Hi Shawn,
Could you please specify which WiFi module are you referring to and what do you need to verify? Also, first you mentioned USB0 but then you mentioned USB1, please clarify.
It is true that we have several USB examples in our SDK, implementing different USB classes. If you need a more general idea of what our examples do, there is a readme.pdf file included in the SDK folder that it will describe with details the application of each one of them.
Best regards,
Felipe
