Richard, sorry I didn't immediately reply again but I'm glad you got it 
fixed.

I was thinking after your other reply that if you had installed v4l-dvb 
over the top of your existing kernel, then a follow-on kernel update (as 
part of a package update that you might have done) probably would have 
overridden your v4l-dvb installation - thus the problem surfaces.

As I had said earlier, the pvrusb2 driver used to expect FX2 firmware 
that was only 8KB in size.  About a year ago it was discovered that 
Hauppauge had started shipping firmware that was 16KB in size, which was 
rejected by the pvrusb2 driver at the time.  The fix for the driver was 
easy, but it takes a while for changes to find its way into the kernel 
tree and especially if you're using a stock distribution supplied kernel 
(which will be older) then it probably will have the pvrusb2 prior to 
that fix.  When I made this fix, I also got the change propagated to 
v4l-dvb shortly afterwards, therefore when you installed the recent 
v4l-dvb snapshot you inherited the 16KB-accepting pvrusb2 driver again 
and that's why it is working again.
