This application note describes the four USB transfer types: Interrupt, Bulk, Isochronous, and Control.

AN56377 describes the four USB transfer types: Interrupt, Bulk, Isochronous, and Control. It then shows how to configure PSoC® 3 and PSoC 5LP to perform each of these transfers. Code examples are also included for specific considerations, including vendor commands for custom USB functionality, and to use DMA for faster data throughput. This application note assumes a basic-level knowledge of USB and is intended as an initial hands-on introduction to USB on PSoC 3 and PSoC 5LP. For a general introduction to USB, see AN57294.

Below are some of videos demonstrating  how to impliment bulk transfers and vendor commands which are discussed in this application note.
