[Bug 448811] Re: [Karmic] DiBcom an2235 DVB tuner not working after Karmic upgrade

[Rocci]

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 ?

As you can see w_scan is happy now the /dev directory structure is corrected.
