AverMedia A577 (cx23385, xc3028, af9013)

[Novák Levente]

Hi,

Now that DVB-T is finally available in my town, I would like to ask for
help to make my AverMedia HybridExpress (A577) work under Linux.

This is the information I have gathered so far:

Main chips are the following (see
http://www.ixbt.com/monitor/aver-hybrid-express.shtml for pictures, the
page is in Russian though):

cx23885 (PCIe A/V decoder)
xc3028  (hybrid tuner)
af9013  (demod)

all of these individual chips are already supported under Linux, only
the "glue" is missing between them, I think.

I've also got an A885VCap.inf file (which is some 3164 lines long,
that's why I don't attach it here except if requested), along with other
files (a885vcap.cat, A885VCap.sys, cpnotify.ax, cxtvrate.dll, but also
merlinC.rom and cx416enc.rom) from the Windows driver pack. I don't know
if all of these are really needed, especially cx416enc.rom, since this
card is not supposed to have a hardware A/V encoder.

I would like to ask for help, what is the next step I should take in
order to make this card work?

Yes. Also some code changes for af9013 could be needed. There is no any 
af9013 device currently supported, only af9015 which integrates af9013.

Take USB sniff, parse it and comment out data flow command by command. 
Look meaning of those bytes from existing drivers. Then use debugs to 
see data flow is correct.

Ah, I thought af9013 is already supported.

OK, but this card is not USB but ExpressCard.
