Circuit and method for adaptively recognizing a data packet in a universal serial bus network device

摘要

A circuit for, and method of, adaptively recognizing a data packet (such as an Internet Protocol, or IP, packet) and a USB device containing a system-on-a-chip incorporating the system or the method. In one embodiment, the circuit includes: (1) a USB endpoint configured to receive USB packets bearing portions of the data packet and (2) a short packet detector associated with the USB endpoint and configured to detect and respond to a received short USB packet by causing at least some of the USB packets to issue from the USB endpoint.
