great to hear about the specs.

  if you need a tester for mt2060 based device (same dongle what you can see on bttv-gallery site) feel free to send me some code for testing.

Quick update - I've got both the specs for the AF9005 and the AF9015
now, with the specs from the older device I'm starting to make sense of
the Luca's driver. Turns out the AF9015, while having some similarities
to the 9005, does have a different configuration sequence and is notably
different. I'd been originally hoping they'd be similar enough to
incorporate the 9015 into the 9005 driver, but now I think I'll be
writing a separate driver, based on the 9005 one.
I am starting to feel confidant I'll  be able to get something going
though, which is a good place to be.

Well I'm making some progress here, but I feel I'm shooting in the dark a bit. I've got the firmware loading, using the firmware that was in the sample code (it's a big array of data packets to be sent). So replacing the AF9005 firmware code with new stuff to copy the firmware on, I get it loading fine and the dongle responds that it has switched to firmware mode. Obviously I've got the basic low level usb communicaton working, which in itself was a bit of a chore. Afatech didn't keep much the same between the old and the new chip, but the 9005 still seems more similar to my 9015 than other chips source files I've been browsing.

But now I'm getting lost....there's just so much to do I don't know where to start. Is there any documentation around describing what needs to be implemented where to fit into the dvb-usb framework? I can't seem to find much, and wading through the header files feels like I'm just hitting things at random.
I've been trying to focus on getting the i2c working, the AF9015 chip has got a different interface to the AF9005, so that needs a considerable re-write, but again I don't know what interfaces need to be written to handle what information. There's a few structs being passed around here and there but I don't know what I have to handle, and what needs to be passed down the i2c verbatim.....It doesn't help that I've got a qt1010 tuner rather than the mt2060 that the af9005 code is written for.

Speaking of the qt1010, the sample code I've got has got routines to use the qt1010 tuner, whether they might be of some use to the guys working on getting that tuner operational at the moment?

So basically I'm asking if there's any documentation around on what to implement, or at least some pointers in the right direction?

Cheers,

Andrew Leech
