How can PyUSB be understood? [closed]

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this 开发者_高级运维question so that it can be reopened, visit the help center. Closed 11 years ago.

I am unable to proceed on how PyUSB works. I am stuck for a week now. How do I proceed?

At first glance, documentation for PyUSB seems to be entirely absent. But not so.

From a Python prompt you can:

 >>> import usb
 >>> help(usb)

And it turns out to have documentation!

 >>> help(usb.core)

Was quite useful. It seems quite straightforward.
