<pre>Hi,
My remote presents itself (via an attached USB receiver dongle) as two devices,
a mouse and a keyboard. I'd like to map the mouse buttons to keyboard keys, but
have been unable to do so. Is this a bug, a missing feature, or a configuration
error on my part?
This is my remote:

This is what the kernel logs when I attach the dongle:

This is what evtest tells me about the mouse buttons when I click them:

This is what I've added to /etc/udev/hwdb.d/99-local.hwdb:
keyboard:usb:v0C45p2B02*
KEYBOARD_KEY_90001=select
KEYBOARD_KEY_90002=back
To make my changes to /etc/udev/hwdb.d/99-local.hwdb stick I run
# udevadm hwdb --update
# udevadm trigger
The original scancode/keycode mappings remain in effect, however.
I've tried replugging the receiver dongle and even rebooting, and I've also
tested with a bog-standard, three-button (wheeled) mouse, all to no avail.
This is what /proc/bus/input/devices has to say about the devices:
I: Bus=0003 Vendor=0c45 Product=2b02 Version=0110

Now, since mapping works perfectly with the keyboard device part of my
remote and another air mouse
<a href="http://forum.kodi.tv/showthread.php?tid=143571&pid=1499166#pid1499166">http://forum.kodi.tv/showthread.php?tid=143571&pid=1499166#pid1499166</a>
has been reported to work with a hwdb addition similar to mine
<a href="http://openelec.tv/forum/104-bluetooth-remotes/66542-help-configuring-keyboard-mapping-starting-3-1-6?start=15#90824">http://openelec.tv/forum/104-bluetooth-remotes/66542-help-configuring-keyboard-mapping-starting-3-1-6?start=15#90824</a>
I'm inclined to believe that (currently) for mapping to work for a particular
device, "kbd" has to be listed as a handler for that device. Is this correct?
If so, what can be done about it?
If you need more logs I can provide them. If you need me to test something I
can do that too.
My systemd is version 215 with various Debian (unstable) patches. I suspect
that does not make much of a difference.</pre>
