hello all, at what frequency should the USB1.1 core be running at? the FPGA synthesizer gave me a maximum of 38MHz is this enough? the Board I am using has a 50 MHz osclillator, Should I replace the ocsillator on the board, (I am using Xilinx Spartan 30Kgates ), I couldnt find a way for frequency division. sincerely Abukhater --------------------------------- Do you Yahoo!?
