    • Bidirectional (bidi) extension techniques for USB and/or other similar busses/connections are described in which an interface is provided to enable bidirectional communication with connected devices. The interface may be implemented as an operating system component to handle bidi communication for devices from multiple different independent hardware vendors (IHVs). Device drivers for different devices can be configured to include extension files in accordance with an established schema for bidi communication. The extension files describe supported bidi attributes, capabilities of the device, and how to make calls into the device. The interface operates to detect the extension files and set-up a corresponding device for bidi communication. Applications then interact through the interface to access, retrieve, and set configuration and status data for connected devices. The use of extension files enable creation of architecture independent devices drivers that can be used across different platforms with substantially no changes.
    • 描述了用于USB和/或其他类似总线/连接的双向(双向)扩展技术,其中提供接口以实现与所连接设备的双向通信。 该接口可以被实现为操作系统组件,以处理来自多个不同的独立硬件供应商(IHV)的设备的双向通信。 可以将不同设备的设备驱动程序配置为根据建立的双向通信模式来包括扩展文件。 扩展文件描述支持的bidi属性,设备的功能以及如何拨打设备。 该接口用于检测扩展文件并设置相应的设备进行双向通信。 应用程序然后通过接口进行交互以访问,检索和设置连接的设备的配置和状态数据。 使用扩展文件可以创建独立于架构的设备驱动程序,可以在不同平台上使用,基本上没有任何变化。
