    FX3 EP0 write/read delay?

    milkfish1227_2635671

      Hi,

      I am working on a Windows console application to write/read EP0. FX3 firmware doesn't do anything other than loopback the data get from EP0.

       

      The Windows console application EP0 Read() takes about 5-6 seconds to complete. See code below -

       

         bXferCompleted = ctrlEpt->Write((PUCHAR)puc_buf_out, (LONG &)ul_len);

       

         bXferCompleted = ctrlEpt->Read((PUCHAR)puc_buf_in, (LONG &)ul_len);

       

      Is there any reason why the EP0 Read takes so long to complete?

       

      Thanks,

      Dick
