From 1fe8736da695c2b14961438c73d5600538bd92d9 Mon Sep 17 00:00:00 2001 From: Jiri Kosina Date: Thu, 9 Aug 2007 13:24:11 +0200 Subject: [PATCH] HID: add support for Microsoft Natural Ergonomic Keyboard 4000 This keyboard emits a few usages that are not handled properly by hid-input. The usages from MSVENDOR page are colliding with Chicony Tactical Pad device, so we have to distinguish in runtime. Ugly ... Also, the buttons 1-5 have to be handled in a non-standard way, as they are emitted by the keyboard in a bitfield-like fashion, but the field is not presented as bit-field by the keyboard. The keys can't be pressed simultaneously, so the handling we have is correct. This patch also extends hid_keyboard[] with KPLeftParenthesis and KPRightParenthesis as defined by Keyboard page in HUT 1.12. The corresponding usages are also emitted by this keyboard.
