Hello, I am totally new to USB (well, at least to the darkness inside ;-( I have to read data from an FPGA located behind the TD245. My question i : who begins the data transfer? if I program the FPGA to read say 1k bytes does the FPGA have to begin filling up the FIFO and suppose that the dat will be caught on time by the DLL, or does the FPGA have to track the TX ("transmit enable") and respond each time? Sorry for the beginner's status... and many many thanks for the futur replies :-) Jean Louis
