Cypress Sample program question

I'm using the Cypress FX-2 board.
They include a sample called bulkloop.c
that allows you to loop data out to BULK IN EP's 2 & 4 and back via BULK OUT EP's 6 & 8. When i try this the Host Writes to EP's 2 & 4 go just fine but Host Reads from EP's 6 & 8 always send a NAK back to the host. The code for the FX-2 looks simple enough but I cant figure out why BULK IN EP's 6 & 8 always NAK.
Is anyone else working with this board?
I'd sure like to bounce information and ideas around.

Also are there any other forums around for this, any other sample code available anywhere? I'm looking for resources.

Thanks
