Actually, I has RTL2832U + FC2580, and it works. It is not Asus 
U3100Mini Plus.

Reading of that chip id must be working on the very first, is RTL2832U 
driver detects whole tuner by probing it.

	/* check FC2580 ID register; reg=01 val=56 */
	ret = rtl28xxu_ctrl_msg(d, &req_fc2580);
	if (ret == 0 && buf[0] == 0x56) {
		priv->tuner = TUNER_RTL2832_FC2580;
		priv->tuner_name = "FC2580";
		goto found;
	}

So I wonder if tuner I2C readings starts failing after that.
