Hi,
I've digged into the kernel source/tools since i do own a new logitech
USB keyboard MX with a great number a keys.
There are two kind of addons keys, some works (scancode in the e0 XX
form): Email, Prev, Next, Play/Pause, Vol+/-, Mute, ...
+ some of thoses generate a simple keycode eg
Vol+: 0x73 | 0xf3 (scancodes: 0xe0 0x30 | 0xe0 0xb0)
+ some doesn't eg:
play: 0x00 0x81 0xa4 | 0x80 0x81 0xa4 (scancodes: 0xe0 0x22 | 0xe0
0xa2)
_ but all thoses key work quite well under X.
The pb come from the new 'Function' keys with replace F1-F12 when the
Flock mod isn't active (it's an hardware mod) and some other (Messenger,
Webcam, iTouch and Buy).
When grabbing with 'showkey -s' nothing appear
When grabbing with 'showkey' i got keycodes like '0x00 0x82 0xd0 | 0x80
0x82 0xd0' (i got same keycodes when pressing mouse buttons except those
are in 0x82 0x90 -> 0x82 0x97 range)
When using the evbug module see that those keys generates > 255
keycodes. (see attached file)
And strangely all thoses keys generates the sames strings than keys with
keycode2 = keycode - 256.
Eg: the 'New' function key (shared with F1) reported by evbug as 336
keycode as the same effect as keycode 80 (keypad 2).
So i'm a little lost :(
And i wanted some direction on how make thoses keys work correctly on
the console (and X eventually. Actually under X some keys generate mouse
button event, some doesn't generate anything).
I am wondering if a good start would not be to extend the kbentry
structure, to use unsigned short at least for the index so whe can acces
a fully 512 entry keymap.

You could make them work using the 'setkeycodes' command to configure
the kernel tables, so you can put some setkeycodes lines in your init
scripts to make those extra keys always avaliable on your console.

Ok thanks for that,
in fact thoses key works under XFree so i doesn't exactly focus on them.
It's the other keys with 0x82 0xXX keycodes, no scancodes (maybe an
empty translation table ? for i've read that USB keyboard need one of
those) and that generate mouse click event under X that are really
bothering me.

What version of showkey are you using?

Won't work for USB keyboards.

I'm sorry, but X only understands the RAW PS/2 protocol, and that one
can only transport keycodes up to 240.
For keycodes above 240, XFree86 would either need to use the MediumRAW
mode, or use event devices for parsing the keyboard.

A normal mode. This is 2.6 extended medium raw mode I suppose.
