DVB: Firmware loads, what's next

Hello, when I plug in my dvb-t box I get this syslog messages:

Oct 14 11:05:15 horus usb 1-3: new high speed USB device using ehcihcd and address 8 Oct 14 11:05:15 horus usb 1-3: configuration #1 chosen from 1 choice Oct 14 11:05:15 horus dvb-usb: found a 'AVerMedia AverTV DVB-T USB 2.0 (A800)' in cold state, will try to load a firmware Oct 14 11:05:15 horus dvb-usb: downloading firmware from file 'dvb-usb-avertv-a800-02.fw'

Looks ok to me. These are the modules I have loaded:

horus dvb-t # lsmod Module Size Used by videodev 6592 0 dvbusba800 4292 0 dvbusbdibusbcommon 5380 1 dvbusba800 dib3000mc 11392 1 dvbusbdibusbcommon dib3000common 1792 1 dib3000mc dvbusb 13896 2 dvbusba800,dvbusbdibusbcommon dvbcore 61224 1 dvbusb i2ccore 14672 2 dib3000common,dvbusb dvbpll 9988 2 dvbusbdibusbcommon,dvbusb

Stripped some, which are IMO not DVB relevant.

But when I try to scan:

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

What's missing at my config? kernel options?

Thanks,

Florian
