>python setcolor.py 5 fails on windows with libusb-win32

[GoogleCodeExporter]

I tried to get the setcolor.py script working under windows 7 but without 
success.

A) PREPARATION
I installed the following modules
- usb
- libusb-win32

To verify the installation I tried to find the usb mail notifier in a python 
shell. This works successfully with:
>>> import usb.core
>>> dev = usb.core.find(idVendor=0x1d34, idProduct=0x0004)
>>> print dev
<usb.core.Device object at 0x023BB750>

B) EXECUTION FAILURE
But I'm not able to get the setcolor.py script working. It failes with the 
follwoing messages:
C:\Users\dieterled\Desktop\Neuer Ordner>python setcolor.py 5
Traceback (most recent call last):
  File "setcolor.py", line 60, in <module>
    main(sys.argv)

    raise USBError(errmsg, ret)
usb.core.USBError: [Errno None] libusb0-dll:err [control_msg] sending control 
message failed, win error: Das System kann
 die angegebene Datei nicht finden.

The last german message means: The system can not find the given file.

C) SOLUTION
To get it working under windows 7 I wrote a new class for the usb mail notifier 
based on the pywinusb module. The steps to get it working are:
1. Deinstall libusb-win32 driver
2. Install the default windows driver for the usb mail notifier
3. Install the pywinusb module (this may require to install additional python 
modules/packages)
4. Install the usbMailNotifier.py module attached to this issue.

I have forgotten the USB Mail Notifier initialization sequence.
