Sorry but that is a no go for me.. It is in production now and my 
boss(AKA Wife) would do some unspeakable to me if I do anything that 
interrupts her favourite shows. Just kidding about the last part but not 
about running on windows. Sorry.

I will do my best if you or anyone else need any debugging done and/or 
testing of patches that I can use when compiling media_build.

I did some more testing today and it seems that my media_build 
environment was in a funky state. Will try to take some time and install 
latest and greatest not that I'm very optimistic. Mauro did some work 
lately on the driver but he said it shouldn't have anything to do about 
this problem and the commit messages seems to be about something 
entirely different.

Since it is setup correctly when opening the device it looks like the 
same stuff has to be done when tuning? Maybe a forced CAM-reset or 
something? Well.. Now I'm just guessing.

Since the driver is the same for DVB-T and DVB-C both types should 
experience the same problem.

Isn't there anyone else on this list with this device with access to a 
CAM/CI that could help? Pretty please? :-)

Thanks again for the response. Sorry I couldn't help with USB snooping .
It is a very good device and I sure would like to get it to work even on 
kaffeine :). It's quite new. Still in production and with working CI. 
That is a rare thing in Linux.
