Abstract
A Universal Serial Bus (USB) device uses a same elasticity buffer for buffering packets for multiple different ports and only necessary packet detection circuitry is associated with the individual ports. A collision detection circuit is further included corresponding with information received from the packet detection circuitry. This simplified universal elasticity buffer architecture reduces the complexity and cost of the USB device.
