Dear Devs, Dear Mike,
as you requested here below is the output of 'modprobe cx23885 i2c_scan=1'
I'm not going to make any pressure on you, however please consider I'm available for any beta testing work or any other help that could ease your work. 

I did a little googling for the tuning chip xc3028 and found George Kiagiadakis (Gkiagia) has already started working on it http://mcentral.de/wiki/index.php/Xc3028 (http://mcentral.de/firmware/firmware_v4.tgz I tried copying these firmwares inside /lib/firmware/linux-blahblah/ but Kaffeine is still not able to scan for channels) maybe I should try with the experimental trunk, so far I used a mercurial snapshot of http://linuxtv.org/hg/v4l-dvb trunk. 

If you need any more information please do not hesitate to send me an email!
In the meantime I thank you for your efforts and wish you a good work.

Michael Krufky <mkrufky at linuxtv.org> a écrit :It would be helpful to see the output of 'modprobe cx23885 i2c_scan=1' , 
after first doing 'modprobe -r cx23885' -- I have this card also, and 
I'd like to make sure that we have the same revision.

I started working on this one, but I've been held up due to firmware 
issues--  So far, the working ATSC linux drivers for the xc3028 have all 
worked when coupled with an LGDT3303 demod.  In your device, we have a 
Samsung demodulator, instead.  The xc3028 requires a different firmware 
image in this case, and I haven't yet found time to work that out.

I'd expect to have the details sorted within the next month or so, but I 
don't want to make any promises.
