Incorrect endianness during copy since the chip is little endian

This should be copied in reverse since the architecture is little endian

	id[i * 4 + 0] = (uint8_t)(pdwUniqueID[i] >> 0);
	id[i * 4 + 1] = (uint8_t)(pdwUniqueID[i] >> 8);
	id[i * 4 + 2] = (uint8_t)(pdwUniqueID[i] >> 16);
	id[i * 4 + 3] = (uint8_t)(pdwUniqueID[i] >> 24);
