Olimex Atmel SAM9-L9260 USB Configuration code

Hi,

I am trying to interface USB flash drive to the Olimex development board SAM9-L9260. There is an on board USB host connector with USB A type connector that I would be using. I was wondering if there is any type of USB configuration test code available that I can use to understand coding. Any help is greatly appreciated.
