I still don't see how udev is at fault here, as you see no log messages from it. Didn't you also do a "echo /bin/true > /proc/sys/kernel/hotplug" to disable udev and the hotplug events entirely and still had the problem? That rules out udev. thanks, > http://linuxusb.bkbits.net:8080/udev/cset@1.759?nav=index.html|tags|ChangeSet@..1.7601 > Symptons of problem: When cron executes a bash script, /dev/null changes > from the permissions lists in udev.rules to 600.

I thought the other script you posted just watched what happened in /dev, right? thanks, greg k-h ------------------------------------------------------- This SF.Net email sponsored by Black Hat Briefings & Training.
