Abstract: In one or more embodiments, methods and apparatus are provided for simulating device communications such as those of the Universal Serial Bus (“USB”) or the like. The methods and apparatus involve receiving host requests that represent commands in a communication protocol and are associated with communication endpoints, distributing the host requests across the communication endpoints in the order that they are received, to their associated endpoints to generate a distribution of requests, generating a reordered plurality of host requests by selecting the host requests from the communication endpoints in an order based upon the order in which the requests are received and one or more simulation factors, receiving device requests from a simulated device in accordance with the communication protocol, merging the reordered host requests and the plurality of device requests to form a merged sequence of requests, and performing commands from the merged sequence of requests in the order.
