Thank you for taking the time to report this bug and contributing to
Ubuntu.
There would be one way to execute commands without a keyboard: Put the
command into a shell script file, make the file executable, then click
on the file and let it execute. Example script content:
#!/bin/sh
xev | grep -i key | tee /tmp/log
Now about your report. Can you record the kernel timestamp and your
actions to correlate that to your dmesg? CurrentDmesg.txt contains a
bunch of "reset high-speed USB device":
```
$ grep -i usb CurrentDmesg.txt | grep -iv serial | cut -d']' -f2- | uniq -c

"USB disconnect" is what I see in dmesg when I disconnect my mouse. So
this is what I tried to reconstruct:
There are several "reset high-speed USB device" on "usb 1-2". That bus-
port number matches "Logitech, Inc. Webcam C270". The first entry for
"3-2" (your keyboard) is "USB disconnect". So there seems to be no prior
events for it.
I see three explanations for it:
1. The keyboard is having a hardware issue. In that case I would expect
that the frequency of this issue rises until it stops completely.
2. The webcam causes issues on the USB controller which resulted in the
keyboard stop working.
3. A software issue.
My gut feeling is that it is more likely 1 or 2. I suggest to further
monitor and report back. Some questions to answer then: Do you see
failures even without the webcam connected (i.e. no "reset high-speed
USB device" in dmesg)? Can you reproduce the keyboard issue when using
the keyboard on other devices? Did you do something specific application
wise (i.e. do you see a pattern when this happens)?
** Changed in: xserver-xorg-input-libinput (Ubuntu)
Status: New => Incomplete
** Summary changed:
- USB Keyboard sporadically stops working on Ubuntu 24
+ USB Keyboard sporadically stops working on Ubuntu 24.04
** Description changed:
- My USB Keyboard sporadically stops working on Ubuntu 24.
+ My USB Keyboard sporadically stops working on Ubuntu 24.04.
- I used the same USB keyboard with Ubuntu 22, without any issues, except
- occasionally on startup, and unplugging the keyboard and plugging it
- back in would fix it.
+ I used the same USB keyboard with Ubuntu 22.04, without any issues,
+ except occasionally on startup, and unplugging the keyboard and plugging
+ it back in would fix it.
- That didn't fix the issue the 2 times it occurred on Ubuntu 24, both of
- which happened when I was in the middle of something.
+ That didn't fix the issue the 2 times it occurred on Ubuntu 24.04, both
+ of which happened when I was in the middle of something.
Keyboard functionality seemed to return on its own after a few minutes,
although I'm not sure if it was a result of any actions I took.
I pasted
xev | grep -i key
the first time it happened, and
sudo udevadm control --reload && sudo udevadm trigger
the second time it happened, just now, in my terminal, and the issue
seemed to go away after that.
Of course, since my keyboard wasn't functional, I wasn't actually able
to use the ENTER key to run the command in the second case.
I don't remember how or if I actually executed the command in the first
place without a functioning keyboard.
