# This script simply runs "rescan-scsi-bus -l" to look for devices
# that have been plugged into a USB or IEEE1394 (Firewire) port that
# might not have been detected because they use a LUN (Logical Unit
# Number) other than 0.
#
# You might need to run this script again (or just use
# rescan-scsi-bus directly at the command line) after plugging
# in new devices such as USB cameras, music players, external
# storage, and similar items.

# Run this only if "noscanluns" was NOT given as a kernel option.

# Options like "start", "stop", and "restart" are meaningless here

# and "eject" commands to safely remove a device, though.
