LPC1768 usbDeviceError

[ali_asadzadeh]

Hi
I have made a simple program for my LPC1768 using keil V5.22 the LPC should act like a USB host to a mice that I have attached to it. the problem is that I will always got the usbDeviceError from the USBH_HID_GetDeviceStatus function.
 
Here is my USB thread code

Code: [Select]

void USB_Thread (void const *arg)
{
     static usbStatus myst;
     static      usbHID_MouseState mymouse;
     myst=USBH_Initialize (0);                       /* Initialize USB Host 0         */
     
  while (1)
     {
            osDelay(10);
         myst=USBH_HID_GetDeviceStatus(0);
     }

}

and this is my main function

Code: [Select]

osThreadDef(USB_Thread,  osPriorityNormal, 1, 2048);
osThreadId tsk_USB;

int main (void) {
        osKernelInitialize ();                    // initialize CMSIS-RTOS
        osKernelStart ();                         // start thread execution
        tsk_USB = osThreadCreate(osThread(USB_Thread),  NULL);  //it's used for USB mouse
     while(1)
     {
     }
}


Here are some pictures of my RTX and USB configuration boxes
Do you have any Idea?
