The driver has to tune to the intermediate frequency 
that's output by the LNB. (There is a local oscillator+downmixer in there...)

This is what the one here has

info = {
      name = "ST STV0299 DVB-S", '\000' <repeats 111 times>, type = FE_QPSK, 
      frequency_min = 950000, frequency_max = 2150000, 
      frequency_stepsize = 125, frequency_tolerance = 0, 
      symbol_rate_min = 1000000, symbol_rate_max = 45000000, 
      symbol_rate_tolerance = 500, notifier_delay = 0, 
      caps = (FE_CAN_INVERSION_AUTO | FE_CAN_FEC_1_2 | FE_CAN_FEC_2_3 | FE_CAN_FEC_3_4 | FE_CAN_FEC_5_6 | FE_CAN_FEC_7_8 | FE_CAN_FEC_AUTO | FE_CAN_QPSK)}, 

Frequency_min and max match yours. 

Try a different scan tool, and make sure you get a signal out of your LNB. 
Proper DISH ALIGNMENT is important, 
and don't forget a grounding bloc.
