Changelogs:
1. As Trantorvega suggestion, some key also yield keycode that less than 255. so we can use them under console, etc.
For how use this driver in userspace, you can find much useful information at follow URL:
http://gentoo-wiki.com/HOWTO_Microsoft_Natural_Ergonomic_Keyboard_4000
However, many discusses can be found here:
http://www.ubuntuforums.org/showthread.php?t=229559
Thanks trantorvega here again.
This driver requires:
1. [PATCH] usb: The HID Simple Driver Interface 0.3.2 (core)
2. [PATCH] usb: HID Simple Driver Interface 0.3.1 (Kconfig and Makefile)
Or you also can get all patches in the mail of "[PATCH] usb: The HID Simple Driver Interface 0.3.2 (core)", see its attachment.
PS: Who is the maintainer of the input subsystem today, Should I forward this mail to him/her?
It can be applied on 2.6.18 at least.
