This demo is provides a description of how to use the USBD peripheral. It illustrates an implementation of the CD-ROM which uses the bulk transfer while the internal Flash is used as storage media. This example supports the BBB (bulk only transfer) protocol and all needed SCSI (small computer system interface) commands, and is compatible with Windows platform. After running the example, the user just has to plug the USB cable into a PC host and the device is automatically detected. A new CDROM appears in the system window and the user can open it to read the contents.
