Bug#594089: keyboard-configuration: caps lock keycode problem

[Samuel Thibault]

The short story is: Tom's keyboard sends all that when he presses caps
lock:

press: 0x3a 0xe0 0x66
repeat: 0x3a
release: 0xba 0xe0 0xe6

0xe0 0x66 happens to be the "favorites" key on his keyboard with
internet navigation keys.  I thus believe there's a bug in his keyboard
that needs to be filtered at the kernel level.

The long story can be read on http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=594089

Yes, as I said in a previous mail, squeeze Xorg now interprets the
internet scancodes by default, while it wouldn't in lenny and previous,
thus not showing the bug.

Hmm, the question is whether the real "favorites" key send the same
usage and the fake one after caps lock. Any chance Tom could locate
evtest utility and see what MSC_SCAN events being emitted?

Thanks.

Sure. Here's caps-lock:

Could you also post results when pressing the "favorite" and the "prev"
internet keys of your keyboard?

Actually, if these are all the events that evtest reports when pressing
CapsLock then I am confused where the "favorites" ghost press is coming
from... They are not emitted by the device. Do you have a funky keymap
loaded somewhere? Also, was 'showkey -s' issued while in X or in the
text console?

Console. I just ran it now and caps-lock has the same codes as 
"favorites" and right-shift has the same as "previous". So it's not an X 
problem.

It's returning the same codes. Maybe what's going on here is that they 
never worked back in Stable and someone tried to fix those keys, not 
realizing they're the same codes as capslock and right-shift. I'll have 
to test it on my Stable machine tonight to see if those keys work or 
not, tho.

Hmm, it looks like it uses the same usages (MSC_SCAN) for
CapsLock/Favorites and RightShift/Previous... What does lsusb say about
the keyboard (VID/PID)?

Thanks Tom. This device is handled by drivers/hid/hid-lg.c sub-driver
and there seem to be a few issues there, still I do not see how they can
produce the results you are seeing.

First of all, the device appears to use duplicate usages for
CapsLock/Favorites and RightShift/Previous so we better set up the
duplicate usages quirk. I wonder how the other OS copes with diferent
keys using the same usages. Jiri, any ideas?

Also, based on evtest data I only see presses/releases for one key (Caps
Lock, Right Shift, etc.) I do not see the presses for the additional
keys in the evtest stream so I am baffled as to where the additional
scancode is coming from... Do you have some funky keymap loaded?
Anything interesting in dumpkeys?

Also make sure we clear bits when mapping keys to ensure that
hid-input will not try to "add" more keycodes.

Err, since the duplicates appear in scancodes already, is the content of
dumpkeys really involved?

Evtest data does not show any additional events, so the additional scancodes must be coming from the legacy keyboard driver.

Sure, but dumpkeys shows the table from scancodes to keycodes, not from
input events to scancodes.

I am just wondering if some of the translation is leaking even though
the keyboard is in raw mode...

OK, scratch that... Are there any other input devices? Anything
connected via uinput and listening? What does /proc/bus/input/devices
show? Maybe if Tom could compile and load evbug module it would show us
where the additional events are coming form, becaus ethey surely are not
generated by the keyboard itself (otherwise we'd have seen them in
evtest output for that device).

Minor correction to what I wrote earlier about the scroll wheel. That is 
actually my mouse. It says Dell but it's really made by Logitech.

I just tried the console and what's funny is Favorites actually works as 
Capslock and Previous works as right-shift. X has the opposite problem.

In case anyone missed it, Debian Stable works fine with this keyboard. 
The keyboard on the working Stable machine is exactly the same (same usb 
id's). I'm not familiar with the input stack, but in case it is a kernel 
problem, the difference is:

Hmm, this keyboard registers 2 input devices... I wonder, if you press
CapsLock/Favories and RightShift/Previous and monitor both event devices
with evtest - will it report events on both devices at once?

I haven't really been following this thread but I think the two input devices
is normal if the keyboard has multi-media keys.  All the "extra" keys show up
as a separate input device.

You might get the CapsLock and RightShift events on one device and the Favorites
and Previous events on the other.

It is normal on sane devices however in this case there are "ghost"
key presses coming from an unknown source.

That thing I have been also wondering about when introducing the quirk for 
duplicate usages, but I haven't really found out. It's a bit odd.
