  [in] UDECXUSBDEVICE                    UdecxUsbDevice,
  [in] PUDECX_USB_DEVICE_PLUG_IN_OPTIONS Options
);

Parameters

[in] UdecxUsbDevice

A handle to UDE device object. The client driver retrieved this pointer in the previous call to UdecxUsbDeviceCreate.

[in] Options

A UDECX_USB_DEVICE_PLUG_IN_OPTIONS-type value that indicates the port to which the device is plugged. At most one of Usb20PortNumber, Usb30PortNumber can be non-zero. NULL disables plug-in options (use defaults).

The method returns STATUS_SUCCESS if the operation succeeds. Otherwise, this method might return an appropriate NTSTATUS error code.

Remarks

After the client driver calls this method, the class extension sends I/O requests and invokes callback functions on the endpoints and the device.
