USB Low-Full-High Speed Peripherals

        Hi,   
   
I've written a C++ program using CyAPI.lib that alternately writes "AA" and "55" using the Xferdata() method into an isochronous endpoint buffer on the CY3684 development board. I'm using slave FIFO Auto mode of operation, with the SLRD pin grounded for permanent assertion. I'm hoping to see a waveform when I hook my scope to any of the FD[0-7] lines on the dev board, I see only noise. I'm fairly sure my firmware is fine, but I'm wondering if there are any obvious registers I omitted or something I'm forgetting to do that could produce this problem.   
   
Thanks for any advice you can offer,   
Zach

        Did you hardware the endpoint from which you are expecting data using the FIFOADR0 and FIFOADR1 lines????
