Problem with SCM/Viaccess CAM

Problem with SCM/Viaccess CAM

[Tomer Barletz]

Hi,
When inserting a SCM/Viaccess CAM, I get the following message:
dvb_ca adapter 0: DVB CAM did not respond :(

According to this:
http://linuxtv.org/hg/v4l-dvb/file/142fd6020df3/linux/Documentation/dvb/ci.txt
this CAM should work.

I'm using kernel 2.6.10.

Any help would be greatly appreciated,
Tomer

SCM CAMs are very slow to start up. I've submitted a patch to work-around this 
issue a few years ago. IIRC, this was around 2.6.14.

So you should upgrade your kernel

Hi Dominique,
I've tried to increase the time-out period from 5 to 10 seconds (as it
is with current source), but with no success.
Did your patch involved any other changes besides this one? How can I
obtain your patch? Did you changed dvb_ca_en50221.c only, or were
there any other files changed?
I know that my kernel is slightly old ;), but it is currently not
feasible for me to upgrade.

Thanks,
Tomer

My patch was just a one line modif to change a #define

You can probably find the patch on dvb mailing archives.
