[linux-dvb] Frontend for skystar2 (Technisat Airstar 2 DVB-T)?

[Christoph Peus <cp@peus.net>]

Hi everybody,

I'm trying to make my new Technisat Airstar 2 work under Gentoo Linux - 
without success yet.

What I have done so far:
========================

- kernel 2.6.9 (vanilla)
- modprobe skystar2 works fine -> dvb_core and skystar2 modules loaded
- compiled linuxtv-dvb-apps-1.1.0
- made an initial-tuning-data-file, based on soemthing stolen from the net:

# DVB-T Ruhrgebiet
# T freq bw fec_hi fec_lo mod transmission-mode guard-interval hierarchy
T 538000000 8MHz 2/3 NONE QAM16 8k 1/4 NONE
T 586000000 8MHz 2/3 NONE QAM16 8k 1/4 NONE
T 746000000 8MHz 2/3 NONE QAM16 8k 1/4 NONE
T 818000000 8MHz 2/3 NONE QAM16 8k 1/4 NONE
T 834000000 8MHz 2/3 NONE QAM16 8k 1/4 NONE

- scan de-Ruhrgebiet yields:
scanning de-Ruhrgebiet
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
main:1882: FATAL: failed to open '/dev/dvb/adapter0/frontend0': 2 No 
such file or directory

- noticed that I missed the frontend modules in the kernel configuration
- compiled and installed all frontend modules, hoping that the kernel's 
configuration help text is rigth, which says: "If you don't know what 
tuner module is soldered on your DVB adapter simply enable all supported 
frontends, the right one will get autodetected."


Questions:
==========

How should this autodetection of the correct frontend work? (It does not 
seem to work for me!?)

How to find out the correct frontend when autodetection doesn't work?

Why is /dev/dvb/adapter0/frontend0 missing in my devfs? (Will this 
appear when the correct frontend module is loaded?)


Thanks for reading (and answering ;-)
