From 711a680e35059bc5c7c28d3c4bd0bebd3b7bb6ee Mon Sep 17 00:00:00 2001 From: Bruno Premont Date: Mon, 13 Jul 2009 14:19:58 +0200 Subject: [PATCH] HID: driver for Twinhan USB 6253:0100 remote control Add explicit key mappings for TwinHan USB HID remote control. All dummy Ctrl, Alt, Meta, ... key press/release events generated by the remote are silenced by "unmapping" them. This makes Power and Volume keys single-key and strips the regular (even while idle) key release events for Ctrl, Alt, Meta, ...
