Abstract: A USB test device is disclosed comprising an input/output (I/O) subsystem to capture communication between a host and a peripheral device communicating via at least on USB cable. A processor subsystem analyzes the captured communication and determines if a communication failure occurred and if the host or peripheral device caused the communication failure. The tester can also be part of a computer system that comprises at least one universal serial bus (USB), a host computer and a peripheral device. The host computer and the peripheral device communicate over the at least one USB. A test device is connected to the at least one USB to capture USB communications between the host computer and the peripheral device. The test device analyzes a captured communication, determines if a USB communication failure occurred, and determines whether the host computer or the peripheral device caused the USB communication failure. A method for testing communications over a USB is also disclosed.

Abstract: The present disclosure relates to an appliance configured for connection to a network and communication with a device connected to the network. In one embodiment, the appliance comprises a processing device configured to control operation of the appliance, memory including logic configured to receive software that facilitates communication between the appliance and the device from a software source, and network interface devices with which the appliance communicates with the software source.
