isochronous transfer question

I'm using the MCB2140 board with the philips LPC2148 chip.

I am looking to do an isochronous transfer back to the pc from the device. I have the endpoints setup and start of frame enabled. I have my code that writes to the IN endpoint inside of the start of frame section.

Currently I am not seeing anything on the PC. I was wondering if I have my embedded side setup correctly, or if there are any examples of using isochrous endpoints.

Thanks
Aaron
