Solution 1

It's PowerNap that's doing this.

You can disable just this part of PowerNap's power savings scripts with:

sudo powernap-action --disable usb_autosuspend

Solution 2

Just copy paste the following command in terminal and it will disable auto suspending.

Disabling auto suspending USB

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

Disable USB autosuspend

echo on | sudo tee /sys/bus/usb/devices/*/power/level >/dev/null

Solution 3

Could it be that laptop mode tools are causing this? If so, try the following:

Optional: Create a backup of /etc/laptop-mode/conf.d/usb-autosuspend.conf by copying it in your home folder:
```
cp /etc/laptop-mode/conf.d/usb-autosuspend.conf ~/usb.autosuspend.old
```
Get the USB ID of your mouse/keyboard
```
lsusb
```
This will return a list including ID xxxx:xxxx for your mouse/keyboard.

Edit the original usb-autosuspend.conf

sudo gedit /etc/laptop-mode/conf.d/usb-autosuspend.conf

There will be an entry called AUTOSUSPEND_USBID_BLACKLIST='' change this to AUTOSUSPEND_USBID_BLACKLIST='xxxx:xxxx'
This should stop your USB mouse/keyboard from being suspended. Now you either need to restart your computer or restart laptop-mode using
```
sudo service laptop-mode restart
```

I don't know how , but somehow automatic power-off of usb devices got accidentally enabled. Now my usb mouse goes off even if it's idle for 2-3 seconds. It's really irritating.

This happened after I installed powertop and powernap. Maybe it has something to do with these two applications.

How can I disable this "feature"?

Disable USB autosuspend is exactly what I was looking for. Here I don't have powernap installed.

Same, I don't have powernap either. This worked for me.

Is that reboot-persistent ?

You find your ID with the command lsusb|grep -i mouse|sed 's/^.* ID //g'|sed 's/ .*$//g' (assuming there is the word "mouse" in the string for your mouse) If you don't find out the ID of your mouse, use watch -d lsusb while you plug in your mouse.

What is this difference between the two scripts? Do I need both or only one of them?

I would recommend the use of tlp. @rosencreuz

At least in Ubuntu 15.04, this file has been moved to runtime-pm.conf and the line to add the id to is now called AUTOSUSPEND_RUNTIME_DEVID_BLACKLIST="". Strangely, I couldn't get my blacklist to work so I just disabled this module by setting CONTROL_RUNTIME_AUTOSUSPEND=0. It worked!

I had to change line 2 to do sudo sh -c "echo on > $foo";

It worked on Debian Jessie (8.4), but file is /etc/laptop-mode/conf.d/runtime-pm.conf

Works, but converting from device number given by lsusb, and number in /sys/bus/usb/devices, is hard. I see no relationship. The bus number is the same, then I just poke around looking for a matching manufacturer:device ID.

For me in debian jessie (8.4) it was laptop mode. See answer below. Writing to /sys/bus/usb/devices/«device»/power/level also worked, see other answer.

You were spot on, in my case I ran "lmt-config-gui" for Laptop Mode Tools and unchecked "Enable module runtime-pm". This issue began after updating my KDE Neon kernel from 4.4 to 4.8 last night and was driving me bonkers! Thanks!

We need to run both commands. It works !!

On Ubuntu 16.04 kern.log says: WARNING! power/level is deprecated; use power/control instead

I didn't have laptop-mode installed (though something was suspending my USB) and when I did install laptop-mode-tools I didn't have the usb-autosuspend.conf (that was for 14.04 but I have 16.04). I did have a /etc/laptop-mode/conf.d/runtime-pm.conf per askubuntu.com/a/370406/318507 . Still waiting to see if this fixes the issue or if I have to track down what was originally suspending it.
