Hi, just sharing my feedback. In 2024 I ordered a
Mini-B USB Controller for Pro2 for my HHKB pro2 (KB400B).
If I remember well I received the controller like 2 weeks after my order at my place in France.
Considering it comes from Japan, it was pretty fast!
Some days ago I took the time and I finally installed it into my HHK. Went pretty well.
Installation in the chassis easy, nothing difficult. (Literally unscrew unplug the stock controller, swap it, plug, screw and that's it).
I flashed my custom keymap firmware using
QMK, for ref keyboard is
hhkb/ansi/32u4No issue, works like a charm.
I can only recommend it! This Hasu controller is really a nice piece of hardware
