Our strategies seem to be different. You wrote a rule file with a high number, so that it is the last to be parsed and nothing *should* interfere with it. I wrote a rule file with a low number, so that it is parsed at the beginning excluding every interference from other scripts. The sintax for the option I mentioned is IIRC: OPTIONS="last_rule" The string as to be appended, after the usual comma, at the end of a given rule. This prevents that other rules are parsed against the same device. Other interesting info about what is involved in the process of creating devices are here: http://www.fedoraforum.org/forum/showthread.php?t=103665&highlight=udev+blac k+magic http://www.fedoraforum.org/forum/showpost.php?p=668532&postcount=4 Sorry if I can't be of more help.
