I am attempting to learn USB with PSOC and have built one of the examaple designs.  It is a simple USB echo program as folows:

#include <device.h>

uint8 Count;
uint8 Buffer[128];
void main()
{
    /* Initialization Code: */
    CYGlobalIntEnable;    
    USBUART_1_Start(0, USBUART_1_3V_OPERATION);
    while(!USBUART_1_bGetConfiguration());
    USBUART_1_Init();
   
    /* Main Loop: */
    for(;;)
    {
        Count = USBUART_1_bGetRxCount();
        if(Count != 0)                            /* Check for input data from PC */
        {
            USBUART_1_ReadAll(Buffer);
            USBUART_1_Write(Buffer, Count);        /* Echo data back to PC */
            while(!USBUART_1_bTxIsReady()){}        /* Wait for Tx to finish */
        }
    }
}

I get the following warnings and errors:

WARNING: C:\DOCUMENTS AND SETTINGS\BUN\MY DOCUMENTS\PSOC CREATOR\DESIGN04\DESIGN04.CYDSN\MAIN.C:23: 'USBUART_1_Init': missing function-prototype
WARNING: C:\DOCUMENTS AND SETTINGS\BUN\MY DOCUMENTS\PSOC CREATOR\DESIGN04\DESIGN04.CYDSN\MAIN.C:28: 'USBUART_1_bGetRxCount': missing function-prototype

ERROR: C:\DOCUMENTS AND SETTINGS\BUN\MY DOCUMENTS\PSOC CREATOR\DESIGN04\DESIGN04.CYDSN\MAIN.C:31: 'USBUART_1_ReadAll': requires ANSI-style prototype

If I look in the USBUART_1.h I do not see these prototypes.  Should I be including some other .h file or something??
