AM335x USB data transfer

I am using Sitara AM335x board. I want to connect it to a host and start communicating through USB. Is it necessary to use the CPPI DMA for data transfer? what are the advantages of using it or disadvantages of not using it? Is it possible to build an application without using CPPI DMA?
