	Hello,

	I'm trying to configure an AverTV Hybrid Express card. I've probably
done a mistake...

Distribution : Linux Debian lenny (kernel 2.6.26 from kernel.org).

cauchy:[/etc/modprobe.d] > lspci
...
02:00.0 Multimedia video controller: Conexant Device 8852 (rev 02)

         Kernel driver in use: cx23885
         Kernel modules: cx23885
...

	I have seen that this card should work with cx23885.
 From dmesg :

CORE cx23885[0]: subsystem: 1461:c039, board: DViCO FusionHDTV5 Express

	I have to add card=4 option. With all others card, dvb devices are not
created. Card seems to be usable :
Root cauchy:[/sys/class/dvb] > ls -al

drwxr-xr-x  6 root root 0 jui 21 19:24 .

/dev/dvb/adapter0/dvr0    /dev/dvb/adapter0/net0
Root cauchy:[/sys/class/dvb] >

	But I'm not able to continue...

Root cauchy:[~] > dvbscan -out raw test /usr/share/dvb/dvb-t/fr-Paris

	This last command does not crash, but does nothing...

  1599 root      20   0 14092  492  368 R  100  0.0  28:16.61 dvbscan


	Where's my mistake ?

	Regards,

	JKB
