cypress fx3 usb 2.0 VGA 15fps

Hi,

I am using AN75779 example code.

I am trying to stream VGA resolution 15fps over USB 2.0.

But the sample application is for super speed configuration like

CY_FX_EP_BULK_VIDEO_PKT_SIZE 1024bytes

.burstLen = 16;

but USB 2.0 bulk will support 512bytes and burst len 8

i am getting black screen..

Any suggestion?
