Sorry, I provided very little information. Here is what I did:

   - downloaded linuxtv-dvb-1.0.0-pre3.tar.gz
   - did a cd to driver to compile and a make insmod which produced the
     following messages in /var/log/messages:

      Jun 13 15:44:21 dwdsat2 kernel: Linux video capture interface: v1.00
      Jun 13 15:44:21 dwdsat2 kernel: DVB: registering new adapter (KNC1 DVB-S).

   - compiled apps/szap
   - created /root/.szap/channels.conf with one entry
   - started szap as follows: ./szap -n 1

      sat 0, frequency = 11096 MHz H, symbolrate 27000, vpid = 0x0000, apid = 0x0000
      using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
      opening frontend failed: No such device

I am trying this with a plain kernel.org kernel 2.4.21 under RedHat 9 with
the following hardware:
