problem for reading bytes with I2C on EZ-USB FX

Hello,

I manage to write bytes on a targeted chip on i2c bus from an ez-usb fx. But I did not manage to read the chip using the ez-usb fx.
The targeted chip functions well with my rs232->i2c board.(writing and reading bytes).

Does anyone have manage to do it before?
If so, I would be very pleased to know how.

Thanks a lot.

//lecture i2C
I2CS |= bmSTART;
I2DAT = 0x11;

while ((I2CS & bmDONE)==0) {
}

if ( ((I2CS & bmBERR)==1) || ((I2CS & bmACK)==0)) {
    I2CS |= bmSTOP;
    goto	sortie_ep1;
    }
rien = I2DAT;

for (i=0; i < 0x03  ; i++) {
     while ((I2CS & bmDONE)==0) {
				}

     if ((I2CS & bmBERR)==1) {
	//break;
	I2CS |= bmSTOP;
	goto	sortie_ep1;
      }

      IN1BUF[i] = I2DAT;
      IN1BC = i + 1;
	}

        while ((I2CS & bmDONE)==0) {
	}

	if ((I2CS & bmBERR)==1) {
	I2CS |= bmSTOP;
	goto sortie_ep1;
	}

	I2CS |= bmLASTRD;
	I2CS |= bmSTOP;
	rien = I2DAT;

	} else {
		IN1BUF[0] = 0x30;
		IN1BC = 0x01;
		}

	goto	sortie_ep1;
	}

sortie_ep1:

// Arm the OUT so it can receive the next packet
	OUT1BC = 0;

	// clear the IRQ
	EZUSB_IRQ_CLEAR();
	OUT07IRQ = bmEP1;
