Refer to the Application Notes USB Peripheral Basics - AN57294 at

You need to configure your PSoC as a bulk device that transmits data to the host(PC) continuously. The DMA has to be

configured to have ADC as source and a memory buffer as destination.

Refer to this Application Note to learn about DMA Using DMA on PSoC® 3 / PSoC 5 - AN52705
