# This an example of how to get a 'hook' into a USB event.
# You may need to create the directory /etc/hotplug.d/usb
# Then place this file inside the directory and make sure it's executable
# the name doesn't matter and all the echos are just verbosity for
# debugging. The main thing is to run your external script if certain
# conditions are met. The example script here is /usr/sbin/do-hotmnt
# We have to export any of the variables we need to exec and background 
# the new process so this hook can exit.
# ACTION DEVICE and INTERFACE are probably all we need (maybe DEVFS)

# The only ACTION cases supported by the USB driver are 'add' and 'remove'
# If you need to handle events when the usb-storage module is loaded, put them
# in /etc/hotplug/usb-storage

cd /etc/hotplug
. ./hotplug.functions

# uncomment to activate hotplug messaging.  You can also use 'mesg'
# DEBUG=yes export DEBUG
debug_mesg "arguments ($*) env (`env`)"

# you can use some kind of logging the /var/log/messages or elsewhere
#echo "Hello from /etc/hotplug.d/usb/usb-stub.hotplug" >> /var/log/messages

# since this hook is run by the kernel as root, we try to get out of here as soon
# as possible. We start a separate process (do-hotmnt) to handle events from
# the usb-storage driver and automatically mount and unmount the partitions
# on the device
