Abstract:
An interface, for serial data communication between a host and a connected peripheral during a session, comprising: contacts including a power signal contact for supplying power from the connected host to the connected peripheral and at least one data signal contact for serially communicating data between the connected host and connected peripheral; and means configured to periodically check the connection between host and peripheral comprising: transmission means configured to repeatedly send a poll signal via the power signal contact; and reception means configured to receive a reply signal via one of the contacts
Abstract:
An audio system sets a signal line path between the medium of an audio device and an external device and uploads a digital audio file from the external device to the audio device according to a user's manipulation of the audio. In addition, a communication system selectively uses USB and UART communications by commonly using a single USB connector and connects a connector of an external device and an audio/USB/UART common connector through a single cable, so that audio/USB or audio/UART signals are selectively outputted through a common audio signal line. Accordingly, the audio system can interface with various kinds of external devices without external modification or additional installation of a dedicated interface in the audio device with a USB connector. In addition, the USB/UART common communication system can commonly use the USB connector without regard to USB and UART connection signals and can selectively output the audio/USB or audio/UART signals through the single cable in the audio device.
Abstract:
A communication device has a process unit, a network interface, a communication interface, an interface control unit, a device control unit, and a relay unit. The network interface communicates with a terminal device connected to a network. The communication interface communicates with a locally connected peripheral device. The interface control unit controls the communication interface and transmits control data to the peripheral device, the control data being for controlling the peripheral device. The device control unit generates the control data for the peripheral device in accordance with an instruction entered from the processing unit, and transmits the control data to the interface control unit. The relay unit extracts the control data for the peripheral device from a packet received by the network interface, and transmits the control data to the interface control unit.

Abstract:
A method for obtaining a quorum vote by a first node using a Universal Serial Bus (USB) quorum cable (121), wherein the USB quorum cable (121) comprises a first end (123) connected to a first node (100) and a second end (125) connected to a second node (102), including determining whether the USB quorum cable (121) is reserved by the second node (102) by querying a memory (126) located in the USB quorum cable (121), if the USB quorum cable (121) is not reserved by the second node (102) attempting to reserve the USB quorum cable (121), determining whether the attempt to reserve the USB quorum cable (121) was successful, and obtaining the quorum vote by the first node (100), if the attempt to reserve the USB quorum cable (121) is successful.
Abstract:
In an electronic device having a USB controller capable of transferring data in a High-Speed mode for transferring data at a first transfer rate and in a Full-Speed mode for transferring data at a rate lower than the first transfer rate, whether the connection mode is the High-Speed mode or the Full-Speed mode is acquired when a USB cable is connected. The first or second configuration conforming to the acquired mode is selected, the USB controller is controlled based upon the selected first or second configuration, and processing for transferring data to a connected external device is executed. This makes it possible to execute data transfer processing that is suited to the connection mode.
