Re: Nov 28 - Day 3: Understanding the USB Protocol

NO RATINGS
JVonHatten; I do not think so. USB data packets are sent in fixed sizes, say 64 bytes

How do you know when the end of the application packet is received? This is what I understand but have no confirmation. If you get a packet that is less than 64 bytes, end of sequence. If it is 64 bytes, there is more to come. If the application packet is 64*N where N is an integer, one will receive a 0-byte packet.

This is true for Control packets. How about the data transfers?
