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.

Soft disconnect and reconnect for USB tunneled path

A method includes detecting a communication event over a communication buscoupled to a device, and in response to detecting the communication event, deactivating a module of the device. The method may further include sending a data throttle packet over the communication buswhile the deactivated module reactivates.

Power gated communication controller

An interface for low power, high bandwidth communications between units in a device in provided herein. The interface comprises a USB 3.0 system interface and a SuperSpeed inter-chip (SSIC) protocol adaptor configured to facilitate communications between the USB 3.0 system interface and an M-PHY interface.
