Re: dvb-s2 card "TeVii S472" (cx23885)

[Hendrik Oenings <debian@oenings.de>]

Hi Olli,

I've checked if the chip is M88DS3103 and it is not DS3103, but
DS3002b. LinuxTV says it's just like DS3000 and I've seen that the
TeVii S471 also uses that demodulator.

I've tried just to use the code used by TeVii S471, but then ds3000 says
something like:
* Invalid probe, probably not a DS3000
and there's not even a /dev/dvb/*-device then.
Maybe the card could be unusable too, because it says that there's a
ds3000 on it...

Nevertheless, I've tried your module option with m88ds3103 and my kernel
output is the following:
$ dmesg

I'll try to reinsert the card and check the EFI if there's something
concerning the card.
