How Can PyUSB Be Understood?

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

Solution 1:

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.
