USB WEBMAIL NOTIFIER - Linux Script

Found a cheap USB LED Notifier at Radio Shack the other day, this code makes it go, I based this code on many random examples I found strewn around the interwebz let this be my official credit of their work 



#!/usr/bin/python
import usb
from optparse import OptionParser
from array import array

parser = OptionParser()
parser.add_option("-r", "--red", dest="red",
 help="Red Vaule")
parser.add_option("-g", "--green", dest="green",
 help="green Vaule")
parser.add_option("-b", "--blue", dest="blue",
 help="blue Vaule")

(options, args) = parser.parse_args()

dev = usb.core.find(idVendor=0x1d34, idProduct=0x0004)

try:
dev.detach_kernel_driver(0)
except:
pass

msg = bytearray('\x00\x00\x00\x00\x00\x00\x1a\x05')

msg[0] = int(options.red)
msg[1] = int(options.green)
msg[2] = int(options.blue)

dev.ctrl_transfer(0x21, 0x09, 0x0200, 0x000, msg)
