Hi Luca, All,
I'm attempting a port of your driver to the AF9015 chip, and slowly 
making progress. Just for reference, I've never written drivers for 
computers before, pretty much all my programming experience is in 
embedded stuff, it's much simpler there.

My biggest stumbling block at the moment is the firmware file. How did 
you know where to extract the firmware from (af9005.fw & 
af9005-script.h)? Was it simply through the documentation you were 
given, or was it through windows snooping?

I've sent Afatech an email asking for access to documentation on this 
newer chip, no reply yet, so just working with what I've got. This chip 
is at least somewhat different to the 9005, as simply adding the PID/VID 
of my device into the driver didn't work, I get a "af9005: boot bad 
config header." An extra err printout tells me that the buff[2] value 
that gives the "boot bad config header"  is 0x0 when it should be 0x11 
for your driver.  

I think I might be in this for the long haul, I've got to contend with a 
different tuner as well, I've got the QT1010 which seems to have pretty 
patchy support under linux.
