Problem with usb servo iocard

[asprueda]

I set up a usb servo iocard and recorded the hex file in microcontroller but gave no sign. I tested the circuit and everything is ok. I wonder if someone can provide me the hex file for me to test! This was the hex file that I recorded: http://www.opencockpits.com/images/IOcards/servo_motores/USBservos_10.hex.txt

Thanks!
