Comment 4 for bug 1247584

Ok, first of all, the keymap which I had stored in /lib/udev/keymaps in a
file named logitech-t400 is like follows:

0x700E3 0x112

And here is my old udev rule which used the keymap program:

ACTION=="remove", GOTO="mouse_end"
KERNEL!="event*", GOTO="mouse_end"
ENV{ID_INPUT_KEY}=="", GOTO="mouse_end"
SUBSYSTEMS=="bluetooth", GOTO="mouse_end"

SUBSYSTEMS=="usb", IMPORT{builtin}="usb_id"
SUBSYSTEMS=="usb", GOTO="mouse_usbcheck"

LABEL="mouse_usbcheck"

SUBSYSTEM=="input", ENV{ID_VENDOR}=="Logitech*", ATTRS{name}=="Logitech
Unifying Device*", RUN+="keymap $name logitech-t400"

LABEL="mouse_end"

LABEL="mouse_modulecheck"

> Bug description:
> 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.
