[Patch] usb/hid:Microsoft Natural Ergonomic Keyboard 4000 Driver 0.3.2

From: raise.sail
Date: Fri Sep 29 2006 - 00:52:53 EST


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.
