Converting linux keycodes to X keycodes

[Marvin Raaijmakers]

If the remote control is connected via USB it will not be possible to
set keycodes. At the moment I am trying to modify the input drivers to
make this possible.
If you can set the kernel keycode, then of course you can get the X
keycode by using xev. However you may find it easier to use the
translation table I made:

/* Kernel keycode -> X keycode table */
const unsigned int keycode_table[256] = {
	  0,   9,  10,  11,  12,  13,  14,  15,  16,  17,  18,  19,  20,  21,
22,  23,
	 24,  25,  26,  27,  28,  29,  30,  31,  32,  33,  34,  35,  36,  37,
38,  39,
	 40,  41,  42,  43,  44,  45,  46,  47,  48,  49,  50,  51,  52,  53,
54,  55,
	 56,  57,  58,  59,  60,  61,  62,  63,  64,  65,  66,  67,  68,  69,
70,  71,
	 72,  73,  74,  75,  76,  77,  76,  79,  80,  81,  82,  83,  84,  85,
86,  87,
	 88,  89,  90,  91, 111,  221, 94,  95,  96, 211, 128, 127, 129, 208,
131, 126,
	108, 109, 112, 111, 113, 181,  97,  98,  99, 100, 102, 103, 104, 105,
106, 107,
	239, 160, 174, 176, 222, 157, 123, 110, 139, 134, 209, 210, 133, 115,
116, 117,
	232, 133, 134, 135, 140, 248, 191, 192, 122, 188, 245, 158, 161, 193,
223, 227,
	198, 199, 200, 147, 159, 151, 178, 201, 146, 203, 166, 236, 230, 235,
234, 233,
	163, 204, 253, 153, 162, 144, 164, 177, 152, 190, 208, 129, 130, 231,
209, 210,
	136, 220, 143, 246, 251, 137, 138, 182, 183, 184,  93, 184, 247, 132,
170, 219,
	249, 205, 207, 149, 150, 154, 155, 167, 168, 169, 171, 172, 173, 165,
175, 179,
	180,   0, 185, 186, 187, 118, 119, 120, 121, 229, 194, 195, 196, 197,
148, 202,
	101, 212, 237, 214, 215, 216, 217, 218, 228, 142, 213, 240, 241, 242,
243, 244,
	  0,   0,   0,   0,   0,   0,   0,   0,   0,   0,   0,   0,   0,   0,
0,   0
};

I made this table for my project keyTouch (http://keytouch.sf.net). If
it is possible to the set keycodes for your remote control, then you can
even use this program to bind actions to it. KeyTouch assigns kernel
keycodes to scancodes, translates the kernel keycode to a X keycode and
executes an action when that keycode is pressed under X. By using the
keyTouch editor program you can make a so called keyboard file for your
remote control and import this keyboard file in keyTouch to get working.
