# This script changes the permissions and ownership of a USB device under
# /proc/bus/usb to grant access to this device to users in the usb group
# and the first user that logged in.
#
# Ownership is set to $USER.usb, where $USER is the first user that logged
# in (through pam_console). If there is no user logged in, the ownership
# will get set to root.usb. Permissions are set to 0660.
#
# Arguments :
# -----------
# ACTION=[add|remove]
# DEVICE=/proc/bus/usb/BBB/DDD
# TYPE=usb
