└─>HP HIL keyboard support (simple driver)
In linux kernel since version 2.6.20 (release Date: 2007-02-04)  
The "Human Interface Loop" is a older, 8-channel USB-like
controller used in several Hewlett Packard models. This driver
was adapted from the one written for m68k/hp300, and implements
support for a keyboard attached to the HIL port, but not for
any other types of HIL input devices like mice or tablets.
However, it has been thoroughly tested and is stable.

If you want full HIL support including support for multiple
keyboards, mice, and tablets, you have to enable the
"HP System Device Controller i8042 Support" in the input/serio
submenu.
