I think that in the pyusb tutorial:
http://pyusb.sourceforge.net/docs/1.0/tutorial.html
That under the "Let's get it started" sub-section the line:

alternate_settting = usb.control.get_interface(interface_number)

should be

alternate_settting = usb.control.get_interface(dev,interface_number)

This is because in control.py there are two arguments:

def get_interface(dev, bInterfaceNumber):

There are also too many t's in alternate_settting. It is spelled more conventionally later.

Apologies if this is wrong or has been brought up already.
