Hi Devin,

Which repository should I use then?
I do understand that USB bridge (CY7C68013A) has to be activated. 
As far as I'm aware that bridge is supported in v4l-dvb drivers but not as a
standalone module but rather as a part of other 'main' modules like cx88.
The question is if my components are generally supported why are not
recognized during modprobe 'modulename' process?
Maybe I have to modify the source and add USB id of my card to certain

I would like to start with analog first.

Hello Daniel,

Don't use http://linuxtv.org/hg/v4l-dvb-experimental, that's a very old

Just loading the modules does nothing.  They won't do anything unless they
know about your hardware.

I would start with the bridge:  CY7C68013A

You need to get the bridge working before you can get any of the peripherals
working (such as the lgdt3304 demod, the 3028 tuner, or the cx25843

Once you have the bridge working, you can set the GPIOs to bring the other
chips out of reset and then do i2c enumeration and device registration.

Do you plan on doing analog support first or digital?
