HI there,

i have two questions to the Xylo-L board.

C# with CyUSB driver.
bidir communication to the FPGA (Spartan3).

1) i use the Scream-demo to check maximum speed of the board, but only in bulk-mode the speed is up to 30mb in isocron and interrupt mode it's only 4mb, Why? any ideas?

2) i can only use the endpoints with the adress 0x02 and 0x86, why?

must i programm the cypress-chip myself or is the defauft configuration adequate?

thanks for reply

Please provide a pointer to the demo you reference and I'll try and reproduce your results.
