Abstract
A system for allowing a designer to implement Universal Serial Bus (USB) 2.0 in topologies not anticipated by a USB 2.0 specification and with reduced channel losses, the system comprising: a bus channel having a plurality of electrical elements; and a boost circuit connected at a predetermined location on the bus channel; a plurality of USB signals transmitted through the system; wherein edges of the plurality of USB signals are boosted without impacting the bi-directional nature of the bus channel.

A system for allowing a designer to implement Universal Serial Bus (USB) 2.0 in topologies not anticipated by a USB 2.0 specification and with reduced channel losses, the system comprising:
- a bus channel having a plurality of electrical elements;
- and
- a boost circuit connected at a predetermined location on the bus channel;
- wherein the boost circuit is configured so as to boost edges of a plurality of USB signals transmitted through the system without impacting the bi-directional nature of the bus channel.
A method for allowing a designer to implement Universal Serial Bus (USB) 2.0 in topologies not anticipated by a USB 2.0 specification, the method comprising:
- a bus channel having a plurality of electrical elements and a boost circuit connected at a predetermined location on the bus channel in order to reduce channel losses by implementing the steps of:
- transmitting through the system a plurality of USB signals;
- and
- minimizing path delays and hub hops;
- wherein edges of the plurality of USB signals are boosted without impacting the bi-directional nature of the bus channel.
