UDEV rules for touch screen NOT working

[mbertrand]

I have a rules file for persistent naming of device node for touch screen.
On some systems we build, the touch screen is /input/event1 and on others it is /input/event2.
This rule was working on Debian Sqeeze but now I've switched to Tiny Core and is not working.

SUBSYSTEM=="input", KERNEL=="event*", ATTRS{idVendor}=="07dd", NAME="input/touchscreen"

Also, where can I get log files regarding udev at boot.
