I am making one USB model using C8051F38/B-GQ.

I have designed the circuit and want to program it using serial adapter EC2.

I selected C2 ad debug interface and EC2 serial adapter with port and baudrate.

I tried to connect the controller board with EC2 but it is not connecting.
my whole system is running on 5Vsupply but for programming I am using 3.3V which is generated by controller itset at pin 6 ie VDD.
Please reply so that I can discuss further issues and circuit for guidance
