title: How to set up libusb on Mac OS X?
body: <p>I'd like to try to make a user-space device driver using libusb on Mac, but I'm confused where to start. In the SDK installer (which I got from <a href="http://www.ellert.se/twain-sane" rel="noreferrer">http://www.ellert.se/twain-sane</a>) it said something about examples which I couldn't find anywhere on my computer.</p>
  
  <p>Could anyone please describe how do I set up libusb for development on OS X? May I use Xcode? What should I include in my code?</p>
