Abstract: A method for reconfiguring a bus device from a first configuration into a second configuration, wherein the second configuration is not visible to, and is not selectable by, an unauthorized host device that connects to the bus device through a peripheral port of the bus device is described. In the bus device, a received message transmitted by the authorized host device through the peripheral port of the bus device to which the authorized host device is connected is parsed and an instruction to reconfigure the bus device from the first configuration into the second configuration is detected. Responsive to detecting the instruction, a daemon signals reconfiguration of the bus device into the second configuration, and responsive to the daemon signaling, the bus device is reconfigured into the second configuration. Other embodiments are also described.
