    CYUSB3014 does not work with PktEnd signal if data size more than or equal 1kB

      Hello, may be you can help me

         

      I use CYUSB3014 with FPGA bus 32 bits, 50 MHz, don't work correct Bulk In EndPoint.

         

      All work good if i commit data buffer used PktEnd signal with 1-255 DWORDs (4 - 1020 byte). But if i use PktEnd signal for more data, USB Monitor write me USB device 'Surprisingly removed'.

         

      If i don't use PktEnd signal USB device send data only than packed buffer full, each pack 16384 bytes, but if buffer not full does not send data.
