usb keyboard translations

Hi,

When I plug a special purpose keyboard into the USB port, it creates a
/dev/input/event9
It then provides input to the terminal as though it was a keyboard.
Unfortunately, the key mappings are all wrong for this keyboard.
Is there some way I can do key translations between the the USB
keyboard and the terminal.
The problem is I only want the translations to occur to events from
/dev/input/event9 and not any other keyboard/mouse device that is also
plugged in.
Alternatively, is there a way that I can get these events to not even
reach the terminal, and allow me to write a daemon that would listen
to /dev/input/event9 and provide a interface to my specific
application.

Kind Regards

James
