Bug#821389: xinput: please support distinct device IDs

[Harald Dunkel <harald.dunkel@aixigo.de>]

On the previous reboot it was 4 and 6 (IIRC), thats the
point of this ticket. And the suggested "pointer:Logitech
USB Receiver" doesn't work either. Not to mention that
there is only one USB receiver plugged in.

Using xorg.conf to configure the device there was no
problem like this. I could write

Section "InputDevice"
    Identifier     "Logitech USB Receiver"
    Driver         "evdev"
    Option         "Dev Name" "Logitech USB Receiver"
    Option         "Device" "/dev/input/by-id/usb-Logitech_USB_Receiver-event-mouse"
    Option         "Emulate3Buttons" "yes"
    Option         "ButtonMapping" "1 8 3 5 4 6 7 2 9 10 11 12 13 14 15 16 17 18 19 20"
EndSection

to configure the mouse. Since this configuration scheme has
been deprecated with xinput2, its the job of /usr/bin/xinput
to take over.
