How to increase the Pipe transfer rate on USB 3.0 for XEM8320

I want to increase the Pipe API transfer rate to a multiple of 16 for USB 3.0 (XEM8320). I have changed the line "sample = bytearray(b’0000000000000000’) " in the file, but it does not work. Here, FrontPanel API - Opal Kelly Documentation Portal it is mentioned that “Firmware restrictions put a limitation on the maximum length per transfer”. Request you to kindly provide a solution so that I can increase the transfer rate to 32 or 64 or even higher.
