It was empty....

... until I discoverd that the hardware seem to be initialized fine when it's 
plugged in at boot time.

horus ~ # ll /dev/dvb/

drwxr-xr-x 2 root root 100 14. Okt 14:58 adapter0

horus florian # ll /dev/dvb/adapter0/

crw-rw---- 1 root video 212, 7 14. Okt 14:58 net0

but there seem to be a frontend missing:

horus dvb-t # dvbscan de-Frankfurt
scanning de-Frankfurt
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
main:2232: FATAL: failed to open '/dev/dvb/adapter0/frontend0': 2 No such file 
or directory

Any idea?

Thanks a lot,

Florian
