Same problem here.
Using Karmic AMD64.
Winfast DVR3200H using the CX88 module.
Initially there were only /dev/dvb0.demux0 /dev/dvb0.dvr0 /dev/dvb0.frontend0
/dev/dvb0.net0
I also created the /dev/dvb/adapter0 directory with the symlinks in it and
found w_scan would then scan channels successfully.
This is not a hardware issue.
Possibly broken udev scripts ?
