Prominently not here, but present below, is usbcore.
However, didn't you say that even your normal keyboard
and PS/2 mouse don't work? I also don't see any file
systems, nor any disc drivers.

You are leaving out many necessary things. I'm no kernel expert,
but how can you hope to boot without any disc drivers or file
systems present?

I think your problem goes much deeper than just a mouse not working.
I'm surprised you aren't panicking with root file system not found.
