Getting familiar with USB on your own can be intimidating task, especially if you have no prior USB programming experience. Hopefully the talk will provide clear enough explanation so you can avoid scratching your head due to common misconceptions. During the talk a Zephyr-based device traffic captured both at a URB level (USBPcap) and USB packet level (OpenVizsla) will be discussed.
