..And here it is!
So after a little bit of fiddling and messing around, I finally got the keyboard integrated with a small USB hub giving me 3x internal USB ports. One of those USB ports can be seen at the top giving me the fingerprint reader.
The internal membrane keyboard is now also converted over to USB. So no more PS2 port.
Overall the keyboard provides an amazing typing experience allowing me to quickly type but also feel the keys quite well. It's not a mechanical but it's sure close.
