Right. I'm sorry, I wrote that by heart, I wasn't on a Linux box at the moment.
It actually means that you have a problem with either hotplug or udev.
I suggest you make sure udev is working properly, the outcome of the
command "cat /proc/sys/kernel/hotplug" should show "/sbin/udevsend" in
the case of using udev. Well, at least on Slackware.

Maybe /proc/sys/kernel/hotplug was meant. In this case I have to say, it
is available, but empty:
cat /proc/sys/kernel/hotplug
shows nothing.
