[Bug 1247584] [NEW] [keymap] Since upgrade to Ubuntu 13.10, udev doesn't map middle mouse button.

[Launchpad Bug Tracker]

You have been subscribed to a public bug by Shock (mmiron):

On Ubuntu 13.04 I had the middle mouse button of my Logitech T400 mapped
correctly, but after upgrading to 13.10 the /lib/udev/kemap utility has
disappeared and now I can no longer assign the middle button to the
middle button function. This mouse has assigned by default the middle
button to the left_meta keyboard key (super key). That's very annoying
because I can't do middle clicking with this mouse. This mouse has two
middle buttons, in the trackpad that serves as middle wheel, but the
button that currently serves as middle click it's in a very
uncomfortable position, and the button with the left_meta functionality
is the one I'd like to use as middle button.

I tried modifying the file at /lib/udev/hwdb.d/60-keyboard.hwdb with
this rule:

keyboard:usb:v046DpC52B*
 KEYBOARD_KEY_700E3=middle

and also with

keyboard:usb:v046DpC52B*
 KEYBOARD_KEY_700E3=274

evtest returns the following results and codes:

BUTTON I WANT TO ASSIGN:
Event: time 1383485540.705610, type 4 (EV_MSC), code 4 (MSC_SCAN), value 700e3

THE BUTTON IN UNCOMFORTABLE POSITION

Event: time 1383485765.956075, type 1 (EV_KEY), code 274 (BTN_MIDDLE), value 1
Event: time 1383485765.956075, -------------- SYN_REPORT ------------
Event: time 1383485766.173978, type 4 (EV_MSC), code 4 (MSC_SCAN), value 90003
Event: time 1383485766.173978, type 1 (EV_KEY), code 274 (BTN_MIDDLE), value 0
Event: time 1383485766.173978, -------------- SYN_REPORT ------------

So, I would like to assign the BTN_MIDDLE function to the 700e3
scancode, but it does not work. With the previous utility included in
Ubuntu I could do this, but now with this SystemD way I can't do the
assignment.

I have not rebooted, but I did rebuild the hwdb database with the
"udevadm hwdb --update", and replugged the mouse.
