[linux-dvb] Re: Need Help with Siemens DVB-c

Hi,

Things to check:
1) your MAKEDEV script probably made /dev/dvb/adapter[0-3]/*, rather
than /dev/dvb/frontend0. Your frontend programs may be configured to use
the wrong device.
2) Your MAKEDEV script may have created the devices with the wrong
device number. It was recently changed from 250 to 212. I'm not sure
which number the 2.6.8.1 kernel drivers expect it to be, but the
linuxtv.org cvs drivers use 212. Make sure that you get output like the
following:

[ben@dragon adapter0]$ pwd
/dev/dvb/adapter0

[ben@dragon adapter0]$ ls -al
total 8
drwxr-xr-x  2 root root   4096 Sep  2 21:45 .
drwxr-xr-x  6 root root   4096 Sep  2 21:45 ..
crw-------  1 ben  root 212, 1 Sep  2 21:45 audio0
crw-------  1 ben  root 212, 6 Sep  2 21:45 ca0
crw-------  1 ben  root 212, 4 Sep  2 21:45 demux0
crw-------  1 ben  root 212, 5 Sep  2 21:45 dvr0
crw-------  1 ben  root 212, 3 Sep  2 21:45 frontend0
crw-------  1 ben  root 212, 7 Sep  2 21:45 net0
crw-------  1 ben  root 212, 8 Sep  2 21:45 osd0
crw-------  1 ben  root 212, 0 Sep  2 21:45 video0

Finally, having got this setup working recently, I suggest that you
ditch the dvb drivers included in the kernel and just download the dvb
drivers from linuxtv.org's cvs repository. It works for me, whereas the
ones included with the kernel had compile errors.

Good luck!
Ben.
