Wakeup from suspend using USB devices (wireless keyboard, Infrared remote)

Hi community,

I want to wake up my computer from S3 sleep using USB devices. I have the Logitech Unifying Receiver plugged into a USB port and a keyboard and a mouse paired to it. By default, my Manjaro doesn’t wake from suspend when I press anything on the wireless keyboard. The power button on the computer works though.

# grep . /sys/bus/usb/devices/*/power/wakeup # <-------- This is by default.

# echo enabled > /sys/bus/usb/devices/usb2/power/wakeup # <-------- Then I enable waking on USB2...

# grep . /sys/bus/usb/devices/*/power/wakeup # <------- ... which gives this.

Now, if I systemctl suspend, the system goes to sleep and wakes up immediately !

I checked if the keyboard is not sending stuff continuously (like broken key) with xev, and it is not. No keypress -> no xev event.

Then I looked at the output of dmesg dmesg or journalctl -e (which includes dmesg). No reason whatsoever given for the wakeup !

Then I looked up some Ubuntu forums suggesting to unload xhci_hcd module. But I can’t possibly do that. I want to use my USB’s as USB 3.0, it’s against the purpose. And even more than that, trying to removing it gives this:

# rmmod xhci_hcd
rmmod: ERROR: Module xhci_hcd is in use by: xhci_pci

I removed then xhci_pci which resulted in me not being able to use my USB keyboard :rofl: so I had to reboot. This is a dead end.

I need a way to wake up from sleep from USB devices.
But before that, I need to know WHY my computer wakes up from suspend immediately after entering in suspend.

Help greatly appreciated !

We will need more information to assist you in resolving your issue.

Please post the input/outputs of all requested commands.

I have tried to help on this issue before. I thought there might be a way to workaround this issue with a systemd service and scripting. Unfortunately there wasn’t any real progress using that method. Perhaps others have ideas on a different approach.

Here is a link with a similar type issue:

See the bottom of this thread, it turns out to be a Gnome extension issue in that case, would not hurt to check it out.

On my computer I needed to go in S1 sleep not S3 to achieve power to USB’s while sleeping.
I had to activate a setting in BIOS that let’s the OS to choose between S1 and S3 (only S3 was available in the default BIOS setting).
Prior to activating that BIOS feature, my /sys/power/mem_sleep had only this:

$ cat /sys/power/mem_sleep
s2idle [deep]

After activating it, I was able to select the shallow default.

$ cat /sys/power/mem_sleep
s2idle [shallow] deep

Shallow corresponds to S1 and is obviously less deep than S3. You can see that by looking at the dmesg output in both cases - S3 turns off more stuff.
Found all I needed to understand this in the kernel documentation.
