Hi there,
i just bought a TechniSat Skystar2 TV PCI DVB-S card because it seems to 
be well supported under Linux. Unfortunately, i can't use the card under 
Linux. I use Debian Sarge, Kernel on my PC. As soon as try 
to set the channel (using szap) i get an error message, that the 
frontend could not be accessed. The exact error message from szap is:

./szap -c /home/repplix/pub/channels.conf -n 1
reading channels from file '/home/repplix/pub/channels.conf'
zapping to 1 'Sat.1':
sat 0, frequency = 12480 MHz V, symbolrate 27500000, vpid = 0x06ff, apid 
= 0x0700
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
opening frontend failed: No such file or directory

If i enter lsmod, it seems that all required modules can be loaded:
skystar2               28356  0
dvb_core               78536  1 skystar2
mt352                   5636  1 skystar2
stv0299                 9924  1 skystar2
nxt2002                 8900  1 skystar2
mt312                   7876  1 skystar2

But if i start 'dmsg' i found the following error messages:
 kernel: drivers/media/dvb/b2c2/skystar2.c: FlexCopIIB(rev.195) chip found
 kernel: drivers/media/dvb/b2c2/skystar2.c: the chip has 38 hardware filters
 kernel: DVB: registering new adapter (SkyStar2).
 kernel: i2c_readbytes: i2c read error (addr 0a, err == -121)
 kernel: skystar2: A frontend driver was not found for device 13d0/2103 
subsystem 13d0/2103

I found a discussion about a similar problem on this list 
http://www.linuxtv.org/mailinglists/linux-dvb/2004/12-2004/msg00307.html and

Here, the solution was to install a patch for kernel 2.6.10. Since i use 
2.6.11 this patch should already
be included in this kernel version.

It would be great if somebody can send me suggestions how to solve this 

Best regards
