          Presently, we don't have a tested project.

            As of now, we do not have any code that is readily available for MASS Storage using PSoC5LP. However, you can implement Mass storage using PSoC5LP by modifying the descriptors fro the deivce. You can refer the descriptors for the device NX2LP which is available here, http://www.cypress.com/?id=196. You can copy the same descriptors from the source file for this device. At the same time, there are some specific USB requests that is associated with the Mass Storage device, your PSoC5 code should be capable of handling all these requests. You could straight away see how it is done for NX2LP and copy paste and edit to get it working.

              Thank you for your reply.

              It came to be recognized as a large capacity device according to USBFS component data sheet. After that, it is necessary to describe processing to respond with PSoC 5 LP to communication from the host side, but it is difficult
