Abstract
A method of operating a Universal Serial Bus (USB) host system includes: disabling, by a USB host driver of the USB host system, a first tunneled path between a first port of a USB host controller of the USB host system and a first port of a USB device controller of a USB device, where the first tunneled path is configured to, through protocol tunneling, transmit first data packets of a first protocol format; sending, by the USB host driver, a request for protocol switching to a connection manager of the USB host system; disconnecting, by the connection manager, the first tunneled path; and establishing, by the connection manager, a second tunneled path between a second port of the USB host controller and a second port of the USB device controller.
