[SeaBIOS] Extending SeaBIOS for additional USB-HID devices

[Fox, Ethan]

Hello!

I am a university student and I am interested in extending SeaBIOS for a project which involves requiring connecting a USB SoloKey to your computer during the boot process. Implementing this in SeaBIOS seems promising since it looks like SeaBIOS has code written to interface with USB-HID keyboard and mice. I believe that SoloKey also follows this USB-HID spec. Is it feasible to extend the USB-HID code to also interact with SoloKey, or am I going to run into some road blocks? Any advice is welcome.

Thanks, Ethan Fox
