I'm using Ubuntu 18.04 for a long time and I never had issues of freezing until recently from past month I'm facing this issue. But before pointing finger at Ubuntu, I want to make sure which is the actual problem.

These are the things I have tried so far. 1. I saw in a post that, the reason for mouse and/or keyboard getting froze could be lot of dust in the USB ports. So I have cleaned my CPU for 2 times. 1st time I really had dust particles which could create a thick web roll kind of thing. Second time I used vacuum cleaner exhaust to throw away all the dust particles in any corner of SMPS and Proccessor. I also cleaned USB ports with high pressure air.

  1. I removed mouse and keyboard and tried reconnecting, still it's not getting detected.

While observing I found out that, I clicked on a link of stack overflow, while my mouse and keyboard froze, the website still loaded without freezing after about 5 seconds. So this concluded that it's not whole OS only USB devices.

I still think this could be the fault of Ubuntu because, both mouse and keyboard can't magically get issue at the same time. Both will work well for some time after hard system reset. So I was looking at system logs. Below are the messages, which I don't understand what went wrong.

    Please add the output of sudo lshw -C display and apt policy xserver-xorg-input-* and tail -n 999 /var/log/dpkg.log | grep "status installed" – Raffa Apr 06 '20 at 18:41
  • @Raffa, I've updated the question with the output of the commands you have provided. – learner Apr 07 '20 at 14:58
  • I see you upgraded to a new kernel today. Is there any improvement with the new kernel? If not, please try booting to an older kernel. One that was installed before this issue happened and see if the issue is present. If present then probably it is a hardware issue either mouse/keyboard, USB port or controller. To narrow this, disconnect USB/HDMI hardware and cables and reconnect them one by one as well as connecting to different ports until you find the faulty one. There is also a chance that video drivers are to blame so please run sudo lshw -C display and post the output. – Raffa Apr 07 '20 at 20:24
  • 1
    You ran the command incomplete like so sudo lshw -C while it should be sudo lshw -C display. As for the message reset low-speed USB .... This means the device gets disconnected ( that's why mouse and keyboard stop working ) for any of the reasons mentioned in my comment above. As for the system itself, it is ok and not freezing as you noted. So in short it is ether new kernel has no good support for mouse/keyboard or it is actually a hardware problem. Waiting for your update. – Raffa Apr 07 '20 at 20:30
  • @Raffa, There were 2 Kernels, 4.15.0-91 and 4.15.0-96. I selected the old one (91) from Grub menu. Still the problem exists. I've updated the "lshw" output. About diagnosing USB ports, I didn't get whether you are asking me to remove the devices from outside the CPU or you are asking me to diagnose by removing the cables attached to Mother board. But one other observation I already have done is, when the mouse completely freezes, I have tried reconnecting them to other USB ports, but it will not work until next system restart. – learner Apr 08 '20 at 18:24
  • I meant to disconnect the USB/HDMI cables from the ports outside the machine. Limit the connected devices ( speakers, microphone, headphones, monitors, USB drives, mouse/keyboard .... etc ) and preferably try changing mouse and keyboard with different ones if you have spare ones. low-speed USB device usually means a mouse or a keyboard and reset low-speed USB device means there is faulty electrical signal due to probably faulty USB and sometimes HDMI cable or device. – Raffa Apr 08 '20 at 18:35
  • Your display card Intel integrated rarely has issues with drivers as it has good enough support in Ubuntu and the correct driver i915 is in use. So I suggest you rule out VGA driver related issues. – Raffa Apr 08 '20 at 18:44
  • @Raffa, I've not much bothered about drivers until now in Ubuntu. Not having graphic card could be another reason for not exploring much on drivers. "faulty electrical signal", this sounds like the system logs I've seen using "Logs" app -> important -> system -> "usb 2-1-port4: over-current condition". The same shows for rest of the 3 ports. Regarding ruling out VGA driver issues, is there is any command I can start with? – learner Apr 09 '20 at 03:09
  • 1
    Actually what I meant by ruling out VGA driver issues is there is no need to worry about it as it seems not to be the cause in your case. So it appears to be either faulty mouse and/or keyboard which is common and it is simply solved by changing them or a faulty USB controller on the motherboard which is not common but requires changing the motherboard. – Raffa Apr 09 '20 at 03:18
  • 1
    Requires changing motherboard? That sounds scary @Raffa. Even it's tough to get out of home in this pandemic situation. Anyway thank you for helping me out for diagnosing the issue. I'll try to find out whether it's just mouse or the motherboard which have the problem. If you can post this as answer I can accept that. Thank you again. – learner Apr 09 '20 at 14:51

This:

kernel: [37450.521244] usb 1-1.4: reset low-speed USB device number 31 using ehci-pci
kernel: [37452.337312] usb 1-1.4: reset low-speed USB device number 31 using ehci-pci
kernel: [37456.478074] usb 1-1.4: USB disconnect, device number 31

means that a USB device on port number 4 gets disconnected, that's probably why mouse or keyboard stop working. As for the system itself, it looks OK and not freezing as you noted.

The reason for this is either the new kernel has no good support for mouse/keyboard or it is actually a hardware problem.

Please try booting to an older kernel. One that was installed before this issue happened and see if the issue is present. If present then probably it is a hardware issue either mouse/keyboard, USB port or controller.

To narrow this down, limit the connected USB/HDMI devices ( speakers, microphone, headphones, monitors, USB drives, mouse/keyboard .... etc ) and preferably try changing mouse and keyboard with different ones if you have spare ones. Disconnect USB/HDMI hardware and cables and reconnect them one by one as well as connecting to different ports until you find the faulty one and change it with a new one.

Notice:

low-speed USB device usually means a mouse or a keyboard and reset low-speed USB device most likely means there was faulty electrical signal due to probably faulty USB and sometimes HDMI cable or device.

This means it is most likely either faulty mouse and/or keyboard which is common and it is simply solved by changing them or a faulty USB port/controller on the motherboard which is not common but requires changing the motherboard.

  • Any thoughts on "Over current condition" found in the logs, "Logs" app -> important -> system -> "usb 2-1-port4: over-current condition"? If I remember correctly, I'm seeing this log from the day 1 of using 18.04 Ubuntu (Probably from past 1 and half years), But I've never faced mouse issue like this. – learner Apr 10 '20 at 03:42
  • @learner As for "Over current condition" I can't suggest anything. The clear signs are the reset low-speed USB device number 31 and USB disconnect, device number 31 and they both state that the USB device gets reset and disconnected after a while and no more I can suggest than what is in the answer. Best of luck – Raffa Apr 11 '20 at 23:36
  • Thank you. I tried using my mouse in my office's laptop, it got frozen there also. I borrowed a mouse from my cousin. As of now, it's working fine. The only suspicion I had was, is it because of "Over current" problem, my mouse was screwed. That's why I pointed that out. Thank you again. – learner Apr 13 '20 at 03:41
