    Data transfer between FPGA over USB interface to processor (Host USB)




      Please refer the attached representation. I have implemented an USB PHY using Cypress FX2LP CY7C68014A USB Controller between FPGA and processor. Processor has an USB host.


      On a command received from processor (over USB), FPGA should send a stream of data back (over USB).


      I have developed firmware to transfer data from USB controller input (D+/D-)  to FPGA (over 8 bit parallel) , but how should I transfer data recieved by USB Controller (FX2LP) from FPGA (8 bit parallel) to processor (over USB, D+/D-) over USB.


      Can someone help me with this..


      Thanks in advance,
