I'm so glad to hear there are other PS/2 keyboard proponents.

USB kinda, sorta works but the bus nature of it, and having
more than two devices connected, it means there's intermittent
bus resets and ports disabled by kernel until reboot if it's
those kind of days.

Is it still native when connected with a USB-to-PS/2 adapter?

I'm asking because it's very limiting when you shop around
for a keyboard with a "pure" PS/2 connector. It's already hard
to find an ergonomic keyboard that has mechanical switches,
and insisting on non-USB shrinks the list, leaving not much
of a selection.

What was wrong with 4.15.5? I missed the news.
