Logitech M170 mouse some times hard freezing and lag for 5-7 seconds. I'm try to disable power saving for usb devices, but it don't help.

sudo powernap-action --disable usb_autosuspend

and 

echo 2 | sudo tee /sys/bus/usb/devices/*/power/autosuspend >/dev/null

In dmesg always after freez

[ 6591.387398] perf: interrupt took too long (2502 > 2500), lowering kernel.perf_event_max_sample_rate to 79750
[ 9650.687098] perf: interrupt took too long (3283 > 3127), lowering kernel.perf_event_max_sample_rate to 60750
[18608.931249] perf: interrupt took too long (4145 > 4103), lowering kernel.perf_event_max_sample_rate to 48250

Maybe this is not related, but always a similar message.

Laptop: Lenovo-ideapad 320

I'm not sure if it's your USB ports or the USB hub which is trying to auto-suspend due to power management.

What's the output of 

cat /sys/bus/usb/devices/usb*/power/control

what message do you get now and do you still get the same if you run this after booting the machine?

echo "on" | sudo tee /sys/bus/usb/devices/usb*/power/control

If it is not persistent between machine reboots.

You can also check with powertop if you prefer something slightly more user friendly.

sudo apt-get install powertop

Look on the tunables tab. If it's set to bad then auto-suspend is disabled and this is what you want. Try and let us know?

  • is there a tiny button or a hole to do a factory reset on your Logitech M170 wireless mouse and see if it helps? – Shaze Oct 12 '18 at 11:05
  • No, no any buttons. At Windows 10 on same laptop everything ok. On PC under windows mouse work fine. – Maks Oct 12 '18 at 12:47
  • Shame Logitech hasn't added any SW utility for Linux. Only windows :( – Shaze Oct 12 '18 at 14:55
  • If you really want to debug try - grep -i mouse /var/log/dmesg dmesg | grep Logitech:

  • Try to install this and see if it works? sudo apt-get update
    sudo apt-get install solaar     – Shaze Oct 15 '18 at 09:01
  • It looks strange, but when the charging cable is disconnected, the mouse stops freezing. When connect charger it start again. It looks like a hardware problem, may be bad shielded input power filters. I'll try to use a USB hub and watch. OR HDMI connector. When work from battery without HDMI monitor everything good... But on windows work fine on same laptop same charger same monitor... – Maks Oct 16 '18 at 06:08
  • it is definitely strange behaviour, it might be a hardware issue than a software one if you have tried everything. You are also eliminating all the possibilities so it works fine on Windows but not on Ubuntu upon connecting the charging cable? – Shaze Oct 16 '18 at 10:58
