Just for sake of demonstration, some time back i had posted a dummy driver how it can be done in a nice and clean way as an example. The patch assumes some additional standards, you can ignore them. But you get the general idea from in there. http://marc.info/?l=linux-video&m=117613833119350&w=2 > >> There is no reason why the Xceive driver cannot be merged into the >> current development tree using the hybrid tuner framework as it stands >> today. > > I'm not convinced this is entirely true.

You can read this post also for some additional information. http://marc.info/?l=linux-video&m=117922735929375&w=2 Use the ideas as you deem fit. ;-) Manu _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
