摘要:
A method, apparatus, and computer program product provide applications and application developers with generic access from user mode to the L2CAP layer of Bluetooth by exposing the L2CAP layer to user mode via a socket interface. In particular, a kernel mode primary component and user mode helper component cooperate to expose a Winsock interface to user mode components, and to manage various Bluetooth-specific functions and operations, allowing a user mode user application to access Bluetooth functionality without providing Bluetooth-specific commands or actions, and without being required to use RFCOMM.
摘要:
A method and system for asserting power control over one or more hardware devices connected via a bus. The invention includes a method and system for signaling and waiting to suspend a first device connected to a second device. The invention also includes a method and system for suspending a tree of devices with one or more of the devices hierarchically organized as parent devices and child devices in the tree. A controller at a root of the tree receives an idle request from one or more of the child devices and suspends all devices in the tree after receiving an idle request from each of the child devices. The invention also includes an input/output control (IOCTL) data structure for communicating the idle request.
摘要:
A computer peripheral has a processor, non-volatile memory, and a plurality of controls. The non-volatile memory holds control mappings corresponding to a plurality of application program genres. The control mappings indicate actions to be performed in application programs of particular genres in response to actuation of particular controls. The control mappings indicate controls by unique string indexes that are also used in HID control descriptors associated with the computer peripheral.
摘要:
A computer system that accesses multi-transport devices and associates device instances of the multi-transport device with each other. Devices provide the same device identifier such as a device unique identifier regardless of the transport over which the device is accessed. A visual representation for the multi-transport device may be provided to a user using the device identifier. Also, a single functional representation for the multi-transport device may be provided based on an identifier provided by each function of the device. The functional representation may be independent of the addition and removal of transports and allows abstracting device access via multiple transports from a user and an application. Transports may be selected at an application and/or a system level. Operating characteristics of available transports may be used to select a desired transport, based on transport requirements specified by the application, the user or the system.

In embodiments of extensions for USB driver interface functions, a set of USB driver interfaces are exposed by a USB core driver stack, and the USB driver interfaces include USB driver interface functions to interface with USB client function drivers that correspond to client USB devices. A composite device driver registers itself and requests a function handle for each function of a client USB device. The USB client function drivers are enumerated and the function handles generated for each function of the client USB device. A check first protocol is enforced that directs a USB client function driver to check for availability of a USB driver interface function before interfacing with the USB core driver stack via the USB driver interfaces. A contract version identifier is received that indicates a set of operation rules by which a USB client function driver interfaces with the USB core driver stack.
摘要:
Multi-function devices expose multiple functions to device drivers or other lower-level software. Device function providers can interface with such drivers or lower-level software and can provide information, including device identifiers regarding such functions, to a device display object infrastructure. A device display object can then be created that encompasses one or more functions such that, in one embodiment, the device display object corresponds to a single, physical multi-function device. Alternatively, any combination of functionality from one or more physical devices can be combined into a single device display object representing a virtual multi-function device. Properties of the device display object can be set with reference to user-specified settings, remotely maintained metadata, locally available metadata, and information associated with each function. Functions can be ranked such that, if there is a conflict, information from more highly ranked functions is used to set the properties of the device display object.
摘要:
The present invention relates to systems and methods that facilitate wireless device communications and configuration. A detection component identifies N devices that are coupled together via a biological medium, N being an integer, wherein the medium includes direct or indirect touching to a device or devices. After biological contact, a configuration component initiates a configuration between a subset of the devices. Although configurations and/or other communications can be conducted through a medium such as the human body, the present invention can employ an initial touch to identify respective devices whereby other electronic configuration sequences commence without further device contact. Other aspects include chain touching between users and/or devices to facilitate contact between the devices. Location detection components can also be provided to identify when users are present near a device, the detected presence to commence further automated procedures, and/or the location detection components can enable devices to identify other devices in a crowded wireless environment.
摘要:
A technique to simplify L2CAP channel creation/configuration for a node is presented. The method enables a node to determine how involved it is in the L2CAP channel connection creation and management process. There are three levels of participation that the node may specify. The three levels are no involvement at all, minimal involvement, and total involvement. In no involvement, the channel is dropped if a remote node does not accept all node specified parameters. In minimal involvement, the channel is dropped if a remote node does not accept all node specified parameters and the node is notified when the connection has been disconnected by a remote disconnect or HCI link loss. In the total involvement level, the node is fully involved in the channel creation/configuration. The node provides a function pointer that is called to confirm or reject parameters. If a parameter is unacceptable, the connection is disconnected.
