[linux-dvb] AverMedia card firmware?

[Nigel Pearson <nigel@ind.tansu.com.au>]

	Hi. I have been trying to get this working for a few weeks now,
and need a little help.

	I have tried a 2.4.24 and a 2.6.1 setup (both with EPIA-specific
patches, if that matters), and with apppropriate patches from bytesex,
the card seems to be recognised:

% dmesg
...

	but tuning always fails:

	When I unload and reload the frontend:

% dmesg
...
i2c_adapter i2c-1: sendbytes: error - bailout.
sp887x_initial_setup: Unable to open firmware 
/usr/lib/hotplug/firmware/sc_main.mc
DVB: registering frontend 0:0 (Microtune MT7072DTF)...

%

	it complains about firmware. I have not found any relevant
firmware on linuxtv.org or the web, so do I assume this is a
bogus message?

	Anyone know what might be happening here?
