Public bug reported:
I have a small gaming keyboard (Ideozon Fang) which has a terrible
default keymapping that I want to fix. To do that, I need to change its
default keymapping. But only for that keyboard and no other. My system
is Ubuntu 14.04 (amd64).
As an example, I will change the key '3' which is by default mapped to
'Numpad 3' to 'PgDn'.
The old way that used to work (and still does in Debian 7.6) was this:
<----- snip ----->
root at debian~# /lib/udev/keymap -i /dev/input/event7
Press ESC to finish, or Control-C if this device is not your primary keyboard
scan code: 0x7005B key code: kp3
root at debian~# cat /etc/udev/keymaps/ideazon-zboard
0x7005B pagedown
root at debian~# /lib/udev/keymap /dev/input/event7 /etc/udev/keymaps/ideazon-zboard
Remapped scancode 0x7005b to 0x6d (prior: 0x51)
root at debian~# evtest /dev/input/event7
Input driver version is 1.0.1
Input device ID: bus 0x3 vendor 0x1038 product 0x310 version 0x111
Input device name: "Ideazon Zboard USB Gaming Device"
[...]
Event: time 1408993871.777960, type 4 (EV_MSC), code 4 (MSC_SCAN), value 7005b
Event: time 1408993871.777971, type 1 (EV_KEY), code 109 (KEY_PAGEDOWN), value 1
<----- snap ----->
However, this method does not work anymore in 14.04 (for instance, there
is no 'keymap' utility). Now, if I researched it correctly, we are
supposed to do this:
<----- snip ----->
root at ubuntu:~# lsusb | grep -i ideazon
Bus 003 Device 009: ID 1038:0310 Ideazon, Inc.
root at ubuntu:~# cat /etc/udev/hwdb.d/91-local-ideazon-zboard.hwdb

Event: time 1408993986.205654, type 1 (EV_KEY), code 81 (KEY_KP3), value 1
<----- snap ----->
But, as you can see, it does not work. 'evtest' still reports the key as
'Numpad 3'. Even unplugging and re-plugging the keyboard has no effect.
'udevadm' seems to compile my custom file alright (it complains if I
purposefully put a syntax error in it). But I still cannot redefine my
keymap.
I do not know if this is a problem of the newer udev itself. But even if
it is, Ubuntu should not use it until it actually works. Especially not
in a LTS version.
