Dotaz: udev a event

[vlk]

ahoj, uz dlhsiu dobu ma trapia problemy spojene s udev a event

konkretne potrebujem aby sa mi touchscreen identifikoval ako konkretne zariadenie, nakoniec sa mi podarilo napisat pravidlo pre udev, ktore vytvori symlink.. ale ma to jeden maly hacik, ze funguje len kazdy druhy restart :-/

toto pravidlo je:

SUBSYSTEM=="input", ATTRS{idVendor}=="1bfd", ATTRS{idProduct}=="1688",
 ATTRS{product}=="HID Touch Panel", SYMLINK+="touchevent"

 

a ten touchscreen sa mi identifikuje takto:

samozrejme kazdym restartom ma event ine cislo

netusi niekto kde mam chybu, alebo preco to nejde?

distribucia je debian testing a hardware je "asus eee top"

Tvoj udev nevytvára v /dev/input adresár by-id? (ak áno, tak by si možno mohol použiť odkazy, ktoré sa tam vytvárajú)
