wifi shield not present!!

Hey guys!

I am in trouble with connecting a wifi shield(CC3000, which doesn’t have a usb port, that is, only can be used by connecting with the Arduino) with Arduino R3. (You can see the pictures of them.)

After I connected it with the Arduino perfectly, I tried a few source codes such as driver patch 1_11 and buildtest from adafruit CC 3000 library.

But it said that ‘initializing CC3000…’ from both ‘buildtest’ and ‘driver patch’. And nothing happened.
I included ‘buildtest’ FYI.

Any thoughts?

Thank you for your help in advance!

p.s. I tried to install a firmware to the wifi shield, but I couldn’t do that for it said that ‘wifi shield not present’. Moreover, CC3000 doesn’t have a usb port as well. This is my second problem…

Here’s ‘buildtest’ source code.

#include <Adafruit_CC3000.h>
#include <ccspi.h>
#include <SPI.h>
#include <string.h>
#include "utility/debug.h"

// These are the interrupt and control pins
#define ADAFRUIT_CC3000_IRQ   3  // MUST be an interrupt pin!
// These can be any two pins
#define ADAFRUIT_CC3000_VBAT  5
#define ADAFRUIT_CC3000_CS    10
// Use hardware SPI for the remaining pins
// On an UNO, SCK = 13, MISO = 12, and MOSI = 11
Adafruit_CC3000 cc3000 = Adafruit_CC3000(ADAFRUIT_CC3000_CS, ADAFRUIT_CC3000_IRQ, ADAFRUIT_CC3000_VBAT,
                                         SPI_CLOCK_DIVIDER); // you can change this clock speed but DI

#define WLAN_SSID       "myNetwork"        // cannot be longer than 32 characters!
#define WLAN_PASS       "myPassword"
// Security can be WLAN_SEC_UNSEC, WLAN_SEC_WEP, WLAN_SEC_WPA or WLAN_SEC_WPA2
#define WLAN_SECURITY   WLAN_SEC_WPA2
