Description:
I am using a ArchLinux distribution. `uname -a` gives me:

Linux torre 5.4.87-1-lts #1 SMP Wed, 06 Jan 2021 14:56:05 +0000 x86_64
GNU/Linux

So, some months ago, my USB Keyboard stopped being detected at
boot. I mean, eventually got detected, after the 9 seconds timeout and
this is a bit frustrating, since, 1. it is a keyboard, meaning that it
should not have any problem, and 2. I start typing immediately, only to
find how that my keystrokes are getting lost.

This did not happen when I started using ArchLinux, 2 years from now.
Also this did not happen like 5 months from now, imprecisely calculated.

Today, I took the time to look at the journal and this is what it has
to say about my issue:

Hope someone can make my keyboard detect as soon as my Linux is booted.
