The USB mouse ceases to work after a while (reboots fix it sometimes but (1) sometimes not and (2) to reboot frequently is not what I want). After checking /var/log/Xorg.0.log I see the following sequence of messages apparently containing an error (EE) message:

[ 82489.053] (II) config/udev: Adding input device A4Tech USB Mouse (/dev/input/mouse1)

No reliable cure found so far, even though some guesswork (e. g. removing laptop power management tools) keeps going. Any suggestions?

Ubuntu 18.04.1 LTS / Dell Latitude 3440 / A4Tech N60-F

UPDATE: re-plugging into a different USB does not work, of course. Problem was persistent under 16.04 too.

UPDATE2: sudo rmmod usbhid + sudo modprobe usbhid does not help.

UPDATE3:

UPDATE4: after trying sudo modprobe -r psmouse the mouse is alive again (not immediately, I had to wait for no less than 30 seconds) but the touchpad is dead. Looking now for a way to resurrect the touchpad. The output of grep -i mouse /var/log/Xorg.0.log (the tail of it) is now as follows:

  • Try the first section of this answer: https://askubuntu.com/a/1064744/307523 – WinEunuuchs2Unix Aug 16 '18 at 10:35
  • The first section (the 'new script' starting with for i in /sys/bus/pci/drivers/[uoex]hci_hcd/*:*; do) effectively killed all USB devices. Maybe, the second (a longer script, starting with ZeroBUS=$(lsusb | grep 045e:0745 | cut -c 5-7 )) should work? – Alexei Kouprianov Aug 16 '18 at 10:49
  • The second script needs work because it is powering off the top level USB chain it makes impossible to power them back on until reboot. – WinEunuuchs2Unix Aug 16 '18 at 10:50
  • Well, but the first script does not work either. I mean it switches all USB devices off, but the mouse stands still as it was. – Alexei Kouprianov Aug 16 '18 at 10:53
  • On my machine the second script freezes the mouse, but the first script does not. Something different on your platform for sure. Hopefully someone has a specific answer. – WinEunuuchs2Unix Aug 16 '18 at 10:59
  • It seems to think this is a 2nd mouse. What does grep -i mouse /var/log/Xorg.0.log show? – waltinator Aug 16 '18 at 13:52

Try in Terminal : sudo modprobe -r psmouse

  • Wow. (1) This killed the touchpad (it no longer responds to anything including Fn+F3 which is dedicated to switch it on/off). (2) Not immediately (I think, about half-minute passed) this cured the mouse. Is there a way to bring the touchpad back? – Alexei Kouprianov Aug 18 '18 at 06:44

Open a terminal window and try the following command to re-activate the touchpad: 

sudo modprobe psmouse
