I have an C120 air mouse remote. It has a 2.4GHz dongle, no IR functions, keyboard on the back and navigation buttons and mouse button on the front. (link)
My system is a DELL Wyse thin client with an Intel CPU, running LibreELEC 12.0.2 and Kodi 21.2.0.

The remote works fine in Kodi in mouse mode and in regular mode, except 3 buttons: volume up/down and back.

In LibreELEC, I have identified these events linked to the remote:
* event6: the 3 missing keys (and only those)
* event7: all working buttons (navigation and the backside keyboard)
* event8: mouse movement and buttons (when remote is in mouse mode)

Although they produce the expected output with evtest, the 3 event6 buttons do not give any code in the Kodi keymap editor.

Output of cat /proc/bus/input/devices for the ones linked to the remote is below.

Any suggestions?

(note: this is a different remote from my earlier questions. I got this one hoping it would work since it is a bit more simple, but alas.)

I guess the problem is this maybe?

from the output of udevadm info /dev/input/event3:

E: ID_INPUT=1
E: ID_INPUT_TABLET=1
E: ID_INPUT_TABLET_PAD=1
E: ID_INPUT_KEY=1

but I don't know how to fix that.

I created the 70-local-keyboard.hwdb file:

evdev:input:b0003v1915p1025*
 KEYBOARD_KEY_c00b4=enter

and then abit modified from post #9 (deprecated command):

systemd-hwdb update
udevadm trigger -s input

now the KEY_REWIND shows up as KEY_ENTER:

Event: time 1751810063.011279, type 4 (EV_MSC), code 4 (MSC_SCAN), value c00b4
Event: time 1751810063.011279, type 1 (EV_KEY), code 28 (KEY_ENTER), value 0

but Kodi still ignores it.

However here it seems to think event3 is mouse? I somehow can't get proper output from the command, it messes with the console

udevadm info /dev/input/event3

It looks similar to wha is described in posts #20-#25, however this is on a Kodi/libreelec install straight from the official page. The remote is linked to 3 events: 1 for the mouse, #4 for the regular (working) keys and #3 for the 'multimedia' keys.

supposedly kodi can see all:

Wyse5070:~/.config/hwdb.d # lsof |grep /dev/input
506     /usr/lib/systemd/systemd-logind 10      /dev/input/event4
506     /usr/lib/systemd/systemd-logind 16      /dev/input/event1
506     /usr/lib/systemd/systemd-logind 17      /dev/input/event0
506     /usr/lib/systemd/systemd-logind 18      /dev/input/event3
2438    /usr/lib/kodi/kodi.bin  17      /dev/input/event2
2438    /usr/lib/kodi/kodi.bin  18      /dev/input/event3
2438    /usr/lib/kodi/kodi.bin  19      /dev/input/event4
2438    /usr/lib/kodi/kodi.bin  20      /dev/input/event5

but the log shows no presses for event3 (it does for event4):

At the end I pressed the '1', '2', '3' keys (which show) and then a bunch of the multimedia keys (but they don't show up).

Thanks!
These are linked to a seperate 'event' from the regular keys. In rough order of appearance on the remote:
KEY_REWIND
KEY_FASTFORWARD
KEY_PREVIOUSSONG
KEY_NEXTSONG

KEY_SEARCH
KEY_PLAYPAUSE
KEY_ZOOMIN
KEY_ZOOMOUT

KEY_HOMEPAGE
KEY_BACK
KEY_VOLUMEUP
KEY_VOLUMEDOWN
KEY_MUTE

KEY_CONFIG
KEY_MAIL
KEY_WWW

I guess all of these are not recognised by Kodi and there is recent discussion on that: https://github.com/xbmc/xbmc/issues/26884

It's clear to me if there is a timeline on the fix yet. So I'll get back to post #9. I'll report back how far I get...

Just to add that the remote button presses on the multmedia buttons do not show up in the kodi log file.

I have a new MX3 style remote, that is working fine on Windows, but Kodi on LibreELEC 12.0.2 does not recognise the multimedia keys. All other keys are working fine, but e.g. vol+/vol-, ffwd/rev etc. don't work.
In the Kodi keymapper addon there are not codes received when I press any of those keys.

Vendor ID is 1915 product ID is 1025.

I tried adding to 51-these-are-not-joysticks-rm.rules, but no change (and it seems like it was properly recognised as a keyb/mouse anyway.

Trying to follow post #9 instructions I get stuck since evtest is not found. And maybe that wouldn't work over ssh anyway?

Any tips?
