This isn't really a fix, I think i mentioned this on the ML ages ago,

Argh, I just replied that same. Oliver, do you has that same device? Is
it working? Could you tweak to see if I2C readings are working at all?
I have the same device, but mine works normally (though I haven't
checked for ages), I will try it tonight when I'm at home and don't
forget what happens with my current kernel.

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.

Antti
