B.0001: input,hidraw0: USB HID v1.11 Keyboard [Logitech USB Receiver] on usb-0000:00:14.0-4/input0 [ 2.909003] hid-generic 0003:046D:C52B.0002: unknown main item tag 0x0 [ 2.909016] hid-generic 0003:046D:C52B.0002: unknown main item tag 0x0 [ 2.909019] hid-generic 0003:046D:C52B.0002: unknown main item tag 0x0 [ 2.909023] hid-generic 0003:046D:C52B.0002: unknown main item tag 0x0 [ 2.909030] hid-generic 0003:046D:C52B.0002: unexpected long global item [ 2.909038] hid-generic: probe of 0003:046D:C52B.0002 failed with error -22 [ 2.909196] hid-generic 0003:046D:C52B.0003: hiddev0,hidraw1: USB HID v1.11 Device [Logitech USB Receiver] on usb-0000:00:14.0-4/input2 ** Attachment added: "dmesg for 5.0" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1863455/+attachment/5418787/+files/d.5.0.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1863455 Title: USB system (mouse and keybord) are not working since kernel update to 5.3.0-26 and 5.3.0-28 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1863455/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
