Fnatic RUSH mechanical keyboard ignores keypress

[Andrius V <vezhlys%gmail.com@localhost>]

Hello,

Recently (around a week ago) I faced an issue with my mechanical
keyboard (Fnatic Gear Rush) that it doesn't react to any keypress
anymore (in general I can't use it as a keyboard). Weirdly enough this
issue is present in any NetBSD setup (tested netbsd-9, current and
even older 8.1 setup which definitely worked before). It powers up, it
is visible in dmesg, its USB hub works (mouse connected to it works
without issues), Num/Caps Lock LED light reacts, if I click it on
other attached keyboard, but pressing any button has no effect. Other
non-mechanical "cheap" USB keyboards work without issues. Initially, I
though it may be related to my recent UEFI update but it fails to work
on other systems too. The original system is Ryzen 5 1600 based on
Biostar x370gt5 motherboard. The keyboard itself is definitely fine
and perfectly works on any other operating system I have (Manjaro,
Windows 10), including UEFI/BIOS interface. Any ideas what may be
causing this weird behavior? Thank you.

from dmesg:
uhidev0: Fnatic Gear (0x195d) RUSH Mechanical Keyboard (0x2029), rev
2.00/1.09, addr 8, iclass 3/1
