How do I get a wireless logitech unifying USB keyboard to wake Ubuntu from suspend?

Question :

I would like to use a shortcut or any key to wake my computer from sleep mode using a Logitech wireless unifying keyboard (K800). I've already tried solutions from here and there.

Best case scenario, I would like the computer to wake only on keyboard events and not when the mouse linked to the same unifying device moves. But I'll take any valid solution that allows me to wake the laptop with one single shortcut or any key.

Best case scenario again, I would like to find a simple solution (not like this one)

Edit :

I just figured out that I can't even wake it with it's own internal keyboard (don't know if I messed up with some configuration trying to set up a workaround, or if it's always been the case.) So currently, only power button can wake that sleepy lazy laptop.
I've been through the same issue with all Ubuntu versions since 15.10, and still now on 17.04.

Solutions tried :

The solaar workaround answer on How do I get a wireless USB keyboard to to wake Ubuntu 13.10 from suspend? doesn't work.
That command have no impact on disable/enable status:

sudo echo USB1 > /proc/acpi/wakeup
I've unsuccessfully tried to create wakeup files in, for instance (not sure to know where to put them):

sudo echo enabled > /sys/bus/usb/devices/1-3.3/power/wakeup
I've unsuccessfully tried to add this in /etc/udev/rules.d/90-keyboardwakeup.rules

SUBSYSTEM=="usb", ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c52b" RUN+="/bin/sh -c 'echo enabled > /sys$env{DEVPATH}/../power/wakeup'"

Try the wakeup events like in this post into your BIOS! enter image description here

But I'll take any valid solution that allows me to wake the computer, with one single shortcut, or any key.

A non-logitech wireless keyboard or mouse should work. I had the same problem with Ubuntu Mate 16.04LTS on a Gibabyte MiniPC with Logitech devices.

But i can wake with wireless devices that are non-Logitech, non-unifying receiver like Nulaxy ML11 2.4GHz Wireless Mouse (confirmed working out of the box can wake Ubuntu) or for a keyboard the Azio Vision Backlit Wireless Keyboard (KB506W) Updated Version (haven't confirmed can wake) or this LotFancy 2.4G Wireless Mini Backlit Keyboard Mouse Touchpad Combo (confirmed working out of the box can wake Ubuntu)
