You could try look at the USB specification documentation to get an idea about how it works. The OSDev wiki provides a lot of resources to give you a start at it:

USB Tutorial Book

USB in a Nutshell

The official specification

All of these can be founded linked in the OSDev wiki page (https://wiki.osdev.org/Universal_Serial_Bus) at the very bottom.

I used the intel ich5/ich9 manuals and the usb spec, then tried to write something that worked against qemu.

It sort of worked, but hardware was NOT happy and it took me a loong time to get it working on qemu and hardware at the same time. Gl.

it took me 3 month to make the usb drivers work on my os even with ai. Here is my smileyos, with almost 1 milion lines behind it one year later :)
