      Hi

         

        I use the following this method tried to reset a DMA channel in the slave sync fifo example

         

         CyU3PDmaChannelReset(&glChHandleSlFifoPtoU);
           /* Flush the Endpoint memory */
               CyU3PUsbFlushEp(CY_FX_EP_CONSUMER);
               /* Set DMA channel transfer size. */
               CyU3PDmaChannelSetXfer (&glChHandleSlFifoPtoU, CY_FX_SLFIFO_DMA_TX_SIZE); 

         

         In USB2.0 mode is executed with operation no problem,But in USB3.0 mode will be a mistake .how to solve?
