Questions about the USB HID device drivers

[Apollo D. Sharpe, Sr.]

Hello,

Specifically, I'm interested in how the USB keyboard & mouse drivers 
publish their nodes. I've been combing through the sources of both 
drivers in an attempt to understand a) how they make available the data 
from their devices, b) how they publish their device nodes, and c) where 
all of the code that implements both sets of sequences is stored at in 
the source tree. I currently see the ukb & ums driver sources. Beyond 
that, I'm not sure where to look in order to follow the path between 
those drivers & /dev. Can anyone help me understand this?
