ATMega wrong function argument

I am writting firmware for AT90CAN32 using AVR Studio + WinAVR. It seems simple for experienced AVR programmers. I pass int argument to function, but inside the function it is always zero. There is inside protocol.c file:

#include <uart.h>

static char packet[16] =  ":AA111122223!f\r\n";

void vDivRequesting(void)
{
    uint8_t cntOfBms = getCountOfBms( );
    for(uint8_t i=0; i<cntOfBms; i++)
    {
        createPacket(getBmsNetworkNumber(i), REQUEST_V_DIV, 1);
        usartSendString(packet,11);
        _delay_ms(200);
    }
}

There is uart.c file:

void usartSendString( char *data, uint8_t len )
{
    uint8_t i=0;
    usartSendByte(len + 0x30);
    for( i=0; i<len; i++)
    {
       usartSendByte(*data);
       *data++;
    }
}

And it prints me that len argument is zero. usartSendString function is defined in uart.h file. What is wrong with that code?
