Sorry I am new to SAM3 - previously been using PIC and Cypress USB controllers. I want to use the SAM3 part to accept a USB bulk command on an EP link, process i and send it back on another link. I will be using libusb to send/receive the bulk commands from linux/windows. Atmel directed me to the "usb_core" example but this is a little brief and it is hard to know where to put in my code etc to respond to arrival of an outbound transfer.
Does anyone have any expereince with using "usb_core". Is there some kind of hello_world for this? The HID example is much better but I am afraid HID is too slow for our application.
Any responses would be helpful,
