# This script, sadly, is distinct from gobi-modem-reset.c in gobi-cromo-plugin.
# gobi-modem-reset is meant to be run setuid with a single USB ID as its target;
# this script is run from an upstart job (i.e. already as root) before we know
# the USB ID of the device. This script could be made to just determine the USB
# device IDs and then invoke gobi-modem-reset, but it seems kind of dirty to
# introduce a dependency between packages for such a trivial piece of
# functionality.
