I have a problem with a KNC1 DVB-C card, first was not recognized by the system, and on a lspci -vv reported : 

00:0b.0 Multimedia controller: Philips Semiconductors SAA7146 (rev 01)
        Subsystem: KNC One: Unknown device 0022
        Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B-
        Status: Cap- 66Mhz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR-
        Latency: 64 (3750ns min, 9500ns max)
        Interrupt: pin A routed to IRQ 11
        Region 0: Memory at fae00000 (32-bit, non-prefetchable) [size=512]

Then I defined susbsystem 22 in budget-av.c, and the board appeared in /dev/dvb. Unfortunately, the result on scandvb is still the same: 

using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
initial transponder 306000000 6900000 0 3
>>> tune to: 306000000:INVERSION_AUTO:6900000:FEC_NONE:QAM_64
WARNING: >>> tuning failed!!!
>>> tune to: 306000000:INVERSION_AUTO:6900000:FEC_NONE:QAM_64 (tuning failed)
WARNING: >>> tuning failed!!!

Signal presence was tested before.

What have i done wrong?
