    摘要： A host process for use in a user-mode device driver architecture is provided by the subject invention. The architecture includes a reflector, a driver manager and the host process which hosts and isolates one or more user-mode device driver(s). The user-mode device driver runs in the user-mode (UM) environment and has access to various UM services. The reflector resides in “kernel memory” (e.g., memory/resource(s) available to operating system) while the driver manager, host process and user mode device driver(s) are located in user space (e.g., memory/resource(s) available to user application(s)). The host process can include a host runtime component and a framework component. The host runtime component is responsible for building a driver stack object, and, locating/loading object(s) of a framework component. The host runtime component further includes a message handler that facilitates communication with the reflector and routes information to components of the host process.

    摘要： 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： A wireless peer-to-peer protocol that supports fast and low power joining to an existing group. The protocol may be an extension of a peer-to-peer protocol that supports a sleep state for a device controlling the group. When a device is seeking to join a group at a time when the controlling device is in a sleep state, another device that has information about the controlling device may provide information to the joining device that may then be used by the joining device to more quickly, and using less power, synchronize with the controlling device. The information may include information about a channel used by the controlling device or about timing of availability of the controlling device. The information may also reveal whether the group provides a service being sought by the joining device or may otherwise influence whether the joining device will attempt to join a group.

    摘要： A system in which wireless devices form a group in accordance with a peer-to-peer protocol and, at a later time, a device may send an invitation request to trigger the devices tore-form the peer-to-peer group. The invitation request may contain an identifier that is associated with a set of a plurality of devices. Those devices may be related such that they perform a function for which a user would want to use those devices together. The group of devices, for example, may be multimedia devices that receive and present streaming multimedia content or may be human interface devices that collectively act as an interface for a work station incorporating a wireless computing device operated by a user. Requesting that remote devices concurrently re-form a group reduces the time and spectral congestion associated with re-forming the group, particularly when the remote devices may periodically enter a low power state.
