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.

Hi Benoit ;),

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)

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.

Won't work for USB keyboards.

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)

What version of showkey are you using?

showkey: (console-tools) 0.2.3
(maybe modified by debian: console-tools_0.2.3dbs-52)

Actually while working with the Input Event system for my mouse under Xfree (started by hacking moudev to support eigth button mouse and remove the 'double' press on my Forward button (one press from the Logitech Cruise mode, and another from the conversion in mousedev (and not accurate), and after that creating an Input Event mouse driver for XFree) i found another weird thing (not investigated for now): All 'extra' keys of the Keyboard (the standard one: play/pause/mail/... and the new which doesn't work) generate events on the same device than the mouse (but the normal keys goes to another event device).

Ah - maybe you want to try with a showkey from kbd-1.12 or so. I think console-tools-0.2.3 is from Oct 1999 and kbd-1.12 is from Jan 2004. In case you still have problems I'd like to hear. Write to [email protected].

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

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.

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.
