The new "New" Model M Keyboard does afaik. My ten-key-less (space saver) (anno 2019 or so) has an older MCU which apparently doesn't get the USB protocol quite right. Every now and then (perhaps once a week) the keyboard isn't recognized at boot (currently Windows 10, but it's the same in Linux). I have it connected to a switchable USB hub, so that's not a big deal. More annoying is, that rarely (about once a month) the 'Q' key is dead (real fun when a password contains it). Most annoying is that the 'T' key tends to bounce (that developed only after two or three years of use, so probably not firmware related). Overall, I'm still satisfied, but can't wholeheartedly recommend it.
Unicomp offers (or offered?) to repair those older "New" Model M (replace the MCU), but I moved internationally meanwhile, so this probably not an option anymore. I wished, they would offer the MCU daughterboard separately, so that I could install it myself.
