# lsusb (list USB devices) utility for Mac OS X
# Author: JLH, Sep 2013
# Usage:
#
# lsusb [ options ]
#
# Options:
#  -v  
# 	 Print the original output of `system_profiler SPUSBDataType`
#
#  -d [vendor][:product]
#              Show only devices with the specified vendor and product ID.  Both ID's are given in hexadecimal.
#
# Disclaimer: some part of the usage info has been taken from the manual of lsusb(8), I take no credit for it.

# Save the data from the system_profiler command
