# Goal :
#       This script handles the ADI ADSL Modem USB driver after firmware
#       uploading. It loads the DSP code as needed by the modem.
#       It create a script /var/run/usb/%proc%bus%usb%002%005 in order
#       for the ADSL connexion to be stopped and module to be unloaded.
#   It should only be run by hotplug.
# Params (given by hotplug) :
#       $DEVICE  ex: /proc/bus/usb/002/005
#       $DEVPATH ex: /devices/pci0000:00/0000:00:02.0/usb1/1-2/1-2:1.2
#       $REMOVER ex: /var/run/usb/%proc%bus%usb%001%006
#       note: only kernels 2.5+ provide $DEVPATH
#       note: some distribs like SuSE9.1 does not provide $REMOVER param

# the following line will be replaced by the absolute path of setvars
. /etc/eagle-usb/setvars

# this script should only be called by hotplug (giving the $DEVICE param)
