Hello,

There is a regression regarding this DVB-C card from the subject, which as it looks is not very new, but nobody noticed the problem. After bisecting I've found the commit which is responsible for this problem - that the card is not detected.
By the way mercurial bisect was not very useful because some commits does not compile or load, so I had to "simulate" bisecting.

Bad version:

The changeset 7484:0b82bb67fb80 is rather big, but I'm just guessing that removing/integrating of this file with other flexcop files is the cause:

linux/drivers/media/dvb/b2c2/stv0297_cs2.c

Kernel version 2.6.23. Currently can't test with newer kernel on this computer.
I can give more info if needed.

Hi Boyan,

did you try the latest hg from linuxtv.org recently?

A patch was provided fixing the cablestar support.

Can you please try it ?

regards,
Patrick.

Hi Patrick,

Thanks for asking.
It's been long time and I've missed the fix in hg. The card is now detected. Thanks!
