摘要：
There is provided a method of communicating diagnostic information between a Universal Serial Bus (USB) host and a USB device, the USB host including a host USB controller, a main driver and a host main application. The method comprises establishing a data pipe in a data class interface between the USB host and the USB device for data communication; establishing a diagnostic information pipe in the data class interface between the USB host and the USB device for diagnostic information communication; monitoring the data class interface between the host USB controller and the main driver using a filter driver; intercepting the diagnostic information in the diagnostic information pipe of the data class interface using the filter driver; directing the diagnostic information intercepted by the filter driver to a host diagnostics application; and directing the data in the data pipe of the data class interface to the main driver.
