[pvrusb2] New Snapshot Report ....getting closer

[Mike Isely]

The cx25840 support is not in the main driver sources yet.  That's what 
you're missing.  What I've been doing is merging specific changes into the 
main drivers sources as I prove that each change is completed.  The 
cx25840 part isn't there yet (but many other parts as you've seen, is 
there).

More comments below..

That's something I can't cause :-)

I added that when a discovery was made that the CD included with the new 
hardware in fact has BOTH old and new drivers on it.  So the extract 
program tells you which driver it extracted from so you can be sure you 
got the right one.

The extract program by the way is far more generic now.  It is completely 
table driven; internal logic just deals with a set of signatures and a set 
of firmware names all programmed via tables.

Not unexpected.  The driver has the new hardware's model number now, can 
handle the new hardware's eeprom type and FX2 firmware, and it can 
correctly detect the need to download the new FX2 firmware (needed an 
entirely new detection method).

Yup.  That's the cx25840 piece I mentioned earlier.  The driver is telling 
you that it hasn't seen a decoder module show up and attach and so it's 
warning you that it can't command a decoder which is not present...

The LED is lit whenever it is trying to stream.  The driver controls the 
LED directly and that's how I have it set up.
