Enable Keyboard Plug And Play

[frost]

Hello everybody,
my name is frost (felix) and this is my first post in this community.

The problem I am struggeling with is to enable plug and play for my keyboard. I already searched the forum for 'plug and play', 'keyboard', 'kernel', 'modules' and so on, but did not find what I am looking for. Hopefully someone out there can help me!

What I want:
Put in the keyboard on the usb port while xbian is already running and then use the keyboard.

What I already tried:
I figured that the kernel modules evdev and joydev are responsible for controlling my keyboad. If the keyboard is plugged at boot time, they are loaded and evdev is used (according to lsmod).
lsmod output with plugged keyboard at boot time:

Terminal

xbian@xbian ~ $ lsmod
Module Size Used by
fuse 69258 3
nfsd 259835 2
bcm2708_wdog 3530 1
snd_bcm2835 13087 0
snd_pcm 77296 1 snd_bcm2835
snd_page_alloc 5196 1 snd_pcm
snd_timer 19974 1 snd_pcm
snd 58448 3 snd_bcm2835,snd_timer,snd_pcm
evdev 9489 2
joydev 9340 0

In comparison lsmod with no keyboard at boot time (evdev and joydev are not there):

Terminal

xbian@xbian ~ $ lsmod
Module Size Used by
nfsd 259835 2
fuse 69258 3
bcm2708_wdog 3530 1
snd_bcm2835 13087 0
snd_pcm 77296 1 snd_bcm2835
snd_page_alloc 5196 1 snd_pcm
snd_timer 19974 1 snd_pcm
snd 58448 3 snd_bcm2835,snd_timer,snd_pcm

My first idea was to simply reload the missing modules after the keyboard is plugged via modprobe. Loading the modules did work, however they were not used. Then I modified the /etc/modules file in order to always load evdev and joydev at boot time.
Again loading the modules works fine - but when I plug the keyboard afterwards the modules are simply not used but according to lsusb the keyboard is recognized just fine:
lsmod and lsusb with preloaded modules and afterwards plugged in keyboard:

Terminal

xbian@xbian ~ $ lsmod
Module Size Used by
evdev 9489 0
joydev 9340 0

snd_page_alloc 5196 1 snd_pcm
snd_timer 19974 1 snd_pcm
snd 58448 3 snd_bcm2835,snd_timer,snd_pcm
xbian@xbian ~ $ lsusb

As you can see, evdev is 'used by 0'.
My question: can I somehow convince my hardware to use the module? Or am I on the completely wrong way and need to do something different to enable plug and play?
Just to make this clear: I dont care for general plug and play - just the keyboard is enough.

Thanks for reading till this spot Please help me if you can!
