	 * If this option is set then the USBIO driver generates a USB device reset
	 * after the last handle for a device has been closed by the application.
	 * If this option is active then the USBIO_UNCONFIGURE_ON_CLOSE flag will be
	 * ignored.
	 * <br>
	 * The default state of this option is defined by the registry parameter ResetDeviceOnClose.
	 * <li> USBIO_UNCONFIGURE_ON_CLOSE -
	 * If this option is set then the USBIO driver sets the USB device to its
	 * unconfigured state after the last handle for the device has been closed by the application.
	 * <br>
	 * The default state of this option is defined by the registry parameter UnconfigureOnClose.
	 * <li> USBIO_ENABLE_REMOTE_WAKEUP -
	 * If this option is set and the USB device supports the Remote Wakeup feature the USBIO driver
	 * will support Remote Wakeup for the operating system.
	 * That means the USB device is able to awake the system from a sleep state.
	 * The Remote Wakeup feature is defined by the USB 1.1 specification.
	 * <br>
	 * The Remote Wakeup feature requires that the device is opened by an application
	 * and that a USB configuration is set (device is configured).
	 * <br>
	 * The default state of this option is defined by the registry parameter EnableRemoteWakeup.
