As it looks like my AverTV Hybrid Volar HX is a little bit of no use
for quite some time -
and your afatech driver seems to helpfull to many other users - maybe you could
try to make it help for me as well ??

What do I need to do ?

I've got somewhere some old   dvb-usb-af9015.fw size:15913  md5:
dccbc92c9168cc629a88b34ee67ede7b
(Unsure where do I get the latest one ?))

Then I have added patch (see attachment) to enable usage of your
af9015 driver with my USB stick.

And then I get this dmesg error (with debug=63)

So this doesn't look like a usable for now - is there any chance this
will ever work ?

Thanks
