I wanted to know what is the reason that different versions of USB have different speed though they more or less follow the same protocol(by protocol i mean that they have effectively same overhead). For example in the case of full speed and high speed USB max data that can be transmitted in a frame are 1023 and 1024 respectively but they have a considerable difference in their speed(which are 12 Mbps and 480 mbps respectively). Can you also please tell me the reason for the dramatic increase in speed of super speed USB.
