Will FTDI always converts the data into serial or any other types of transfers?
Answer to your question in short. FTDI chips implements USB protocol stack that is serial.
The FTDI cable is a USB to Serial (TTL level) converter which allows for a simple way to connect TTL interface devices to USB. The VCC pins of this FTDI cable are configured to operate at 5V with 3.3V I/O.
What happens inside the USB?
USB micro controller inside which talks a proprietary protocol over USB (hence the need for drivers) and converts that into "normal" UART signals and back again.
