hardcode a device using udev

hi

My touchscreen "LG Display LGD-MultiTouch" will be recognized sometimes as /dev/input/event0 and sometimes as /dev/input/event3.
Howto hardcode /dev/input/event0 using udev and xorg.conf?

Code:

# cat /proc/bus/input/devices

I: Bus=0003 Vendor=1fd2 Product=0064 Version=0100

N: Name="LG Display LGD-MultiTouch"

P: Phys=usb-0000:00:1d.7-4.1/input0

S: Sysfs=/devices/pci0000:00/0000:00:1d.7/usb1/1-4/1-4.1/1-4.1:1.0/input/input0

U: Uniq=

H: Handlers=mouse0 event0 

B: EV=1b

B: KEY=403 0 30000 0 0 0 0 0 0 0 0

B: ABS=700 3f

B: MSC=10





# udevadm info --query=all --path=/devices/pci0000:00/0000:00:1d.7/usb1/1-4/1-4.1/1-4.1:1.0/input/input0

P: /devices/pci0000:00/0000:00:1d.7/usb1/1-4/1-4.1/1-4.1:1.0/input/input0

AFAIK the best page is still Daniel Drake's. It is outdated in that the udevinfo command is replaced by udevadm with the info option.
