Abstract
A port device for use in a USB extension environment that couples a host device to one or more USB devices is provided. The port device includes a USB physical layer interface configured to be coupled to a USB device, a host device, or a USB hub device; a remote interface configured to be coupled to an extension medium; and an endpoint table. The port device includes logic that, in response to execution by the port device, causes the port device to perform actions comprising: receiving a first USB message addressed to a first endpoint; in response to determining that the endpoint table indicates that the first endpoint is active, providing the first USB message for transmission to the first endpoint; and in response to determining that the endpoint table indicates that the first endpoint is inactive, providing a synthetic USB message for transmission to the host device.
