Library for Official USB Host Shield (A000004)

I'm having trouble finding the library that supports the official (arduino) USB Host Shield. The libraries that I see look like they are intended for other specific hardware. Could someone point me in the right direction?

Thank you,
Kevin

Arduino Library

The Arduino USB Host Shield can be used with the "USB Host Library for Arduino" hosted by Oleg Mazurov and Alexei Glushchenko from circuits@home, Kristian Lauszus and Andrew Kroll onGitHub (download).

Thank you. I'd been having trouble with that and was beginning to wonder that I'd installed the wrong thing.

Thank you
