This control code requests the HID class driver to poll a device for status.
Parameters
Remarks
This I/O control code is not strictly necessary for the Windows CE HID class driver, because USB device status is collected automatically by the USB host controller driver (HCD). This I/O control code is defined in Windows CE only for compatibility with Windows NT. Processing for this code can simply return success without doing any work.
