Or maybe you take a picture of tuner can without cover. Also close look picture of card would be nice. Though definately demod is stv0299, but tuner chip may be different. I suspect it is stb6000, but such combination(stb6000 + stv0299) not supported in the driver now. Anyway, you can try modprobe dm1105 with parameter card=1 from s2-liplianin tree.
