Patent attributes
A circuit interfaced between a first USB host and a second USB host for providing unidirectional transmission of data signals from the first USB host to the second USB host is provided. A first converter circuit is operable to receive data signals from the first USB host and convert them from a USB protocol to a second communications protocol. A second converter circuit is operable to receive the converted data signals from the first converter circuit and convert them from the second communications protocol to the USB protocol for transmission to the second USB host. The first and second converter circuits are electrically connected to each other in such a manner as to provide a transmission path from the first USB host to the second USB host and to disable a transmission path from the second USB host to the first USB host.
