[pvrusb2] New driver snapshot: pvrusb2-mci-20060326

[Mike Isely]

There's a new driver snapshot available.  All the info is in the usual 
place:

   http://www.isely.net/pvrusb2.html

This snapshot includes even more stuff to support the new model 24xxx 
hardware.  And in fact there's enough present in the driver to get the 
hardware to work now.  HOWEVER, (1) It isn't stable enough yet, (2) You 
have to modify a critical #define in the cx25840 module source code 
(search for FWSEND and change it from 1024 to 48), and (3) You need to 
specify "force=-1,27" as part of a manual modprobe of wm8775 before 
composite and s-video input are going to work.  The stability problem is 
the worst issue right now - more description is needed there to explain 
how to identify and work around it.  (The good news there however is that 
once you hotplug the device into the system and survive initializing the 
driver and the hardware, then it is rock stable from that point forward.)

I'll post more detailed instructions about this later, but I wanted to get 
this snapshot out before I start tearing into the driver at a deeper level 
(something needed for kernel inclusion).

I am very interesting in knowing from people that this snapshot does not 
introduce any new instabilities in the old hardware.

Also, this snapshot does not attempt to fix the AMD64 compilation problem 
that Andreas had.  Unfortunately I can't reproduce that problem in my x86 
build environment.  I have a suspicion what the problem is, but no means 
to test for it, and while it *will* get fixed eventually, it was more 
important to get this released now...

I found an interesting I2C bus analyzer product online today.  I'm 
probably going to purchase it in order to continue chasing the stability 
issue.
