What do you mean? Can I decouple the AVR from the FTDI chip and then use the FTDI to interface the dosonchip module to the USB port?
I meant decouple the AVR from the FTDI and use the AVR's UART to talk to the dosonchip module, although now that you mention it you could pull the AVR from its socket and use the FTDI to talk to the dosonchip.
