I really need help with my SPI devices and arduino mega 2560

I am having trouble initializing my 3 SPI devices, a micro sd card module, usb host shield and RA8875.

The connection is sd_cs 4, RA8875_cs 5 and usb_cs 10. Here is my setup function.

void setup()

{

Serial.begin(9600);

pinMode(10,OUTPUT);

digitalWrite(10, HIGH);

pinMode(5,OUTPUT);

digitalWrite(5, HIGH);

pinMode(4, OUTPUT);

digitalWrite(4, HIGH);

digitalWrite(5, LOW);

Serial.println(“RA8875 start”);

//RA8875 initialize

if (!tft.begin(RA8875_800x480)) {

Serial.println(“RA8875 Not Found!”);

while (1);

}

Serial.println(“Found RA8875”);

//sd card initialize

digitalWrite(4, LOW);

if (!SD.begin(4)) {

Serial.println(“SD initialization failed!”);

return;

}

Serial.println(“SD initialization done.”);

digitalWrite(4, HIGH);

//usb initialize

digitalWrite(10,LOW);

delay(20);

digitalWrite(10,HIGH);

#if !defined(MIPSEL)

while (!Serial); // Wait for serial port to connect - used on Leonardo, Teensy and other boards with built-in USB CDC serial connection

#endif

Serial.println(“Start USB”);

if (Usb.Init() == -1)

Serial.println(“OSC did not start.”);

else

Serial.println(“USB ready!”);

digitalWrite(10,HIGH);

delay( 200 );

}

the ra8875 and sd card are fine but the usb host have an output "OSC did not start’’

I really need help please :frowning:
