Explore a USB model for sharing host internet connectivity with devices in this 31-minute conference talk by Daniel Berliner from Xaptum. Delve into the problem description, motivating use cases, and the HSS (Host Sharing Standard) protocol. Learn about various packet types, commands like OPEN, CLOSE, SHUTDOWN, CONNECT, ACK, and TRANSMIT, and understand the concept of endpoints. Examine implementation requirements, focusing on Xaptum's device network driver approach. Follow the flow of an OPEN packet and overall packet flow, discuss challenges, and consider future developments in this field of USB connectivity sharing.
