I could not understand how You can Share The Pain with this.

Under 2.6.XX You must change kbd_connect() drivers/char/keyboard.c and
mousedev_connect() drivers/input/mousedev.c - in all conscience
kbd_connect,()
because redundant /dev/input/mouseXX do not distrub any.
Please add
if(!strcmp(dev->phys,"usb-foo-bar/input0")
     return NULL;

or

if(!strcmp(dev->name,"belkin n52")
     return NULL;


n52 device physicaly description "usb-foo-bar/input0" You should grab from
/proc/bus/input/devices
P: Phys=usb-foo-bar/input0
