Hi Dan et al,
what you experience is the same to what I see in my older z60m. A solution would be great :)

Anyway, you may find these

http://lists.freebsd.org/pipermail/freebsd-mobile/2006-August/008959.html

useful wrt to handling devd and custom scripts... AFAIK, you don't need sysctl values to be changed for devd events to be triggered, but I could be wrong.
