Aspects disclosed in the detailed description include power saving techniques in computing devices. In particular, as data is received by a modem processor in a computing device, the data is held until the expiration of a modem timer. The data is then passed to an application processor in the computing device over a peripheral component interconnect express (PCIe) interconnectivity bus. On receipt of the data from the modem processor, the application processor sends data held by the application processor to the modem processor over the PCIe interconnectivity bus. The application processor also has an uplink timer. If no data is received from the modem processor before expiration of the uplink timer, the application processor sends any collected data to the modem processor at expiration of the uplink timer. However, if data is received from the modem processor, the uplink timer is reset.

In some embodiments, systems, devices, and methods are provided that allow a host device to communicate video information, network information, and USB information over USB via a USB host controller. The video information and the network information are encapsulated within USB and communicated by the USB host controller.

In some embodiments, the USB information communicated by the USB host controller is further communicated over a non-USB extension medium by an upstream facing port device and one or more downstream facing port devices.

The present disclosure relates to a system and method for enabling implementation of a secondary function of a universal serial bus (USB) device on a computer that the USB device is communicating with, wherein an operating system of the computer does not have a required driver which needs to be mapped to the USB device to enable implementation of the secondary function. The system involves a USB device which has the required driver for implementing the secondary function stored therein. The required driver can be supplied to the computer from the USB device using a control which selects the secondary function of the USB device.

An information processing apparatus includes: an operating unit capable of recognizing a peripheral apparatus. The operating unit includes: a first recognizing unit configured to recognize, when a peripheral apparatus is connected to the operating unit and identification information about the connected peripheral apparatus is included in peripheral apparatus information including predetermined identification information, the connected peripheral apparatus as a first peripheral apparatus; and a second recognizing unit configured to recognize, when a peripheral apparatus is connected to the operating unit and the identification information about the connected peripheral apparatus is not included in the peripheral apparatus information, the connected peripheral apparatus as a second peripheral apparatus.

Example implementations relate to peripheral device operation. For example, a peripheral device may include a processor. The processor may detect that a computing device is in communication with the peripheral device and send peripheral device information to the computing device. The peripheral device information may specify characteristics associated with the peripheral device including a purpose, capability, and context of the peripheral device. The processor may receive operational data from the computing device, where the operational data may be based on the peripheral device information and may indicate a manner of operating the peripheral device. The processor may perform an operation based on the operational data.

Disclosed is a mobile device which comprises a CPU, a USB Type-C interface and a switching circuit. The switching circuit is configured to switch a connection line of two preset pins of the USB Type-C interface to connect UART TxD and UART RxD pins of the CPU, upon detecting that a UART cable is inserted into the USB Type-C interface.

In some embodiments, a system is provided for communicating USB information via an extension medium. The system comprises an upstream facing port device (UFP device) and a downstream facing port device (DFP device). The UFP device and the DFP device are communicatively coupled via a non-USB extension medium, and allow a host device communicatively coupled to the UFP device and a USB device communicatively coupled to the DFP device to communicate via USB-compliant techniques. In some embodiments, the DFP device generates synthetic request packets to request additional data packets from the USB device compared to those requested by the host device. In some embodiments, the DFP device is configured to store a request packet in a packet queue if the request packet is received from the UFP device while the DFP device is busy receiving a response to a previous synthetic request packet from the USB device.

An adapter device communicates with a sink device and a source device using first and second communication schemes, respectively. The adapter device includes: a transceiver receiving a state read request by detecting that a serial data line connected between the adapter device and the sink device is driven to a low level when a serial clock line connected therebetween is at a high level, and drive the serial data line to the low level and drive the serial clock line to a low level; a transmitter transmitting the state read request to the source device after the serial clock line is driven to the low level; and a receiver receiving a state read signal to read data of a state register in the sink device from the source device, wherein the transceiver transmits the state read signal to the sink device via the serial data line.

An aspect of obtaining optical signal health data in a SAN includes receiving, by a computer processor, a request for data corresponding to current operational characteristics of elements of a storage area network to which a host system computer has access. A further aspect includes instantiating, by the computer processor, a virtual host bus adapter interface on the host system computer, transmitting, via the virtual host bus adapter interface, the request to the elements in the portion of the storage area network, aggregating data received from each of the elements, and displaying the aggregated data via the computer processor.
