I'm using Ubuntu 14.04 dev with xserver-xorg-core 2:1.14.5-1ubuntu2 and if a device is unplugged and plugged it will change its previous configuration. Here is what I get after login into my desktop:

sworddragon@ubuntu:~$ xset -q
Keyboard Control:
  auto repeat: on key click percent: 0 LED mask: 00000000
  XKB indicators:
    00: Caps Lock: off 01: Num Lock: off 02: Scroll Lock: off
    03: Compose: off 04: Kana: off 05: Sleep: off
    06: Suspend: off 07: Mute: off 08: Misc: off
    09: Mail: off 10: Charging: off 11: Shift Lock: off
    12: Group 2: off 13: Mouse Keys: off
  auto repeat delay: 500 repeat rate: 33
  auto repeating keys: 00ffffffdffffbbf
                        fedfffefffedffff
                        9fffffffffffffff
                        fff7ffffffffffff
  bell percent: 0 bell pitch: 400 bell duration: 100
Pointer Control:
  acceleration: 20/10 threshold: 10
Screen Saver:
  prefer blanking: yes allow exposures: yes
  timeout: 0 cycle: 0

  default colormap: 0x20 BlackPixel: 0x0 WhitePixel: 0xffffff
Font Path:
  built-ins
DPMS (Energy Star):
  Standby: 600 Suspend: 7200 Off: 14400
  DPMS is Disabled

And this after unplugging and plugging the mouse and keyboard:

sworddragon@ubuntu:~$ xset -q
Keyboard Control:
  auto repeat: on key click percent: 0 LED mask: 00000000
  XKB indicators:
    00: Caps Lock: off 01: Num Lock: off 02: Scroll Lock: off
    03: Compose: off 04: Kana: off 05: Sleep: off
    06: Suspend: off 07: Mute: off 08: Misc: off
    09: Mail: off 10: Charging: off 11: Shift Lock: off
    12: Group 2: off 13: Mouse Keys: off
  auto repeat delay: 660 repeat rate: 25
  auto repeating keys: 00ffffffdffffbbf
                        fadfffefffedffff
                        9fffffffffffffff
                        fff7ffffffffffff
  bell percent: 50 bell pitch: 400 bell duration: 100
Pointer Control:
  acceleration: 2/1 threshold: 4
Screen Saver:
  prefer blanking: yes allow exposures: yes
  timeout: 0 cycle: 0
Colors:
  default colormap: 0x20 BlackPixel: 0x0 WhitePixel: 0xffffff
Font Path:
  built-ins
DPMS (Energy Star):
  Standby: 600 Suspend: 7200 Off: 14400
  DPMS is Disabled

Some values have changed and I'm assuming that the second one from the mouse and keyboard are the default ones from the X-Server. As this changes the usability in an unexpected way maybe Ubuntu should take care that it keeps always the same values for example with the help of udev.
