Keyboard/mouse don't always wake up after suspend

Greetings,

I'm using sddm and kf5, and sometimes, when the laptop wakes up from a suspend, everything wakes up but the keyboard, touchpad, and any other input device I may have plugged on USB ports.

I've checked these pages:
https://wiki.archlinux.org/index.php/Power_management
https://wiki.archlinux.org/index.php/Po … _hibernate

And I haven't found anything that match the symptoms. Although there's something about udev and autosuspend... is it possible my touchpad and keyboards are being treated as USB devices ? Plus, it seems like autosuspend isn't enabled by default, and since I haven't configured it myself, would this really apply for me (https://wiki.archlinux.org/index.php/Po … utosuspend) ?
And if that's not it, what else could be happening ?

EDIT:
For the record, I just noticed that I can "overcome" that problem by going back in suspend mode, and waking up the laptop again. It doesn't always fix the problem: sometimes you end up with the keyboard enabled, but not the touchpad. So, basically, the problem is that keyboard and touchpad aren't always waking up when going out of suspend.

Try adding the "atkbd.reset" kernel parameter to the Grub/Syslinux boot command line.
