Well, the idea is just to have an extra, internal usb-port for a usb-drive, mouse dongle or such. The hub chip I'm using is a 4 port hub, and the atmega for the keybord controller uses one port, so we have 3 left. Might as well make hardware support for it, if not used, we can just skip mounting the components for the extra port.

That would actually be pretty cool to have onboard storage in your keyboard.

I have been playing with the idea to try and fit a m.2 ssd in the case, since it's usb 3, you should get decent speeds ;D (not sure if there is enough space tho)

Very cool. Excited to hear more about this.

I've powered the boards now, so far all is good. I have usb 3 functionality and it shows up in the OS like it should, but only tested briefly. Next step is to program the onboard EEPROM that configures the hub, so I can get usb 2.0 functionality (swap the data-lines). Then we can test the hub properly, and program the atmega for the HHKB controller. I'll keep you updated. I'll hopefully have time to continue this weekend. :D

Indeed, pretty cool project :) I hope, there will be an option to buy that controller in future somehow ;)
