help with configuring hotplug

[Glenn Ramsey]

Hi,

I have been trying to get the hotplug stuff to work with usb but
have run up against a problem. It seems that the /sbin/hotplug
script is not being called by the kernel when a device is plugged.

What I want to happen is for the hotplug scripts to set the
permissions on the /proc/bus/usb/???/??? for my device, a scanner.
I have set up the required files as described in the README file
and it works if I invoke /sbin/hotplug manually.

I have an i386 Debian woody/sid system using kernel 2.4.3 I have
configured the hotplug option in the kernel.

I installed the hotplug scripts version of 20010424 from the sid
deb package and 
the latest usbutils rpm package from the link on the linux-hotplug
website.

Can anyone advise me on how to find out what is happening and how
to fix it?

Also if I turn on debugging in the scripts where does the output
go?

Here's the output from some relevant commands and log files... 

# cat /proc/sys/kernel/hotplug
/sbin/hotplug

# /etc/init.d/hotplug status

When I plug and unplug the device I see the following message in
the logs and on the console:
