/*
|
||||
You can play with this if you are
|
||||
interested in USB. I'm not planning
|
||||
on doing USB unless the legacy PS2
|
||||
keyboard/mouse mode disappears.
|
||||
There EHCI UHCI in various ICH chips and
|
||||
others and God knows how many custom packet
|
||||
formats for different keyboards and mice. Okay,
|
||||
I suppose if BIOS can make a universal
|
||||
packet, it is done just one way for
|
||||
different mice. PS2 is more compatible.
