Hi,
What is the device connected to GPIF II port of FX3?
Is it an FPGA?. Did you look at the projects that are attached to the following application note:
http://www.cypress.com/?rID=51581
It look like you are able to fill the 16KB of buffer allocated to that DMA channel and then I am not sure whether you are reading that buffer from the USB side. Please share more details of your application.
Thanks,
sai krishna.

Hi,
Please check whether you have this piece of code in main function of FX3 firmware. If not, please add it.
CyU3PSysClockConfig_t clkCfg = {
CyTrue,
2, 2, 2,
CyFalse,
CY_U3P_SYS_CLK
};
/* Initialize the device */
status = CyU3PDeviceInit (&clkCfg);
if (status != CY_U3P_SUCCESS)
{
goto handle_fatal_error;
}
Thanks,
sai krishna.
