OK, great -- that moves your problem from PyUSB to libusb, which is  
useful to know. The PyUSB page lists supported operating systems only  
as "Linux" which is partly what threw me off.

Whoa, why are we discussing Windows all of a sudden?

You don't have to do anything special to get the Python compile step  
to look in /usr/include or /usr/local/include.

Can you post the output from this command?
find /usr -name usb.h -ls

Also post the output you get when you run this for PyUSB:
sudo python setup.py install
